SC.6.E.7.5

Over the course of a year, areas near Earth's equator receive more direct energy from the Sun area's near Earth's pole. Which of the following correctly describes one result of this heating pattern?

• a. The poles lose all their heat at night.

• b. atmosphere and oceanic currents distribute heat from the tropics to the poles.

• c. Sunlight overheats the oceans near the equator, making it impossible for sea life to exist there.

• d. Sunlight evaporates a massive amount of surface water near the tropics, creating flooding in the part of the world.

• B)release of fresh water into ocean water as icebergs melt

• C)decomposition of organic matter at the bottom of oceans

• D)release of large amounts of salt from icebergs into the ocean

Which of the following statements about Earth's spheres are false?

• A)The biosphere contains all the living and once living things on Earth

• B)The atmosphere is the layer of gases that surrounds Earth

• C)The cryosphere is all the water from the rivers, lakes and oceans on Earth

• D)The geosphere involves the rocks and materials that make up Earth's layers

Wind, which affects precipitation and temperature and therefore climate, is driven by the sun’s energy. Which best explains how the sun’s energy affects winds?

.

• A) The sun causes consistent air pressure in the atmosphere, which leads to even heating, which causes winds.

• B) The sun causes differences in air pressure that lead to differential heating of the atmosphere, which causes winds.

• C) The sun causes differential heating of the atmosphere, which leads to differences in air pressure that cause winds.

• D) The sun causes even heating of the atmosphere, which leads to constant air pressure in the atmosphere, which causes winds.

As a river enters a sea, a delta often forms as sediment is laid down.  Which statement describes where erosion and deposition mainly take place?

• A) Erosion takes place at the delta, and deposition takes place along the river.

• B) Erosion takes place along the river, and deposition takes place at the delta.

• C) Erosion takes place at the delta, and deposition takes place only at the top of the river.

• D) Erosion takes place only at the top of the river, and deposition takes place at the delta.

Paleontologist discovered fish fossils in the arid deserts of western Egypt. What does the fossil evidence most likely indicate about the area's geologic past?

• a. The desert was once a vast ocean

• b. A giant ocean wave carrying sea life crashed onto the desert

• c. Mountains in the region once provided water from snowmelt

When does erosion takes place?

• A)after water, ice, and wind make rock from soil and sediment

• B)as tectonic plates collide and one plate sinks below the other.

• C)when heat and pressure inside Earth change a rock's structure.

• D)as water, ice, wind and/or gravity move soil and sediment from one place of another.
