The daily rise and fall of Earth's waters on it's coastline

Explain why it is hot at the equator and cold at the poles
At the equator, the sunlight hits the Earth’s surface at a 90˚ angle, which results in a more concentrated amount of sun in a given area. At the poles, the same amount of sun is shining but not at a 90˚ angle
