Rotation
yes
yes
The Earth's rotation on its axis is responsible for the observed motion.
Yes, the earth does spin around its axis. That's what causes the apparent movement of the sun and the stars. If your question was rather what spinning on its axis mean? Ever saw a sphere spinning? It means that.
The rotation of the earth around its axis.
The movement of Earth on its own axis is called Rotation and it causes day and night.
The Earth spinning on its axis would be one, with the periodic rotation of the planets round the Sun being another.
Rotation.
Rotation
the answer is rotation
yes
Rotation
Basically, a body can only have one motion at a time. However:* The movement can change over time. * This motion can be expressed as the sum of other motions, for example, movement along the x-axis, the y-axis, and the z-axis. * If the object is rotating, it's usually convenient to express the movement as a combination of linear movement (of the center of mass) and of a rotation.
The seasons are caused by the tilt of the Earth's axis combined with its movement around the SUN.
The seasons are cause by the tilt of the axis of the Earth. The rotation about axis itself moves very little
Heliocentric is the motion of earth around the sun. Geocentric is the motion of earth rotating about its axis.
