Topic 2: Gravity & Tides

Front

What moon phases occur with spring tides? Options: New moon and first quarter, First and third quarter, New and full moon, Full moon and third quarter

Back

New and full moon

Front

What type of tide is represented in the picture? Options: Neap tide because of the tidal bulges, Spring tide because the sun and moon are working together pulling on Earth., Spring tide because of where the Earth is in its orbit., Neap tide because the sun and moon provide opposite forces on the Earth.

Back

Neap tide because the sun and moon provide opposite forces on the Earth.

Front

Which pair of objects has the greatest force of gravity between them? Options: The top pair because they are farther apart., The bottom pair because they are closer together., The top pair because they are moving fast., The bottom pair because they are moving slow.

Back

The bottom pair because they are closer together.

Front

Why do we have tides here on Earth?

Back

We have tides because of how the moon's gravity pulls on different parts of the Earth.

Front

Which type of tide is represented in the picture?

Back

Spring because the sun and moon are lined up and working together.

Front

What moon phases occur with neap tides?

Back

First and third quarter

Front

Spring tides are the highest of the high and lowest of the low tides we see on Earth. They are extreme

Back

True

Front

The sun has more mass than Earth. Why doesn't the moon orbit the sun instead of Earth?

Back

The moon is closer to Earth than the sun so its gravitational pull is more.

Front

Which set of objects has the greatest force of gravity between them? Options: The bottom pair because the spheres have a greater mass., The bottom pair because the spheres are closer together., The top pair because the spheres are further apart., The top pair because the spheres have a smaller mass.

Back

The bottom pair because the spheres have a greater mass.

Front

Back

inertia
