Understanding Tides and Gravity

What is a tide?

• A tide is a seasonal weather pattern.

• A tide is the wind's effect on the ocean.

• A tide is a type of fish.

• A tide is the periodic change in sea level.

What are the two types of tides?

• Spring tides and neap tides

• Oceanic and atmospheric tides

• High and low tides

• Daily and monthly tides

How does gravity affect tides?

• Tides are caused by the rotation of the Earth.

• Tides are influenced by ocean currents alone.

• Gravity causes tides by pulling water towards the Moon and the Sun, creating high and low tides.

• Gravity has no effect on water movement.

What causes high tide?

• High tide is a result of seasonal weather changes.

• High tide is caused by underwater volcanic activity.

• High tide occurs due to the Earth's rotation on its axis.

• High tide is caused by the gravitational pull of the moon and the sun on Earth's oceans.

What causes low tide?

• The gravitational pull of the moon and sun causes low tide.

• Strong ocean currents

• Earth's rotation

• High atmospheric pressure

How does the Moon influence ocean tides?

• The Moon influences ocean tides by exerting gravitational pull, creating bulges in the oceans that result in high and low tides.

• Ocean tides are influenced by the Earth's rotation, not the Moon.

• The Moon has no effect on ocean tides; it's solely the Sun's influence.

• The Moon causes ocean tides by changing water temperature.

What is the Earth's axis?

• A line that marks the equator of the Earth.

• A physical rod that connects the North and South Poles.

• An imaginary line from the North Pole to the South Pole around which the Earth rotates.

• The path that the Earth takes around the Sun.

How does the Earth's movement affect tides?

• The Earth's movement, along with the Moon's gravity, causes the rise and fall of ocean tides.

• The Earth's rotation creates a vacuum that pulls water away from the shore.

• Tides are solely caused by the Sun's position in relation to the Earth.

• The Earth's movement has no effect on ocean currents or tides.

What happens to the sea level during high tide?

• The sea level decreases during high tide.

• The sea level rises during high tide.

• The sea level remains constant during high tide.

• The sea level fluctuates randomly during high tide.

What happens to the sea level during low tide?

• The sea level decreases during low tide.

• The sea level remains constant during low tide.

• The sea level fluctuates randomly during low tide.

• The sea level increases during low tide.
