The Earth and Its Movements — Flashcards

Answer

The axis of the Earth is an imaginary line around which the Earth rotates. It runs from the North Pole to the South Pole. The Earth's axis is tilted at an angle of about 23.5 degrees, which affects th…

Answer

Rotation is the spinning of the Earth on its own axis. It takes about 24 hours to complete one rotation. This movement causes day and night.

Answer

As the Earth rotates, one half faces the Sun and gets sunlight (daytime), while the other half faces away and is in darkness (nighttime). This cycle repeats every 24 hours.

Answer

Revolution is the movement of the Earth around the Sun in a fixed path called an orbit. It takes 365 days and 6 hours to complete one revolution. This causes the change of seasons.

Answer

The Earth takes 365 days and 6 hours to revolve around the Sun. Every year, we ignore 6 hours. After 4 years, these 6 hours add up to 24 hours (1 day). So, we add an extra day to February every 4 year…

Answer

Seasons are caused by two things: (1) the tilt of the Earth's axis, and (2) the Earth's revolution around the Sun. Because the Earth is tilted, different parts get direct sunlight at different times o…

Answer

The equator is an imaginary line that divides the Earth into two equal halves: the Northern Hemisphere and the Southern Hemisphere. It is located in the middle of the Earth, at 0 degrees latitude.

Answer

The Northern Hemisphere is the half of the Earth above the equator, up to the North Pole. The Southern Hemisphere is the half below the equator, down to the South Pole. When it's summer in the North, …
