Front

What causes one hemisphere to receive more direct sunlight than the other?

Back

Earth is tilted on its axis.

Front

How does the climate near the equator compare to the climate in South Africa?

Back

The equator receives more direct sunlight through all the seasons of the year and this produces a hotter climate than South Africa.

Front

What is the main reason for the changing hours of daylight throughout the year?

Back

Earth's tilt.

Front

What is the position of the solar system containing Earth in a diagram?

Front

What is the definition of 'axis tilt'?

Back

The angle at which Earth is tilted in relation to its orbit around the Sun.

Front

What is the significance of the equator in terms of sunlight?

Back

The equator receives the most direct sunlight year-round, leading to a warmer climate.

Front

What is the relationship between Earth's revolution and seasons?

Back

Earth's revolution around the Sun, combined with its axial tilt, causes the seasons.

Front

Define 'solar system'.
