Unit 5 Test Review

A lunar eclipse occurs when the Earth's shadow falls on the moon, blocking sunlight from reaching it.

Yes, dwarf planets can have moons because they have enough gravity to pull objects into a spherical shape.

Meteoroids are primarily made of rock or metal.

There is no life on the moon because it lacks liquid water, has a thin atmosphere, and is exposed to too much solar radiation.

The different colors in auroras are caused by different gases in the atmosphere interacting with solar wind.

A solar eclipse occurs when the moon passes between the Earth and the sun, blocking sunlight from reaching the Earth.

A meteoroid is a small rocky or metallic body in space, a meteor is the flash of light produced when a meteoroid enters the Earth's atmosphere, and a meteorite is a meteoroid that survives its passage through the atmosphere and lands on Earth.

The habitable zone is the region around a star where conditions may be right for liquid water to exist on a planet's surface.

Gravity pulls matter together to form celestial bodies, allowing them to achieve a spherical shape.

The Earth's atmosphere protects life by filtering harmful solar radiation and maintaining a stable climate.
