Why does the Earth have seasons

• The earth is tilted 90 degrees on its axis

• The earth is tilted 50 degrees on its axis

• The Earth is tilted 23.5 degrees on its axis

• The Earth is not tilted on its axis and it stands up straight

Answer explanation

The Earth is tilted as it revolves around the sun. This changes how much directed sunlight the northern and southern hemispheres' get throughout the year.

What is the invisible force that holds the solar system together?

• Pull

• equal reaction

• acceleration

• Gravity

What would happen to our seasons if the Earth wasn't tilted?

• The entire Earth would have the same season.

• We would have one season all year round.

• We would have many more seasons on Earth.

Answer explanation

If the Earth stood up straight on it's axis there would be no change in how much light parts of the Earth gets as it revolves around the sun. Therefore, the season at any spot on Earth would stay the same all year.
