Front

Why is sufficient gravity important for a planet to support life?

Back

Sufficient gravity holds an atmosphere, which is essential for maintaining temperature and protecting life.

Front

What is the significance of a planet's distance from the Sun?

Back

It determines the planet's temperature and whether it can support liquid water.

Front

What evidence suggests that Mars may have once supported life?

Back

The presence of small amounts of water in the soil.

Front

What is the role of gravity in supporting life on a planet?

Back

Gravity helps retain an atmosphere, which is crucial for temperature regulation and protection from space hazards.

Front

How does the surface temperature affect the potential for life on a planet?

Back

Extreme temperatures can make it impossible for life as we know it to exist.

Front

What is the importance of water for supporting life?

Back

Water is essential for biochemical processes and is a key ingredient for life.

Front

What does the tilt of a planet's axis influence?

Back

It affects the planet's climate and seasonal changes.

Front

What is the relationship between a planet's mass and its ability to support life?

Back

A larger mass allows a planet to maintain a stronger gravitational pull, which is necessary for holding an atmosphere.
