Earth's Layers
Which layer do humans live on?
What do you call the large pieces of the Earth's crust that are constantly moving?
Tectonic plates
Is an earthquake a tectonic or climatic hazard?
Tectonic hazard
What do you call rock that has been broken into smaller and smaller pieces over time?
Sediment
Which type of rocks are weathered, soft & crumbly, often where fossils are found?
Sedimentary rocks
What is the hottest layer of the Earth?
The inner core
Give an example of a landform:
Mountains, valleys, trenches, canyons
What kind of hazard is a tornado?
Climatic hazard
Which type of weathering is the breaking down of rocks caused by living things, such as insects or animals?
Biological weathering
What type of rocks are created after a volcanic eruption when the lava cools?
Igneous rocks
What is the second hottest layer, made of hot, liquid metal?
The Outer Core
What type of plate boundary movement is where the tectonic plates slide past each other, causing earthquakes?
Transform boundary
Which type of hazards are caused by movement of the tectonic plates?
Tectonic hazards
Which type of weathering breaks down rocks in four different ways: abrasion, temperature, root wedging, and frost wedging?
Physical weathering
Which type of fossil is the preserved remains of an animal, like bones or teeth?
Body fossil
What is the layer beneath the Earth’s crust, made up of hot, molten rock called magma?
The Mantle
What is the idea that the continental tectonic plates used to be together, but they drifted apart over millions of years?
Continental Drift Theory
What type of hazards are caused by forces of weather?
Climatic hazard
Which type of weathering is the breaking down of rocks, causing a change in their composition, caused by oxygen or rain water reacting with the mineral grains in rocks?
Chemical weathering
Which type of rocks have been changed by pressure and heat?
Metamorphic rocks
What is the fluid-like layer directly below the lithosphere upon which the tectonic plates float and move?
Asthenosphere
What type of plate boundary movement is where the tectonic plates move away from each other, causing the mantle to be exposed? (Hint: This plate movement often causes volcanoes and rift valleys to form)
Divergent boundary
Which of these is NOT an example of a climatic hazard: tornado, hurricane, or tsunami?
Tsunami
What type of chemical weathering is triggered by pollution?
Carbonization
Which type of fossil is formed when an animal gets trapped by the sticky sap of a tree that has hardened?
Resin fossil
