Why does earth’s rotation axis lean toward the sun for only one-half of its orbit?

Chemistry
1 answer:
ohaa [14]3 years ago
8 0

The earth is inclined to the plane of its orbit by 23.5 degrees. Therefore for half the time in its earth on its orbit, the north pole will be inclined towards the sun. During this period, the pole receives six months of continuous sunshine. In the other half of the revolution around the sun, the north pole is tilted away from the sun hence receives darkness for 6 months.

According to the kinetic molecular theory, what effect do collisions between gas particles in a sample of an ideal gas have?
elena55 [62]

According to the kinetic theory of gases, the collisions among the molecules are perfectly elastic, that is, when the collision of the molecules takes place, they bounce off each other with no gain or loss of energy. No repulsive or attractive forces take part at the time of collisions, so energy is conserved.
