Tides Formative Assessment/Practice

Front

What are tides?

Back

Tides are the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun on Earth's oceans.

Front

What causes high tides on Earth?

Back

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

Front

What celestial body primarily influences tides?

Back

The Moon primarily influences tides due to its gravitational pull on Earth's oceans.

Front

What are spring tides?

Back

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

Front

What are neap tides?

Back

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

Front

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

Back

The relative positions of these celestial bodies determine the gravitational pull on the oceans, affecting tide heights.

Front

What is the role of the Sun in tidal changes?

Back

The Sun also exerts a gravitational force on Earth's oceans, but its effect is less than that of the Moon.

Front

What happens to tides during a full Moon?

Back

During a full Moon, spring tides occur, leading to higher high tides and lower low tides.

Front

What happens to tides during a new Moon?

Back

During a new Moon, spring tides also occur, similar to those during a full Moon.

Front

What is the difference between spring tides and neap tides?

Back

Spring tides are higher and lower than average, while neap tides are closer to average levels.
