Earth's Surface
What is the crust of Earth?
Layer of rock on Earth's outer surface
Define erosion
Water, ice, gravity, and wind working together to move weathered pieces of rocks
What kind of volcano is Kilauea?
Active Volcano
Give me 2 examples of landforms
Mountain, Hill, Plateau, Plain, Volcano, Canyon, and Valley
Does deposition happen slowly or happen very fast?
Both
What is the difference between magma and lava?
Magma - inside of the volcano, lava - outside of the volcano
Define weathering
Rocks in Earth's crust that are slowly being broken into smaller pieces
List 3 things that cause both erosion and deposition?
Water, Wind, Gravity
The shake comes from rocks breaking because the plates put too much pressure on the rocks
What are the 5 causes of weathering?
Water, ice, temperature changes, chemicals, and living things
What is one way to prevent avalanches?
Clearing away snow before too much builds up.
List 3 things that is the effect of an earthquake and volcano.
Tsunamis, blocking of sunlight because of ashes, damaging of broken gas lines, buildings, roads, and bridges
Why do cracks in rocks get larger because water has frozen in there?
Ice in rock takes up more space than water, so ice forces the sides of the crack outward. The crack goes deeper into the rock and gets later when the process is repeated.
Why is erosion and deposition more likely to happen when land does not have other trees or plants?
There is nothing to stop wind and water from eroding rocks and soil
Explain the difference between violent eruptions and quiet eruptions
violent - pressure from gasses build up and thick magma bursts
quiet - slower and thinner moving magma oozes out of the volcano
