Earth - Final Exam Review #1

The planet below is orbiting the Sun. The two sweeps are on opposite sides of the Sun and are labeled t. Though the orbital distance covered in each sweep is different, the time interval for each sweep is the same. Areas A and B are bounded by the arcs of the planet’s sweep in time, t, and the lines between the endpoints of the arc and the center of the Sun. What is the relationship between Area A and Area B:

• Area A is the same size as Area B

• Area A is twice as big as Area B

• Area A is 50% larger than Area B

• Area A is 50% smaller than Area B

Earth travels on an elliptical orbit around the Sun. When Earth is at the point labeled on the diagram, it moves most quickly in its orbit. Which BEST explains this more rapid motion of Earth?

• The Sun’s gravitational pull on the Earth is strongest at this point

• Earth is closest to the Sun’s magnetic field at this point

• Earth is closest to the Sun’s radioactivity at this point

• The amount of solar heat reaching Earth is greatest at this point

Which best describes how energy from the sun helps to maintain life on Earth?

• It heats the Earth's atmosphere and surface, which helps stabilize temperatures on Earth and creates environments more favorable for life to exist.
• It forms the ocean’s water and the oxygen in the atmosphere that organisms need for life functions.
• It prevents the destruction of the magnetic field around Earth that protects all life forms
• It is absorbed by Earth’s mantle, which drives plate tectonics to form new land masses for organisms to live.

Which condition is necessary for metamorphic rocks to form?

• Extreme pressure and heating
• Rapid burial of sediments
• Slow cooling of magma

• Silty clay

• Silt loam

• Clay

Which statement about the formation of a rock is best supported by the rock cycle?

• Sediment must be compacted and cemented before it can change to sedimentary rock.
• Sedimentary rock must melt before it can change to metamorphic rock.
• Metamorphic rock must melt before it can change to sedimentary rock.
• Magma must be weathered before it can change to metamorphic rock.
