• deep, massive gas atmospheres, which are made up mostly of hydrogen and helium
• celestial bodies that orbit the sun and are round with its own gravity

Name all 4 terrestrial planets.

What do terrestrial planets consist of?

How is Mercury’s surface similar to the moon’s?

• active volcano
• heavily cratered
• tectonic plates.

What else is Mercury made up of and what is the core made up of?

• largely of volcanic rocks and has a massive partially molten
• filled with craters and filled with active volcanoes which have filled the surface with magma
• large dark volcanic rock, rocks, boulders, powdery dust

What has caused Venus to look like the inside of a volcano?

• powdery dust
• sulfuric acid rain falls
• methane ice, ammonia ice, and water ice

In what rotation does Venus rotate?

• prograde rotation
• retrograde rotation

What has the sulfuric acid rainfall and active volcanoes caused to the surface of Venus?

• buildup of carbon dioxide
• filled with craters and active volcanoes which have filled the surface with magma
• chemical breakdown of rock rich iron minerals

Why is Venus an off limit planet?

• buildup surface with magma
• buildup large dark volcanic rock, rocks, boulders, powdery dust
