UNIT 7 TIDES AND SEASONS EXAM RETEST

Front

What are high tides and low tides?

Back

High tides are the highest water levels in the ocean, while low tides are the lowest water levels. Each occurs twice a day due to the gravitational pull of the Moon and the Sun.

Front

How many times do high tides and low tides occur each day?

Back

High tides and low tides each occur 2 times per day.

Front

What causes tides?

Back

Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans.

Front

Why does the Moon have a stronger influence on tides than the Sun?

Back

The Moon is closer to the Earth than the Sun, making its gravitational pull more significant on ocean water.

Front

What is a Spring Tide?

Back

A Spring Tide is a tide that occurs when the Sun, Moon, and Earth are aligned, resulting in higher high tides and lower low tides.

Front

What is a Neap Tide?

Back

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

Front

What is the role of gravity in tides?

Back

Gravity pulls water towards the Moon and the Sun, creating bulges in the ocean that result in high and low tides.

Front

How does the Moon's orbit affect tides?

Back

As the Moon revolves around the Earth, its gravitational pull causes the water to rise and fall, creating high tides and low tides.

Front

What is the difference between high tide and low tide?

Back

High tide is when the water level is at its peak, while low tide is when the water level is at its lowest.

Front

What are the effects of tides on coastal ecosystems?

Back

Tides influence the distribution of nutrients, the behavior of marine organisms, and the overall health of coastal ecosystems.
