Tectonic Plates Earth and Space

What is the difference between a divergent boundary and a convergent

boundary?

• Divergent boundaries slide past each other horizontally, and

  convergent boundaries form mountain ranges and ocean trenches.

• Divergent boundaries run into each other, and convergent

  boundaries pull away from each other.

• Divergent boundaries pull away from each other, and convergent

  boundaries run into each other.

• Divergent boundaries form mountain ranges, and convergent

  boundaries slide past each other horizontally.

What is a tsunami?

• An earthquake caused by plates sliding past each other

• A volcano that has been formed from magma seeping out of the asthenosphere

• The layer of earth under the crust

• A giant wave caused by an earthquake in the ocean basin

If a convergent boundary involves a continental landmass and an ocean basin, what is the result?

• A chain of volcanic mountains will form on the edge of the continent or just off shore; a deep ocean trench will form off shore.

• The land will fold and fault, forming high mountain ranges.

• The land at the edge of the continent will buckle, causing the formation of a trench.

• There will be frequent earthquakes, but no other evidence of crustal movement.

Which of the statements is NOT true?

• The lithosphere is fractured into giant pieces called plates.

• The asthenosphere is a liquid, and the lithosphere is soft and puttylike.

• The asthenosphere is soft and putty-like.

• The lithosphere is composed of the upper part of the mantle and the crust.

What is the main point of this passage?

• Scientists can predict earthquakes, but not tsunamis.

• Tectonic plates have moved and reshaped continents, created and destroyed ocean basins, and caused earthquakes.

• Meteorologists can broadcast news quickly about approaching disasters.

• Shifting of tectonic plates can change people’s live
