The area covered by oceans in the Earth’s surface.

Answer to Problem 1RQ
70.8% of the Earth’s surface, which is about 360 million square kilometers, is covered by the five oceans such as the Arctic, Atlantic, Pacific, Indian, and Antarctic.
Explanation of Solution
When viewing from space, the Earth glows blue in color; the presence of oceans are the reason for this blue color. Oceans serve as a giant reservoir for water and other chemicals and the resting place for sediment particles eroded and transported from the continents.
Oceans are the bodies of saline water that composes much of the Earth’s hydrosphere. The Earth has approximately a 510 million square kilometers area and the Oceans cover almost 70.8% of the area on the Earth’s surface, which denotes that approximately 360 million square kilometers are occupied by the five oceans such as the Arctic, Atlantic, Pacific, Indian, and Antarctic.

- Activity 12.5B: Identifying Shoreline Features on a Topographic Map Pg 209The area shown on the Point Reyes, California, topographic map is located directly to the southwest of the San Andreas Fault, in a very tectonically active region (Figure 12.10). As a result, some of this region has recently been uplifted and exhibits characteristics of an emergent coastline. On the other hand, because of the general rise in sea level over the past several thousand years, other areas exhibit features associated with submergent coastlines. Refer to this topographic map to complete the following. 1. What type of shoreline feature is Drakes Estero (located near the center of the map)? 2. Point Reyes, located in the bottom-left corner of the map, is a headland undergoing severe wave erosion. What type of feature is Chimney Rock, located off the shore of Point Reyes? 3. Several depositional features near Drakes Estero are related to the movement of sediment by longshore currents. What type of…arrow_forwardActivity 12.3: Wave Refraction Pgs 202-203Figure 12.2 is a map view of a headland along a coastline. The water depths are shown by blue contour lines. As you complete the following questions, assume that waves with a wavelength of 60 feet are approaching the shoreline from the bottom left of the figure. 1. At approximately what water depth-10, 20, 30, or 40 feet-will the approaching waves begin to touch bottom and slow down? (Hint: Recall that this occurs when the water depth is one-half the wavelength.) 2. Using the wave shown in Figure 12.2 as a starting point, sketch a series of lines to illustrate the wave refraction that will occur as the wave approaches the shore by following these steps:Step 1: Mark the position on the 30-foot contour line where the wave front will first touch bottom.Step 2: Knowing that the section of the wave that touches bottom will slow down first, sketch the shape of the wave front when it reaches the 20-foot contour line.Step 3: Using the same…arrow_forwardCan trace and tell me how they did itarrow_forward
