Our Cosmic Journey: Earth's Year in Space
Every year, Earth embarks on a 584-million-mile trip around the Sun. Imagine being on this voyage! As Earth spins on its axis, one half basks in the Sun's light – it's day there. The other half falls into shadow, creating night. This rotation gives us day and night. As we travel further, we experience the beauty of spring, the warmth of summer, the falling leaves of autumn, and the cold of winter. These seasons happen because of the Earth's tilt on its axis as it orbits the Sun. But the journey is not all fun. The Sun spews harmful radiation into space! But fear not, Earth has protection. The atmosphere and the magnetic field act like a shield, keeping us safe on our journey. We live on a special planet, don't we?
Question 1
Why do we experience day and night on Earth?
Because the Sun moves around the Earth
Because the Earth rotates on its axis
Explanation. As Earth spins on its axis, one half basks in the Sun's light – it's day there. The other half falls into shadow, creating night. This rotation gives us day and night.
Because the Earth's magnetic field changes
Because of the Earth's tilt on its axis
Because the Moon blocks the Sun
Question 2
What causes the change in seasons on Earth?
The Earth's distance from the Sun
The Earth's rotation on its axis
The Earth's tilt on its axis
Explanation. The seasons happen because of the Earth's tilt on its axis as it orbits the Sun.
The Moon's gravitational pull
The Sun's rotation on its axis
Question 3
What protects us from the Sun's harmful radiation?
The Ozone layer
The Moon
The Earth's magnetic field and atmosphere
Explanation. The atmosphere and the magnetic field act like a shield, keeping us safe on our journey.
The Earth's distance from the Sun
The Sun's magnetic field
Question 4
What does the term 'orbit' mean in the context of Earth's movement?
The spinning of Earth on its own axis
The movement of Earth around the Moon
The movement of Earth around the Sun
Explanation. In this context, 'orbit' refers to Earth's voyage around the Sun, which happens every year.
The movement of Sun around the Earth
The tilt of Earth on its axis
