Earth's Changing Surface

After an earthquake, 2 streams change course. What would most likely explain the movement of the streams?

• The streams run across a fault in a rift zone where two plates are diverging.

• The streams run across a transform fault that was offset by the earthquake.

• The streams run across a hotspot far from any tectonic plates.

• The streams run across a subduction zone where two plates are converging.

When tectonic plates are diverging, it means...

• the plates are moving towards each other.

• the plates are moving away from each other.

• the plates are moving past each other.

• the plates are not moving.

When tectonic plates are converging, it means...

• the plates are moving towards each other.

• the plates are moving away from each other.

• the plates are moving past each other.

• the plates are not moving.

What is the most likely cause of jagged mountains becoming smoother over time?

• deposition

• weathering and erosion

• movement of continents

• collisions between continental plates

Where is volcanic activity most likely to be found?

• at high elevations

• near plate boundaries

• along seashores

• near magnetic poles

Why do folded mountain belts sometimes form at convergent plate boundaries?

• because subducted oceanic lithosphere melts and rises as magma to Earth's surface

• because rock is compressed and forced upward

• because convergent plate boundaries occur above hotspots

• because the rock is stretched apart and breaks, which allows magma to rise to Earth's surface.

Which evidence could be the result from an asteroid impact on Earth's surface?

• petrified trees that have tree rings showing several years of stunted growth

• alternating layers of lava and volcanic ash erupted from a volcano

• ice cores that show a gradual change in the carbon dioxide content of the atmosphere

• fossils that show a steady rate of evolution in a certain type of organism.

The mid-Atlantic ridge is an area of the ocean floor that is experiencing sea-floor spreading. Where would the newest rock be located?

• The middle of the diagram, where the plate boundaries are moving apart.

• Furthest away from where the plate boundaries are moving apart.

• Closest to the edges of the continents

• All the rock will be the same age.

If the seafloor keeps spreading, how will the ocean change over time?

• It will not change.

• It will get smaller.

• It will become larger.

• It will fill in.

Which evidence would support the idea that increased sea levels have caused erosion over time? choose 3

• global and local temperature records

• historical and modern maps of the area's geography

• continuous tide gauge records around the area

• water temperature, salinity changes and water chemistry data

• composition of sediment cores in the area
