CC 9-15: The Inner Planets

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What is the main component of the greenhouse effect?

Back

Carbon Dioxide.

Front

How did the solar system form?

Back

The solar system formed from a cloud of gas and dust in space that collapsed under its own gravity.

Front

What is the most massive object in the solar system?

Back

The Sun.

Front

What are faculae on the Sun?

Back

Faculae are bright spots on the Sun's surface that compensate for the dimming caused by sunspots.

Front

What evidence suggests that the Moon has material from another planet?

Back

The peculiar ratio of oxygen isotopes found on the Moon supports the idea that it has material from another planet.

Front

What is the role of the Sun in the solar system?

Back

The Sun provides the necessary heat and light that sustain life on Earth and governs the orbits of the planets.

Front

What are the inner planets?

Back

The inner planets, also known as terrestrial planets, include Mercury, Venus, Earth, and Mars, characterized by their rocky surfaces.

Front

What is the significance of the asteroid belt?

Back

The asteroid belt, located between Mars and Jupiter, contains remnants from the early solar system and helps scientists understand planetary formation.

Front

How do greenhouse gases affect Earth's temperature?

Back

Greenhouse gases trap heat in the atmosphere, leading to an increase in Earth's average temperature.
