Geology of the Hawaiian Island Chain The chain of Hawaiian Islands formed as the Pacific plate moved over a hot spot in the mantle of the Earth. The plate slowly moves northwestward at a rate of about 32 miles per million years. The northwestern islands are older and generally smaller due to prolonged exposure and erosion. Plate tectonics, types of volcanoes, hot spots, and sea mounts, are all an important part of the geology of the hawaiian island chain.
Oh my gosh! The ground is rumbling! Could it be… the Yellowstone Caldera? Now, you might be asking “What’s the Yellowstone Caldera?” I would tell you to run, but since it isn’t actually erupting, I’ll tell you what it is.
A long time ago when the ground starts to shake, the ocean ate up the coasts, and a dusty vortex sucks up cows, it meant the gods are mad. The ancient Greeks had a way of explaining the cause of many known natural disasters such as volcanic eruptions, earthquakes, tsunamis, etc. Whenever a natural disaster occurs someone somewhere did something to get the gods mad even though no one knew the real cause is the ancient Greek's mentality. Coming back into reality, science says otherwise. We can make conclusions about the cause, effect, and origin of any natural disaster before it happens due to an advancement in modern-day technology.
In the article, Huge Garbage Patch Found in Atlantic Too, Kara Lavender Law, an oceanographer at the Sea Education Association, went on record and described the situation in the Atlantic. " Many people have heard of the Great Pacific Garbage Patch, but this issue has essentially been ignored in the Atlantic." In the Atlantic, this garbage patch spans roughly the distance from Cuba to Virginia and sits between 22 and 38 degrees north latitude. Same as the Trash in the Pacific Ocean, the trash in the Atlantic can filter for years, causing damage to marine life and the ocean.
One of the biggest ones faced by the Central Pacific Company was how to get across the Sierra Nevada mountain range. To conquer this problem, engineers used holes drilled into the rock and filled them with black powder to clear the way (The Transcontinental Railroad, 2012). Once they got into the high sierras black power was not strong enough, and they had to find something more powerful. Nitroglycerin was the solution to their problem. It was illegal to transport nitroglycerin, so what Central Pacific did was hire chemist James Howden to manufacture it on the site as it was needed (The Transcontinental Railroad, 2012).
Instead, its attack was too sudden and inevitable for them to even have enough time to learn to run away from this scary calamity. Well, the blame should go to the dinosaurs as they were not alert to rescue themselves during the critical moment. Photo credit: archeology.net
Imagine a world where a natural phenomenon, like an earthquake, occurs only because someone forgot to pray to Poseidon before bedtime. Back in the height of the Greek empire, this was very believable in the eyes of many. In the technological era, we all now know, and understand, that an earthquake happens when tectonic plates collide with each other. Holly Yan’s article, continues to tell about how today earthquakes happen, with scientific evidence and proof. She would also explain a theory on why their might be another big earthquake coming soon to California.
These tectonic plates are everywhere, under everything from the biggest mountain to the smallest hill. Though it is infrequent, volcanoes have been known to cause tsunamis. It happens when to volcano begins to erupt, but instead of coming out from the top of the volcano a lateral blast shoots out from the side. Next, a quickly moving avalanche of lava pours into the water near it causing the wave to travel to distant coastlines (Springer, 2005).
Volcano Kilauea is the oldest volcano in the world and is 300,000 to 600,000 years old. It 's a big rock that is always surrounded by lava day and night. What if you lived here? How would you survive? The main impacts in this environment are animals, air quality, and humans.
I went to the beach and went swimming almost every day. When I didn’t want to walk to the beach I could go to the back yard and jump in the pool we had. And at night when the pool started to get cold I could go on the upstairs balcony and get in the hot tub. The pool had lights in it but the hot tub had lights and jets. While I was down in North Carolina we went to a place with big sand dunes.

While researching if we should reintroduce grizzly bears into the local San Bernardino and Los Angeles Mountains, I have came to a decision that grizzly bears should be reintroduced. Grizzly bears become extinct in a matter of 75 years. Wikipedia says, "Less than 75 years after the discovery of gold in 1848, almost every grizzly bear in California had been tracked down and killed...grizzlies were never seen again in California. " Now, only 1,800 grizzlies are left in the United States. Like what happened in Yellowstone with the wolves, reintroducing grizzly bears could have great effects on the ecosystem.
