Which factor causes earth’s seasons?
a. earth’s distance from the sun during its orbitb. the equator’s division of earth into northern and southern hemispheresc. the tilt of earth’s axis as it orbits around the sund. earth’s completion of its orbit around the sun every 365.25 days

C. the tilt of Earth’s axis as it orbits around the Sun

Explanation:

The hemisphere which is pointed towards the Sun, it is summer in that hemisphere.

The hemisphere which is pointed away from the Sun, it is winter in that hemisphere.

The tilt of the Earth at 23.4° is responsible for the length of a day in the hemisphere.

In the corresponding hemisphere the day is longer in the summer season and the day is longer in the winter season.

Hence, the seasons are caused due to the fact that tilt of Earth’s axis as it orbits around the Sun.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
