Why can't astronomers directly study the surface of Venus?

• the surface is just way too hot

• the surface is permanently obscured by thick clouds

• there is no surface of Venus

• too many active volcanoes

Forms where plates are moving away from each other

• Divergent-

• Convergent-

• Transform-

Formed where two sections of Earth’s crust are colliding

• Divergent-

• Convergent-

• Transform-

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

The three types of plate boundaries are

• Convergent, divergent, change

• Divergent, allegiant, insurgent

• Convergent, divergent, transform

• Push, pull, slide
