Geology 3-8 - Essay Example The motion of plates situated here is continuous and earthquakes occur frequently because California is located in the middle of a fault segment. This means that it is a Transform-Fault Plate type. A tsunami is defined as a strong ocean wave that is the result of mostly an earthquake or at times a volcanic eruption. ( Hamilton, 2005). The causes of Tsunamis are basically earthquakes that cause the sea floor to rise or fall. This happens when plates strike with each other again and again at the border of a plate. Tsunamis occur when the earth’s crust becomes deformed due to earthquakes and the original position of the plates gets disturbed ( Tankut, 2009). Plates try to overlap each other and the heavier ones move under the less dense ones again causing the lithosphere to deform. Other than that, when the sea floor gets elevated or misshaped, a tsunami can be created even then. The Great Pacific Garbage patch, as it name implies is a huge patch of garbage in the northern region of the Pacific Ocean. The size of the patch is still not very clear but it is in the northern portion of the Pacific Ocean. This is due to the fact that plastics do not get destroyed but get converted into harmful substances that keep polluting the air and water around them hence making it dangerous for people who live or travel from there. It has also been damaging submarine and under water equipment as well as wild life. Green House Effect is defined as a process related to physics that captures and traps heat in the atmosphere of the earth. It is a result of the interface between the atmosphere and the sunlight.  Basically, the carbon dioxide that the atmosphere contains absorbs the heat which raises the temperature of the atmosphere. It is not a layer of carbon dioxide in the sky that reflects heat back down as it radiates from the Earths surface. Heat is absorbed by the
