The World is Just Awesome

Everyone always talks about the Ring of Fire being this big scary ring, and will be the death of us, that could destroy life as we know it at any moment but i beg to differ. If the volcanoes in Hawaii can explode every other day and still welcome it’s inhabitants to visit and watch it then why should these volcanoes be any different? The earthquakes that occur and cause these volcanic eruptions are usually the result of our tectonic plates shifting so if we should be worried about anything it should be these plates crashing into each other all at once. I believe that volcanoes are beautiful master pieces that Mother Nature has created for us, not these terrible monsters that their made out to be. It is true that if the Ring of Fire were to erupt we would be in a pretty sad shape and as these volcanoes may do the damage, they are not the cause for the destruction. I believe we should be afraid of Techtonic Plates, not Volcanoes.

Killer Whales otherwise known as Orca Whales, can be found in all the oceans throughout the world. These predators are beautiful, but vicious animals. Their food chains are very diverse, they hunt anything from fish life to marine life including: Sea-lions, Seals, Walruses, and even other Whales. I personally love Killer Whales because they can survive in any climate whether it be in the ice cold Arctic regions where the ice caps engulf the sea or in the warming Tropical Antarctic regions where the sun blazes through the open waters all day, this is a very unique characteristic. Their unique spots also give them beautiful characteristics, and along with their beauty Orca’s are very social and playful (they play with their food) which some people describe as a cruel characteristic. “Although Killer Whales are not considered endangered as a whole, some local populations are being threatened by their decreasing food supply. Along with all Marine life these whales are treading in polluted water, and being captured to be put into the Zoo’s we visit which is why they were put on the endangered list in 2007″ claims Wikipedia.org. On the bright side every year with the new tide comes new baby Killer Whale to continue in the ever changing cycle of life.

There is alot of different sea animals that live in the tide pools of the PNW some are sea anemones, purple sea urchins, starfish, colorful sea slugs and tiny crabs.

sea slugs-Some animals move freely through the tidepools. One type carries the common name “sea slug,” although they can be so beautifully colored the name seems an insult. Nudibranch is the formal name for sea slugs, whose soft bodies range from lemon yellow to white and bright red, often with stripes, dots or borders. They come in all shapes from elongated to round, flat or plump. Some have feelers on their backs that sway gracefully as they move through the water.

tiny crabs-Tiny crabs scurry along the bottom of tidepools or hide in crevices or under rocks. One crab, the hermit crab, can be seen dragging a snail shell on its back

starfish-Starfish, or “sea stars,” are a favorite of children exploring the rocky intertidal zone. They move slowly across the rocks on suction feet, which they also use to pry open mussels for supper. Pacific starfish range from bright orange to purple.

There are also alot of plants that live in the PNW some are sea lettuce, iridescent seaweed, and Rockweed.

sea lettuce-The blades feel smooth and slick to the touch. The plant is among the most prolific near the low-tide line.

Iridescen seaweed-The “iridescent seaweed” also has a fitting name. It’s distinctive for its changing hues of red, green and blue. It has an oily look and, like most seaweeds, is slippery when encountered on rocks. It is common on the intertidal rocks, hanging limp where water has receded or spreading its blades to float in tide pools.

Rockweed-another common seaweed of the mid-intertidal zone. As the name implies, it typically attaches to rocks in dense mats. Its many flat, flexible brown to olive-colored branches thave air-filled tips.

Tides determine the rhythm of the ocean. Alot of marine life is affected by tidal waves. Tides can protect life or destroy life by covering them or moving them to a new possibly dangerous enviroment. The types of animals that you would most likely find in tide pools are clams, crabs, snail, ocean birds and many more. The rise and fall of tides shifts sands along the shoreline, exposing prey to preditors. Many animals hunt by the tides, for example, bears hunt for clams by sniffing them out and digging for them. Tides can be a dangerous and a great thing for a changing enviroment.

“The influence of the phases of the moon on the ocean and its inhabitants.”

• The moon has a major influence on the ocean and it tides. As the moon rises and falls every day the ocean tides change. Depending on the pull of the moon, when there is a full moon the pull is stronger the is there is only a crescent. As the moon rises the tide gos out and depending on what phase the moon is in tells how strong the pull is. The moon as the strongest pull in a full or new moon state. so twice a month there are large areas of beach exposed and this is good for sea life and feeding patterns.

part 2:

“The marine food chains are affected by the tide changes.”

• As the tide changes the feeding patterns of sea life are exposed. These feeding patterns have been researched are seem to be very consistent with the tides. When the tide gos out the smaller sea life is exposed,  there are small crab that are land bouned that re lie on the tide going out for there food, they eat the microscopic organisms. There are also birds who feed on the small fish in the shallow water and the small crabs that crawl on the beach. In the case for large marine life they wait for the tide to come in and pray on the small animals that it exposes, such as the animals that relay on the protection of the out tide.

     The intertidal, or littoral zone, is home to a variety of marine life. These marine animals must be able to adapt to the changing tides. There are usually 2 high tides and 2 low tides daily depending on where you’re located.     

• Moisture

     Marine animals need moisture, and when the tide goes out they need to either follow the tide or adapt to this change some other way. For example, periwinkles, a type of sea snail, have a natural “trap door” called an operculum. They can use their operculum to trap remaining moisture to survive when they run out of water.

• Waves

     In some areas, waves coming into the intertidal zone may be very forceful and powerful. Marine plants and animals need to be able to protect themselves from these waves. Kelp, for instance, use a structure called a “holdfast” which they use to attach themselves to rocks or mussels so they can keep themselves in place.

• Salinity

     Due to changes in rainfall, water in the intertidal zone can be more or less salty. This means that the marine life living in the intertidal zone have to be ready to adapt in constantly changing salinity in the water they breathe.

• Temperature

     As the tide goes out in the intertidal zone, the marine life that were submerged underwater, are now exposed to the weather. Either hot or cold, the animals will have to adapt to the changes.

Tides are th rising of the ocean surface caused by tital forces of the moon and the sun acting on the oceans. tides cuase in depths of marine water bodies and produce oscillating currents known as tidal streams, making prediction of tides important for coastal navigation.The changing tide produced at a given location is the result of the changing positions of the Moon and Sun relative to the Earth coupled with the effects of earth rotation and bathymetry of oceans, seas and estruaries.

Tidal changes can have massive effects on marine food chains. Tides can either hide animals from predators or they can have the opposite effect and allow the predators to reach those animals. High tides allow sharks to swim farther inshore to where they can reach smaller fish that hide in the shallower waters. When to tide goes out those sharks are forced out into deeper water leaving the smaller fish safe from being eaten. High tides can wash food onto the shore for small crabs, slugs and other creatures that live in very shallow water. Low tides can also provide food for animals. when the tide goes out i can expose portions of the beach that would normaly be underwater, allowing creatures to hunt for food in tidal pools and other places they would not normaly be able to get to. Tidal Changes can give food to some creatures and take food away from others.

The movie was sweet because we learned a lot about tides and how they effect animal life on and off shores. the movie showed a really great perspective on sea life in tides. Many animals rely on tides for food and for survival. and i thought it was interesting how many animals use the tides for food in sea and off. Bears and wolves eat a lot of animals from the sea that come in from sea and a lot of sea animals such as killer whales use the tides to get animals on the coast.

The movie was really great I liked all of it but Tides stuck out to me more. I thought the tides part of the movie was the best and I enjoyed watching it the most.

The sciencetist are saying that global warming is affecting creatures like the coral reef. They say that the coral reef is suffering the heat stress which that the coral reef is not getting enough oxygen from the water so they die and won’t be able to grow there until the water cools off. But some people say that global warming just is a myth that does not exist it just made up by the sciencetist. The sciencetist predict that in couple years that polar caps will melt and affecting the food chain for the animals who lives up there. The only way the sciencetist can prove that there is global warming is that the ice caps are melting and breaking away by global warming. Nobody  sees that driving our cars and greenhouse gases affect on our enviroment.
