Summary
Equinoxes is when the sun crosses the plan of earth.The Equator is the line in them middle of the earth that separated it into two part witch if south and north.In south is mostly summer because the earth is Axis is tilt (not strait down).The earth is tilt 23.5 degrees and the shape of the earth is Orbit is a Ellipse. The revolution is when the earth goes around the sun that one of the reason that we have different season and the second reason is because of the angle during the winter the energy from the sun must travel through more atmosphere to reach the poles. also of the sun's energy is spread over a large area.The Revolution length is the distance and the times it take the earth to goes around the sun is 1 year (365 days) and a Hemisphere is a sphere and Equinox is day and night are equal. this topic is about Equinoxes, how does the earth move and how much does the earth tilt and how does we get different season us living things.
