Vocabulary and Weathering/Erosion Notes

Which process breaks rocks into smaller pieces without moving them?

• Deposition drops sediments after moving

• Erosion moves sediments to new places

• Weathering breaks rocks into smaller pieces

• Vegetation grows and slows sediment movement

During the freeze-thaw cycle, what mainly causes small cracks to form in rocks over time?

• Glaciers scraping rocks during movement

• Wind pushing sand against rock surfaces

• Water freezing and expanding in tiny spaces

• Plants growing roots into soft sediments

Which list shows the three main agents that cause erosion?

• Sunlight, temperature, and fossils

• Wind, water, and ice

• Heat, plants, and gravity

• Earthquakes, volcanoes, and lava

A stream on a steep hill is carrying sand quickly. What effect will this likely have on erosion compared to a gentle slope?

• Equal erosion because sand size decides

• No erosion because slope does not matter

• More erosion because speed is faster

• Less erosion because speed is slower

After erosion moves sediments, what happens during deposition?

• Sediments melt into liquid water

• Sediments are lifted higher by wind

• Sediments are dropped in a new location

• Sediments are broken into tiny pieces

On a topographic map, what do contour lines connect?

• Places with the same rainfall

• Places with the same temperature

• Places with the same elevation

• Places with the same vegetation

Which map shows a steeper slope: one where contour lines are close together or far apart?

• Close together lines show steeper slope

• Colorful lines show steeper slope

• Far apart lines show steeper slope

• Straight lines show steeper slope

On a geologic column, which layer is the oldest?

• The middle layer is oldest

• The top layer is oldest

• The bottom layer is oldest

• All layers are the same age

A geologic column shows trilobites in the lowest layer and early horses in the top layer. What does this pattern suggest?

• Fossils do not show past life

• Earth stayed exactly the same

• Animals lived at the same time

• The environment changed over time
