Erosion
What is weathering? Give an example.
The process of rock breaking apart. Ex: Finding smooth stone while walking on the beach.
What is a glacier?
A huge sheet of ice.
What can we infer about water temperature and erosion rates (how quickly something can erode)
*think of our science experiment with the sugar cube*
Warmer water will cause rocks to erode more quickly.
Draw what a seismograph reading would look like if there was an earthquake.
Mrs. Nylander is judge of drawing
Crust, Mantle, Outer Core, Inner Core
What type of living things can cause weathering?
Trees, plants- things with roots.
What is the process when ice is splitting?
Weathering
What causes water to move downstream?
Gravity
What is the FOCUS when talking about an earthquake?
The point inside the earth where an earthquake begins.
What happens when two plates move against each other?
Most likely, an earthquake
What is erosion?
The process of moving weathered rock from one place to another.
Which landform is the best result of deposition?
1. canyon
2. desert
3. forest
4. mountain
What did the sugar and clay represent in our science experiment?
Limestone (sugar)
Harder rock (clay)
What is an epicenter?
The point on Earth's surface directly above the focus.
Which process begins in the Earth mantle, below Earth's curst?
Volcanic Eruption
What is deposition?
Wind, water and ice are all involved in erosion. However, weathering and erosion are different. What is the difference between wind erosion and weathering?
Erosion moves rocks without breaking them down.
What was the role of the clay in our science experiement?
The clay was harder rock showing that it was not weathered by the water.
Plates cause changes to the Earth's surface as they move. What type of plate movement forms moutains?
Plates push against each other.
How does magma reach earths surface?
Heat and pressure cause magma to rise
What can rivers cause regarding erosion?
Canyons.
What can help stop erosion? Choose the best answer:
1. plant grass
2. water the area
3. fill a hole with dirt
4. put a fence where erosion is happening
1. Plant grass
What is the conclusion of our science experiment?
Running water erodes rock, causing the landforms to change.
What is the newer technology called that measures earthquakes?
Moment Magnitude Scale
1. conduct an experiment
2. visit an active volcano
3. observe the Ring of Fire
4. design a computer model
2. visit an active volcano
