Associate Level Material Oceans and Atmosphere Worksheet Using the assigned readings for Week Six, prepare a 50- to 75-word response to each of the following questions. The Oceans 1. What is the composition of seawater? The salinity of seawater ranges from 3.3 to 3.7%. When seawater evaporates it leaves behind sodium chloride, better known as table salt. The other components of seawater are acquired through various methods. One of which is weathering. Chemical weathering of rock releases soluble such as salts of sodium, potassium, and sulfur. 2. What are the three major layers (zones) found in the ocean? Describe each layer briefly. The three layers of the ocean are the surface layer, the thermocline, and the deep zone. The†¦show more content†¦The additions come from the melting of stored water that come in the form of glaciers and ice caps during times of global warming. Subtraction comes from the removal of water to land based frozen forms during times of global cooling. 6. What causes ocean tides? Tides are caused by the gravitational pull of both the moon and the sun. The moon being closer has a greater effect on tides. Water on the side of Earth closest to the moon bulges toward the moon. There is also a bulge away from the moon on the opposite side of the Earth. 7. What is the relationship between plate tectonics and the ocean floor—seafloor spreading, for example? 8. What are different ways that earth materials are moved around in the oceans? Surf is a powerful force. It causes erosion and moves sediment from one location to another. Currents are another manner in which materials are transported through the ocean system. There is a longshore current and a beach drift responsible for disturbing and transporting materials. 9. What are the different types of shorelines? Describe each type briefly. There is a rocky coast, lowland beach and barrier island, as well as coral reef. A rocky coast describes the most common type of costal area. This is where there are vertical wave cut cliffs and horizontal bench cut cliffs. The erosion undermines the cliffs and sends the resulting debris into the ocean forming rough outcroppings. Beaches are not only the sandShow MoreRelatedEarths Dynammic Ocean and Atmosphere785 Words   |  4 PagesUniversity of Phoenix Material Earth’s Dynamic Ocean and Atmosphere I Worksheet From Visualizing Earth Science, by Merali, Z., and Skinner, B.

Snow and ice, both have a high albedo as they both reflect high proportions other Sun’s radiation. A couple examples of a substance having a low albedo would be vegetation (grass or trees) and oceans. Though the albedo of soils and earth does vary as factor such as cloud cover, snow, ice, leaf cover, and land use affect how much radiation a surface can reflect from the Sun.
