Tides

Front

What is the change in the force of gravity over distance called?

Back

The tidal force.

Front

During which moon phase are the Earth, Moon, and Sun in a line?

Back

New moon.

Front

What are the extra-strong tides, due to the Moon's elliptical orbit, called?

Back

Proxigean tides.

Front

How long is it between spring and neap tides?

Back

A week.

Front

What is the overall effect of the tidal force on an object?

Back

To stretch an object.

Front

What are spring tides?

Back

Tides that occur when the Earth, Moon, and Sun are aligned, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Tides that occur when the Moon is at a right angle to the Earth-Sun line, resulting in lower high tides and higher low tides.

Front

What causes tides?

Back

The gravitational pull of the Moon and the Sun on the Earth's oceans.

Front

What is the difference between a tidal force and gravitational force?

Back

Tidal force is the variation in gravitational force over distance, while gravitational force is the attractive force between two masses.

Front

What is the role of the Moon in the formation of tides?

Back

The Moon's gravitational pull creates bulges in the Earth's oceans, leading to high and low tides.
