Chapter 4 Retest

Front

What is the habitable zone in a solar system?

Back

The habitable zone is the region around a star where conditions are suitable for life, allowing for the presence of liquid water.

Front

Which planet in a solar system is most likely to have conditions similar to Earth?

Back

Planet 3 is the one that would have conditions closest to those found on Earth.

Front

What effect does gravity have on a satellite in orbit?

Back

Gravity causes a change in the direction of motion of the satellite, keeping it in orbit.

Front

What are the necessary conditions for a planet to support life?

Back

I. Moderate planetary temperature averages, II. Atmosphere with necessary compounds for life, III. Presence of water in all phases.

Front

What does it mean for a planet to be in the habitable zone?

Back

It means the planet is at the right distance from its star to have temperature conditions that can support life.

Front

Why does Jupiter have more moons than Earth?

Back

Jupiter's larger size and greater gravitational attraction allow it to capture more objects as moons.

Front

What is the significance of water for life on a planet?

Back

Water is essential for life as it is a solvent for biochemical reactions and is necessary for all known forms of life.

Front

How does a planet's axial tilt affect its climate?

Back

A tilted axis results in seasons, affecting temperature and weather patterns on the planet.

Front

What role does gravity play in the formation of moons?

Back

Gravity allows larger planets like Jupiter to attract and capture smaller objects, forming moons.

Front

What is the relationship between a star's distance and a planet's ability to support life?

Back

The distance from a star affects the temperature of a planet, which is crucial for maintaining conditions suitable for life.
