Rocks and Tectonics

What are the three main types of rocks?

• Igneous, sedimentary, and metamorphic

• Crystal, quartz, and diamond

• Granite, marble, and limestone

• Volcanic, tectonic, and seismic

How are igneous rocks formed?

• From the compression of sedimentary rocks

• From the solidification of molten rock material

• From the accumulation of organic matter

• From the evaporation of water

Imagine you are observing a landscape over millions of years. Which process would you expect to see in the formation of sedimentary rocks in this landscape?

• Melting and solidification of magma

• Compaction and cementation of sediments

• Erosion and weathering of igneous rocks

• Evaporation of water from minerals

Explain the formation of metamorphic rocks.

• Metamorphic rocks are formed from volcanic eruptions

• Metamorphic rocks are formed by the cooling of molten lava

• Metamorphic rocks are formed from pre-existing rocks that have been subjected to high temperatures, pressures, or chemically active fluids, causing them to recrystallize and change their mineral composition without melting.

• Metamorphic rocks are formed by the accumulation of sediment over time

What are the three types of plate boundaries?

• Divergent boundaries, convergent boundaries, and transform boundaries

• Subduction boundaries, collision boundaries, and sliding boundaries

Describe the movement at a divergent plate boundary.

• The movement at a divergent plate boundary is characterized by the plates moving away from each other.

• The movement at a divergent plate boundary is characterized by the plates not moving at all.

• The movement at a divergent plate boundary is characterized by the plates moving towards each other.

• The movement at a divergent plate boundary is characterized by the plates moving in a circular motion.

What happens at a convergent plate boundary?

• Formation of mountains, deep ocean trenches, and volcanic activity

• Decrease in seismic activity

• Creation of new oceanic crust

• Formation of deserts and plains

Explain the concept of transform plate boundaries.

• Transform plate boundaries are where two tectonic plates converge and form deep ocean trenches.

• Transform plate boundaries are where two tectonic plates slide past each other horizontally.

• Transform plate boundaries are where two tectonic plates collide and form mountains.

• Transform plate boundaries are where two tectonic plates move away from each other, creating new oceanic crust.

How do tectonic plates cause earthquakes?

• Tectonic plates cause earthquakes by the gravitational pull of the moon

• Tectonic plates cause earthquakes by their movement and interaction with each other.

• Tectonic plates cause earthquakes by volcanic eruptions

• Tectonic plates cause earthquakes by the rotation of the Earth

What is the relationship between tectonic plates and volcanic activity?

• Tectonic plates and volcanic activity are closely related, as the movement and interaction of tectonic plates can lead to volcanic eruptions and the formation of volcanoes.

• Volcanic activity is caused by meteorite impacts, not tectonic plates

• Volcanic activity is completely unrelated to the movement of tectonic plates

• Tectonic plates have no impact on volcanic activity
