Tides Formative Assessment/Practice

Front

What creates high tides on Earth?

Back

High tides are created when gravity pulls on the water, creating bulges on two sides of Earth.

Front

What are spring tides?

Back

Spring tides occur during the full Moon and new Moon phases when the gravitational forces of the Moon and Sun align, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Neap tides occur during the first quarter and last quarter Moon phases when the gravitational forces of the Moon and Sun are perpendicular, resulting in lower high tides and higher low tides.

Front

What force is responsible for creating tides on Earth?

Back

The gravitational force is responsible for creating tides on Earth.

Front

How do the positions of the Earth, Moon, and Sun affect tide heights?

Back

The relative positions of the Earth, Moon, and Sun determine the height of tides; aligned positions create higher tides (spring tides) and perpendicular positions create lower tides (neap tides).

Front

What is the effect of the Moon's gravity on Earth's oceans?

Back

The Moon's gravity pulls on Earth's oceans, causing water to bulge out in the direction of the Moon, creating high tides.

Front

What happens to tide heights during a full Moon?

Back

During a full Moon, spring tides occur, resulting in higher high tides and lower low tides.

Front

What happens to tide heights during a new Moon?

Back

During a new Moon, spring tides occur, resulting in higher high tides and lower low tides.

Front

What is the relationship between the Moon phases and tide types?

Back

Spring tides occur during the full Moon and new Moon phases, while neap tides occur during the first quarter and last quarter phases.

Front

How can you model the positions of the Earth, Sun, and Moon during the lowest tides?

Back

To model the lowest tides, place the Earth (baseball) between the Sun (basketball) and the Moon (golf ball) in a straight line.
