• 2.8.1a Explain that some changes in a planet’s surface are the results of constructive forces (crustalplate movement, volcanic eruption, and deposition of sediment) that occur slowly due to processes(i.e., uplifting, glaciation, deposition of sediments) or occur rapidly due to events (i.e., volcanic eruptions, earthquakes). |
2.8.1b Explain that some changes in a planet’s surface are the results of destructive forces (weathering
and erosion) that occur slowly due to processes (i.e., erosion, weathering, glaciation) or occur rapidly due to events (i.e., slump, creep, mudflow, land/rockslides, tornadoes, hurricanes, earthquakes, volcanoes, flooding and tsunamis). |
2.8.6a Explain how Earth’s crustal plates are influenced by activity in the mantle and core to produce major geologic events (i.e., mountain building, earthquakes, volcanic eruptions, ocean basinformation, sea-floor spreading, and subduction). |
