2. Four differences could be:
1) Outer planets are much farther away from the sun, so they get less sunlight than inner planets.
2) Also, the outer planets are all gas giants (excluding Pluto), while inner planets are all rocky planets.
3) Inner planets also have a much higher density than outer planets.
4) Outer planets also tend to have many more moons than inner planets (such as Jupiter, with 63 known moons).
3. The barrier that separates the inner from the outer planets is a ring of space rocks known as the Asteroid Belt.
A comet is a ball of ice that orbits a star in a wide elliptical orbit.
An asteroid is a large rocky body that orbits a star, and could be anywhere in size from 600 miles across to tiny dust particles.
A meteoroid is a small object floating through space freely (not necessarily bound in any orbit) that is usually made of a rocky or metallic material.
4. Day and night are caused by the earth's rotation on its axis. Night is relative to the observer, and occurs when the observer is on the side opposite that on which the sun is shining.

All moving bodies aren’t necessarily accelerated. To be identified as accelerating, a body should have its velocity changing. Thus a body in uniform motion is not accelerating since its velocity is constant.

The displacement is the vector quantity that defines the distance and direction between two positions. It is a change in your position.
What is displacement?
A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions.
It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.
The average velocity, which is a vector for motion over a certain amount of time, is determined by dividing the displacement by the duration of the time interval.
Hence, the displacement is the vector quantity that defines the distance and direction between two positions. It is a change in your position.

I believe you're talking about displacement. It's a directional vector that depicts the movement of a point between two instances.
