From Seasons to Salmon: All About Cycles! | SciShow Kids Compilation

The video explores various natural cycles, starting with the cycle of seasons, which is caused by Earth's tilt and orbit around the sun. It explains how different parts of the world experience different seasons simultaneously. The phases of the moon are discussed, highlighting how the moon's orbit around Earth affects its visible shape. The water cycle is described, showing how water moves from clouds to rain and back again. Finally, the salmon life cycle is detailed, illustrating the stages from egg to spawning adult and their migration journey.

What causes the different seasons on Earth?

• The tilt of Earth's axis

• The speed of Earth's rotation

• The distance of Earth from the sun

• The shape of Earth's orbit

Why do different parts of the world experience different seasons at the same time?

• Because of the moon's phases

• Due to the Earth's tilt and orbit
