• outer core

• crust and upper mantle (oceanic and continental plates)

• all the above

What part of Earth is a heated, semisolid material that flows due to convection currents in the mantle?

• lithosphere

• asthenosphere

• inner core

• True

• False

Basalt - black igneous rock has no visible crystals. Which statement best describes how this rock likely forms?

• The rock cooled slowly below ground, and tiny crystals formed.

• The rock was under a lot of heat and pressure, so no crystals formed.

• The rock cooled quickly above ground forming crystals too small to see.

• The rocks never cooled
