2022 Science 1st Semester Exam Review

A boundary where two tectonic plates come together, or collides, is called a

• divergent boundary

• convergent boundary

• transform boundary

• transfer boundary

What can fossils reveal about Earth's past?

• only changes in Earth's climates over time.

• changes in Earth's climates and surface features over time.

• only changes in Earth's surface features over time.

• present climates and surface features of Earth.

What was Wegener's hypothesis?

• Today's continents were once part of a single land mass that split apart.

• The continents are made of rock.

• The continents have always been where they are now.

• The continents will one day join to form a single continent.

Pangaea was Wegener's name for

• the places where plates met.

• the landmass made up of all of the continents.

• the process that moves Earth's plates.

• the lithosphere.

Scientists believe the Earth's inner core to be solid. This is probably due to extremes in

• depth.

• density.

• temperature.

• pressure.

A place where two plates slip past each other is known as

• transform boundaries.

• convergent boundaries.

• divergent boundaries.

• rift valley.

According to Wegener's hypothesis of continental drift,

• Earth's surface is made up of seven major land masses.

• the continents do not move.

• Earth is slowly cooling and shrinking

• the continents were once joined together in a single landmass

What is molten rock that reaches Earth's surface called?

• lava

• magma

• convergent

• divergent

What is molten rock beneath (under) Earth's surface?

• magma

• lava

• convergent

• divergent

What kind of plate boundary is shown here?

• divergent
