Which statement about the inner and outer planets is true?

a. the inner planets revolve and rotate slower than the outer planets.
b. the inner planets revolve and rotate faster than the outer planets.
c. the inner planets revolve slower and rotate faster than the outer planets.
d. the inner planets revolve faster and rotate slower than the outer planets.

The correct answer to the question is : D)The inner planets revolve faster and rotate slower than the outer planets.

EXPLANATION:

Before going to answer this question, first we have to know about outer and inner planets.

Outer planets are the planets which are present after the asteroid belt and are generally made up of gaseous substances. The outer planets are the Jupiter, Neptune, Saturn, Uranus respectively.

They are present at large distance from the sun. Hence, their period of revolution around sun is more as compared to inner planets.

The inner planets are present before the asteroid belt. They are Mercury,Venus, Mars and the earth.

These planets are present at smaller distances as compared to outer planets. Hence, their period of revolution around sun is less.

The rotational speed of outer planets and inner planets also vary. The outer planets rotates faster as compared to inner planets.

Hence, the correct answer of this question is the fourth option.

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
