Earth and Sun Exploration

What is the name of the imaginary line around which the Earth rotates?

• meridian

• tropic of cancer

• equator

• axis

How long does it take for the Earth to complete one full rotation on its axis?

• 24 hours

• 48 hours

• 36 hours

• 12 hours

Explain why we experience day and night on Earth.

• Day and night are caused by the movement of the Moon around the Earth

• Day and night occur due to the Earth's distance from the Sun

• Day and night are a result of the Earth's magnetic field

• We experience day and night on Earth due to the rotation of the planet on its axis, which causes different parts of the Earth to face the Sun at different times.

What causes the different seasons on Earth?

• The tilt of the Earth's axis as it orbits the Sun

• The number of clouds in the sky

• The rotation speed of Earth

• The distance of Earth from the Moon

Describe the gravitational force between the Earth and the Sun.

• The gravitational force between the Earth and the Sun is caused by magnetic attraction.

• The gravitational force between the Earth and the Sun is influenced by the Earth's rotation.

• The gravitational force between the Earth and the Sun is determined by the speed of light.

• The gravitational force between the Earth and the Sun is governed by Newton's law of universal gravitation.

What is a solar eclipse and when does it occur?

• A solar eclipse occurs when the Earth passes between the Moon and the Sun, blocking all or part of the Sun's light. This can only happen during a full moon phase.

• A solar eclipse occurs when the Sun passes between the Earth and the Moon, blocking all or part of the Moon's light. This can only happen during a new moon phase.

• A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or part of the Sun's light. This can only happen during a new moon phase.

• A solar eclipse occurs when the Moon passes between the Earth and the Sun, but it does not block any light. This can happen during any moon phase.

What is a lunar eclipse and when does it occur?

• A lunar eclipse occurs when the Moon passes behind the Earth's shadow, creating a partial shadow on the Moon. This can happen during any phase of the Moon.

• A lunar eclipse occurs when the Moon moves out of its orbit and aligns with the Sun, causing a temporary darkening of the Moon. This can happen during a crescent moon.

• A lunar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the sunlight from reaching the Earth. This can only happen during a new moon.

• A lunar eclipse occurs when the Earth passes between the Sun and the Moon, blocking the sunlight from reaching the Moon. This can only happen during a full moon.

How long does it take for the Earth to complete one full revolution around the Sun?

• 365.5 days

• 366.25 days

• 364 days

• 365.25 days

What is the tilt of the Earth's axis and how does it affect the seasons?

• The tilt of the Earth's axis is 10 degrees, and it has no impact on the seasons.

• The tilt of the Earth's axis is approximately 23.5 degrees, and it affects the seasons by causing different parts of the Earth to receive varying amounts of sunlight throughout the year.

• The tilt of the Earth's axis is 45 degrees, and it causes the Earth to spin faster during certain seasons.

• The tilt of the Earth's axis is 30 degrees, and it results in constant sunlight across the globe.

Define the term 'orbit' in relation to the Earth and the Sun.

• The temperature of the Earth's core

• The time it takes for the Earth to rotate on its axis

• The path followed by a celestial body around a star.

• The distance between the Earth and the Moon
