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

A coral reef is formed in an area where temperatures exceed 18 degrees Celsius but do not exceed 30. Also they are formed only at or above sea level. Coral is a limestone reef formed by a colony of organisms which secrete calcium carbonate as their skeletal material.

10. Why do waves change as they approach shorelines? A wave changes as it approaches shore due to the fact that a wave exists not only on the surface but also below water. As a wave approaches shore it comes into contact with the shallow sea floor and this begins to distort the loop shape of the water movement. It causes the wave height to increase while the wavelength shortens.

Atmosphere
1. What is the composition of the Earth’s atmosphere? Air is what envelopes the Earth. Air is invisible and typically odorless. Air has two highly viable components that are aerosols and water vapor. Aerosols are liquid and solid particles so small that they remain suspended. Water vapor in air is expressed in terms of humidity. When ignoring aerosol and water vapor these gasses, termed dry air, are present and known as nitrogen, oxygen, and argon. There are more gases that make up a very minute portion of the atmosphere but play a vital role known as carbon dioxide, neon, and six others.

2. What are the four major layers of the Earth’s atmosphere? Describe each layer briefly. There is the Troposphere, the Stratosphere, the Mesosphere, and the Thermosphere. The
