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

• Because of the Earth's rotation

• Due to the Earth's distance from the sun

What is the main reason the moon appears to change shape in the sky?

• The moon's surface changes

• The sun's position changes

• The moon orbits around the Earth

• The Earth's shadow covers the moon

How many phases does the moon go through in a month?

• Ten

• Eight

• Six

• Four

What process in the water cycle involves water turning into vapor?

• Condensation

• Precipitation

• Evaporation

• Sublimation

What happens to water vapor when it cools down in the atmosphere?

• It disappears

• It evaporates

• It turns into ice

• It condenses into droplets

At what stage do salmon leave their streams and head for the ocean?

• Parr

• Fry

• Egg

• Smolt

Why do adult salmon return to their birthplace?

• To find food

• To lay and fertilize eggs

• To change color

• To escape predators

What is a key characteristic of cycles in nature?

• They repeat in a predictable pattern

• They occur randomly

• They happen only once

• They are always visible

Which cycle involves the transformation of water from liquid to vapor and back?

• Water cycle

• Lunar cycle

• Seasonal cycle

• Life cycle
