The adaption and variation in mollusks all have different and looks and feels but they all have things in common. The morphological feature of the mollusks which means soft body is the feature that they heave more than two cell layers, tissues and organs. Because of the mollusks soft body they have to be very careful because they are so fragile and can get hurt or even killed very easily. They do not have the protection like crabs and animals with shells do, they have to learn to survive on there own without a lot of protection. The mollusks are split into classes called class Gastropoda, Class Bivalvia, and class Cephalopoda. Class Gastropoda includes the species snails and slugs, class Bivalvia is for clams and oysters and the Cephalopoda class is for bigger organisms like squid and octopus. The body semen try for the worm and the squid we dissected was symmetry but the clam was not it was more like a big blob of goo. The worm and squid were both equal if you cut them in half but the clam was not at all. All the dissections we did have very different textures and shapes and even smells. The worm was long and not slimy it was hard and thick skinned. The squid was slimy and squishy more like a sponge. The squid had a few hard parts to it where the worn did not. The clam had a hard shell and a squishy, slimy inside like the squid did, but the squid had eyes and was could swim and is mush bigger. The clams mantle is what keeps it protected from other creatures that may harm it. The mantle also helps from the clam being damaged from tides and currents. The Locomotion of a squid and clam compare is that they both have the same vascular system. Water goes in and out of the there bodies and help them move. A squid and octopus have camouflage because it helps protect them from predictors. Bivalves and Cephalopods do not have camouflage because they have shells that help protect the, and they can hide away were the squids and octopus can not. Bivalves eat by using there gills and they filter feed. Cephalopods eat other organisms like fish, worms and plants. Mollusks and humans are alike they have nervous systems and reproductive systems we share in common. Mussels have a special adaption to stay on shore they use there foot and they hold onto the rock or land. They have very strong leg that holds on and keeps them steady for a while. Octopus have very large brains and are considered by many that they are stupid but in fact they can be smart. They have a very good memory they can tell the difference between colors and toys. They use left and right like we do but they use there eyes to tell the difference. Mollusks help keep our oceans clean they help with the bacteria and mess. They are a big source of food for other organisms and helps keep other organisms reproducing. And there shells are used multiple times when one dies another moves in.

Starfish Dissect
The Sea star also known as a starfish are beautiful creatures that life on our oceans floors. The Starfish is from the phylum Echoinodermata and it means that it is radially symmetrical coelenterate meaning every side of its body is the same looking. The phylum also consists of Sea Urchins, Sea cucumbers and even sand dollars because they all have the same type of systems.
1. Sea Fish are in fact not fish at all because they don't swim they move around on the bottom with tube feet that are helpful for sticking to the ground
2. The Coscinasterias Calamaria also known as the eleven-armed sea star has an arm spread that can go up to 30 cm and it can grow up to 14 arms and a sun star can grow up to 40 arms
3. Sea stars do not have blood instead they have a water vascular system that helps them to move
4. A Sea stars eyes are on the ends of each leg but they are only used to tell if its light of dark
5. A Sea star is born when egg and sperm collide together when they are released into the water a Sea star larvae are not much bigger than pinheads and
the larvae float in the water until they grow a bit and they sink to the bottom.
6. Some species of sea starts do care for there young until they grow but most let there young go and grow up on there own
7. The Sun Sea star are the head of the sea start family as they grow older more arms grow
8. There is a sea star called the leather sea star it isn’t prickly to the touch, but it sure is slippery. This sea star releases mucus over much of its body
9. The crown-of-thorns sea star can harm even humans who touch its long spines. A sting from one of these sea stars can be very painful a person will lose feeling if stung
10. Sea stars always grow back arms if they are cut off or broken and at some point if all the arms fall off they will all grow back if the core is not damaged

How do the fundamentals of physical oceanography and meteorology make earth habitable ?
The fundamentals of physical and meteorology oceanography make earth habitable because.
the climate and winds affect the tides and currents causing waves. The ocean holds most of the earths
heat and food sources. When the ocean reflects the extra heat, the heat goes into the atmosphere
creating rain to fall. The ocean also helps keep the earth at a constant temperature that keeps us from
burning up or freezing to death.
When you are out in the ocean have you ever noticed how windy it is and how if you keep going
further out into the ocean you will notice the waves as they grow and become stronger. These winds
are created because of the wide open space of the ocean. There is nothing blocking the wind from
being slowed down. The winds help to keep the ocean moving from place to place throughout the
ocean. Winds get stronger as they cross through open space. The Arctic for example is extremely
windy because of all the open space across the ice. Other examples of high winds are open fields,
huge open areas and the ocean itself.
The winds go from high to low and low to high. The winds circle around on the outside of the earth.
The ocean adsorbs the suns rays and as the water heats so does the air. The heat circles around as heat
releases throughout the air creating the warm air. The air tarps heat above the clouds, the clouds hold
moisture and when it rains that warm air comes down in rain form. The clouds are like heat trappers
that allow heat into the earth.
The oceans tides, currents and waves create are created by the movement of the moon everyday
creating tides within the ocean. The tides differ in some parts of the world there will be some oceans
that have two tides a day and others that will only have one at night or in the morning. The moon
changes the tides. As the moon comes out in the tide comes in and as the moon disappears the tide
goes out creating the tide change. Tsunamis within the ocean are created when the earth moves, also
known as an earthquake cracks the crust of the ocean bottom moving the plates. The pressure that the
quake causes upward pressure that pushes the water creating waves. The waves then grow as the
wind catches up to the waves and they push towards land. The currents also have an affect on the
ocean.
The currents all move in different directions. The warm and cold waters collide at some points its
called at gyre and its when the cold and warm air mix together creating a circular motion in the
ocean.
The earth is habitable because. The ocean prevents world temperatures from getting to hot or too
cold. Without the ocean we would most likely be dead. Because the earth would burn up, the heat of
the sun would make the earth to hot and the earth would disappear slowly. The ocean creates life for
the humans it does so much for us we should do the same and keep the ocean clean and well because
if the ocean is affected so is earth itself affecting our air and our habitat.

Interactions of the sun, atmosphere and the water to the ocean
How so the interactions between the sun,atmosphere, and water create environmental conditions in the ocean?
Interactions of the sun, atmosphere , and the water create environmental conditions in the water. The atmosphere consists of a stratosphere, thermosphere, trosphere and the mesosphere.The thermosphere is the top layer of the atmosphere, the metosphere and the stratosphere are the middle layers and the troposhere is the lowest layer and it extends from the bottom of the earth. Inside the layers there are many diffent gasses they is oxygen, nitrogen, argon, carbon, and other gasses that hold our planet together. The sun effects the oceans because. The suns rays reflect off of the ocean and the thermosphere. The thermosphere consumes 50% of the suns rays, while the rest is left in the atmosphere. The ocean also consumes the sun rays heating the water. The cycle is a circulation in the from the atmosphere to the clouds and the ocean. The heat that enters the ocean is brought through the by the Gulf Stream, this brings warm water to diffrent parts of the ocean. Pressure is then put on the salt and fresh water creating mixture and currents and waves these are called mouths where salt and fresh water mix. The ocean convayere belt is when salt is carried to parts of the ocean to places that are missing the salt that need it. The polar eastelies winds push downward in the ocean well the polor front winds push back at the eastelies winds. The other winds are called westline winds and they are found between 30 degrees and 60 degrees lattitude toward the poles. When the winds collide its called a gyre. Every ocean has a grye but they are diffrent because the winds directions are diffrent. Many of the currents in the oceans are created by the grye effect. Geostophic currents also create the ocean currents becasue of the earths rotation. Overall the ocean is effected by the sun the atmosphere and the water itself. The oceans are most effected by the earths roatation more than anything else the movement creates winds cretaing the currents and everything else. The suns rays and the atmosphere all work together to make our oceans the way they are.

A Beach By Another Name
Physical and Geological characteristics are used to classify earths dynamic coastlines, using coastal classification by graphing and finding estuaries. The differences of the characteristics defer and can create changes on the ocean floor. Coastlines are different everywhere in the world, in every ocean, bay, delta and rivers.
Coastal classifications are put into groups, primary and secondary coasts. The Shepard Coastal classification system was created to find the differences between coastlines in the ocean. Primary coasts are split into five different coasts types, Land erosion, Subaerial-deposition, Volcanic, Diastrophic, and Ice coasts. Florida for example has primary beaches caused by Subarial-Deposition and land erosion. Secondary coasts are put into three different parts Wave erosion, Marine-deposition and coasts built by organisms. Chesapeake bay is a secondary coast because there are marshlands and grasslands this means its a coast built by organisms. Coastal classifications are very important, they tell us what to look for and what the ocean floor is made of.
Graphing estuary salinity profiles helped to show the differences between estuaries. Graph A explained the depth and salinity, the graph went across than up than across ending on points (10, 30.5). Graph B showed a strait line ending on points (10,20). Graph C showed an staircase looking line which ending points are (10,30.5). Graph A was a coastal plain, Graph B was a Fjord and Graph C was a Tectonic Coast. graphing the estuaries helped explain how the estuaries effect the different places and sections in the ocean.
Estuaries are considered as nurseries in the ocean, they protect organisms from currents and waves. Fish will go to the estuaries to lay eggs to keep them protected from predictors. there are four types of estuaries Coastal Plain, Fjords, Bar built and tectonic estuaries. San Francisco Bay is a coastal plain because its a small river into a big body of water. The Indian river is a tectonic because there are barriers holding in the water. Puget Sound is a fjord because its a river. Biscayne Bay is a bar built because its man made land around the the ocean. Estuaries are very important to our oceans because they help to bring in life to the ocean, they keep fish protected and its a great place to go fishing.
This activity helped me to understand the greatness of the ocean and how important estuaries are to the ocean and the sea creatures. I learned how different coastlines effect the ocean and all around the United States coasts. Coastlines are very different and help keep the ocean moving. If coastlines where all the same the ocean would not move as smoothly because all the different coastlines have effects on the ocean and without them the ocean would not be as it is today.
