Unit 5 Mock Test

Front

What causes high and low tides on Earth?

Back

Tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans. When the Moon is closest to Earth, high tides are higher, and when it is farthest, low tides are lower.

Front

Why are summer days longer than winter days?

Back

Summer days are longer because the region of Earth experiencing summer is tilted toward the Sun, allowing for more direct sunlight and longer daylight hours.

Front

What is the third quarter phase of the Moon?

Back

The third quarter phase occurs when half of the Moon's surface is illuminated and visible from Earth, and it is positioned at a 90-degree angle relative to the Earth and Sun.

Front

What is necessary for a solar eclipse to occur?

Back

A solar eclipse occurs when the Moon passes between Earth and the Sun, blocking the Sun's light from reaching Earth.

Front

How does the tilt of Earth's axis affect the seasons?

Back

The tilt of Earth's axis (approximately 23.5 degrees) causes different parts of Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.

Front

What is the role of the Sun in the solar system?

Back

The Sun is the central star of the solar system, providing light and heat that sustain life on Earth and influencing the orbits of planets.

Front

What is the difference between a full moon and a new moon?

Back

A full moon occurs when the entire face of the Moon is illuminated by the Sun, while a new moon occurs when the Moon is between Earth and the Sun, making it invisible from Earth.

Front

What is the significance of the Moon's phases?

Back

The Moon's phases are significant because they affect tides, cultural events, and can influence animal behavior and human activities.

Front

What is the gravitational pull?

Back

Gravitational pull is the force that attracts two bodies toward each other, such as the Earth and the Moon, influencing tides and orbits.

Front

How does Earth's rotation affect day and night?

Back

Earth's rotation on its axis causes different parts of the planet to face the Sun or be in shadow, resulting in the cycle of day and night.
