Front

What causes high and low tides on Earth?

Back

High and low tides are caused by the gravitational pull of the Moon and the Sun on Earth's oceans.

Front

What is the significance of the Moon's orbit in relation to tides?

Back

When the Moon is closest to Earth, its gravitational pull is stronger, resulting in higher high tides and lower low tides.

Front

What is the orbital period of Venus around the Sun?

Back

Venus orbits the Sun once every 225 Earth days.

Front

What should an astronomer do if their findings differ from widely accepted data?

Back

The astronomer should gather a new set of data to verify the results.

Front

What type of galaxy is characterized by spiral arms?

Back

A spiral galaxy is characterized by its spiral arms and a central bulge.

Front

Who was the first scientist to provide evidence for the expanding universe?

Back

Edwin Hubble was the first scientist to find evidence that the universe is expanding.

Front

What model can best explain the changing seasons on Earth?

Back

A model using a basketball with thermometers taped to different parts can demonstrate how the tilt of Earth affects temperature and seasons.

Front

What is the role of the Sun in the Earth's seasons?

Back

The tilt of Earth's axis relative to its orbit around the Sun causes the seasons to change.

Front

What is a spiral galaxy?

Back

A spiral galaxy is a type of galaxy that has a flat, rotating disk containing stars, gas, and dust, along with a central concentration of stars known as the bulge.

Front

What is the gravitational effect of the Sun on Earth?

Back

The Sun's gravity keeps Earth in orbit and influences tides, although the Moon has a more significant effect on tidal changes.
