Plate Motion Mid-Unit Assessment

Earth's "outer" layer is made of

• hard solid rock

• soft solid rock

• sediment

• magma

Geologists look for patterns in land forms such as those made by

• connecting roads

• tiger prints

• human tracks

• earthquakes and volcanoes

Earths outer layer is divided into sections called

• zones

• plates

• continents

• countries

New plates are formed at the

• Convergent Plate Boundary

• Divergent Plate Boundary

• Transform Fault

The plates of Earth's outer layer can

• move very slowly

• move very fast

• not move at all

• move to fast to measure

Earth's plates move on top of a soft, solid layer of rock called the

• plate zone

• diverging zone

• converging zone

• mantle

For plates to travel great distances it takes

• 1 hour

• 2 days

• millions of years

• 5 months

This boundary allows two plates to move away from each other.

• convergent boundary

• fault boundary

• divergent boundary

• transform boundary

Plates are destroyed at

• Convergant Plate Boundaries

• Divergant Plate Boundaries

• Transform Plate Boundaries

Earth's plates move at a rate

• 5 feet per month

• 1 foot per week

• 60 miles per hour

• to slow to be seen by humans but about 1 cm per year
