Unit 2 Checkpoint

Front

What effect would a closer Moon have on the frequency of high tides?

Back

High tides would occur more frequently due to the stronger gravitational pull from the Moon.

Front

How would you improve the model to make it more accurate? Options: Draw the Moon orbiting Earth at all points, Draw Earth twice as far from the Sun when it is winter, Draw Earth tilted in the same direction at all points, No improvement is needed. The model is correct.

Back

Draw Earth tilted in the same direction at all points.

Front

What has the largest effect on the motion of the planets within Earth’s solar system?

Back

the gravitational pull of the Sun

Front

Claim: Earth and Mars are both terrestrial planets and have nearly the same physical properties.

Back

Earth has a surface gravity of 9.81 m/s², and Mars has a surface gravity of 3.71 m/s².

Front

Which positions of the Sun, Earth, Moon, and the beach predict low ocean levels exposing seashells? Options: The Sun, Earth, and the Moon form a straight line with the beach located inside the tidal bulge; The Sun, Earth, and the Moon form a right angle with the beach located inside a tidal bulge; The Sun, Earth, and the Moon form a straight line with the beach located outside a tidal bulge; The Sun, Earth, and the Moon form a right angle with the beach located outside a tidal bulge.

Back

The Sun, Earth, and the Moon form a straight line with the beach located outside a tidal bulge.

Front

Why are carbon dioxide and water vapor called greenhouse gases?

Back

They trap heat like the glass walls of a greenhouse.

Front

How do the phases of the moon affect the tides on Earth?

Back

Full and new moons cause higher tides

Front

The table and graph below show the height of the water in a location in Charleston, South Carolina for a one week period during January of 2004. Based on the data shown, what do you predict will be the pattern for the tides on January 8, 2004?

Back

The highest tide will be during the early morning

Front

What activities would you recommend at each location at this point in the Earth's revolution around the Sun?

Back

Winter skiing at location 1 and a day at the beach at location 2.

Front

Why does the Sun rise earlier in Anchorage, Alaska in July compared to January?

Back

The sun rises earlier in the northern hemisphere in the summer because the north end of Earth’s rotation axis is pointed toward the Sun.
