When the North Pole is tilted toward the sun in the summer, the Northern Hemisphere experiences more daylight. This results in longer days and warmer temperatures.
Earth's axis runs from the north pole to the south pole and is tilted at 23.5 degrees. Rotation is the spinning of Earth on its axis. It takes 24 hours to make one complete rotation.
The moon goes through several phases based on its position in relation to the sun and Earth. When the moon is between Earth and the sun, none of it is illuminated and it is referred to as a new moon.
Earth's tilt on its axis is responsible for the different seasons.
Earth bulges slightly at the equator and flattens slightly at the poles.
The sun is huge compared to Earth. About one million planets the size of Earth could fit inside the sun.
Earth spins, or rotates, at a speed of about 1600 kilometers per hour at the equator.
The tilt of Earth affects the length of day. When the north pole is tilted away from the sun, the northern hemisphere experiences less daylight. But when it is tilted toward the sun, it receives more daylight.
Waning refers to the process of the full moon growing darker as the moon revolves around Earth. The animation depicts the last quarter phase, from which it slowly grows darker and disappears until it becomes a new moon, starting the cycle over again.
Deposition is the process in which sediments are dropped.
A pluton is formed when a large pool of magma builds up under the surface and raises the surface above it. When the pool of magma hardens a pluton forms.
Earth rotates much faster than Mercury. It takes nearly 59 Earth days for Mercury to make one complete orbit.
It takes Mercury 88 Earth days to make a complete revolution around the sun.
Venus rotates so slowly that its day (8 Earth months) is longer than its year (7 Earth months).
Earth's axis is tilted at 23.5 degrees. As Earth revolves around the sun, its axis always points at the same angle, but the direction it points in relation to the sun changes, resulting in different seasons.
There are four distinct seasons in northern latitudes: spring, summer, fall, and winter.
Seasons are used to describe certain times of the year.
The summer solstice is on June 21 or 22. This is the longest day of the year in the northern hemisphere.
The vernal equinox is on March 20 or 21 in the northern hemisphere. There are 12 hours of daylight and 12 hours of darkness on the vernal equinox.
