As the earth spins on its axis , producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth’s spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
How are the seasons caused?
Seasons occur because Earth is tilted on its axis relative to the orbital plane , the invisible, flat disc where most objects in the solar system orbit the sun. ... In June, when the Northern Hemisphere is tilted toward the sun, the sun’s rays hit it for a greater part of the day than in winter.

What is called revolution of Earth?
Earth spins around its axis, just as a top spins around its spindle. This spinning movement is called Earth’s rotation. At the same time that the Earth spins on its axis, it also orbits, or revolves around the Sun . This movement is called revolution.
How many times does the Earth rotate?
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds , called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.
What are the earth movements?
4 The Earth’s Three Motions. The Earth turns (rotation around the polar axis) , goes along on its orbit (revolution around the Sun), swings smoothly as un unbalanced spinning top (equinoctial precession).

What are the two movement of the earth?
As you know that the earth has two types of motions, namely rotation and revolution . Rotation is the movement of the earth on its axis. The movement of the earth around the sun in a fixed path or orbit is called Revolution.
