Which of the following best explains the cause of tides on Earth?

• Tides are caused by the Earth's rotation around its axis.

• Tides are caused by the gravitational forces between the Earth, the Sun, and the Moon as their positions change.

• Tides are caused by the wind blowing across the surface of the oceans.

• Tides are caused by the Earth's distance from the Sun.

Where do the tidal bulges occur on Earth?

• On the side of Earth facing the Sun

• On the side of Earth facing the Moon and the opposite side

• Only on the side facing the Sun

• Only on the opposite side of Earth from the Moon

What happens at the coastlines where the tidal bulges are present?

• Low tide occurs

• High tide occurs

• The ocean remains calm

• Waves increase in height

What is the relationship between the Moon's gravitational force and Earth's oceans?

• The Moon's gravity causes the Earth’s atmosphere to change

• The Moon’s gravity has no effect on Earth’s oceans

• The Moon’s gravity causes two tidal bulges to form in Earth's oceans

• The Moon’s gravity causes earthquakes on Earth

Why does the Moon have a stronger effect on Earth's tides than the Sun, even though the Sun has a much greater mass?

• The Moon is closer to Earth than the Sun.

• The Moon has more gravitational force than the Sun.

• The Moon's orbit is perfectly aligned with Earth's oceans.

• The Sun's gravitational effect cancels out the Moon's effect.

What occurs when the Sun, Earth, and Moon form a right angle?

• A spring tide with the highest difference between high and low tides

• A neap tide with the least difference between high and low tides

• A lunar eclipse, blocking the Moon's light

• A solar eclipse, blocking the Sun's light

What happens when the Sun, Earth, and Moon line up in a straight line twice each month?

• A neap tide with the least difference between high and low tides

• A spring tide with the greatest difference between high and low tides

• A lunar eclipse due to the Earth's shadow

• A decrease in tidal activity
