Natural Resources and Energy
What are the three types of fossil fuels?
What are coal, oil, and natural gas?
How many layers are there in soil? Try to name them.
What are three layers: A horizon (topsoil), B horizon (subsoil), C horizon (bedrock)?
Large slabs of Earth’s crust that float on the asthenosphere.
What are tectonic plates?
What is the Law of Conservation of Energy?
Energy cannot be created or destroyed, only changed from one form to another?
The breaking down of rock by means of a physical change.
What is mechanical weathering?
The plate boundary where two plates move towards each other.
What is a convergent boundary?
Which form of energy do wind turbines turn mechanical energy into?
What is electrical energy?
The breaking down of rock by means of a chemical change, like acid rain.
What is chemical weathering?
What are seismic waves?
The plate boundary where two plates move away from each other.
What is a divergent boundary?
Name two renewable energy sources.
solar, wind, water (hydropower), geothermal, biomass
Rocks crash into each other in a river, chipping off small pieces.
What is mechanical weathering?
The plate boundary where two plates slide past each other in opposite directions.
What is a transform boundary?
What is the difference between nuclear fission and fusion?
Fission splits atoms, fusion combines atoms
What is the difference between weathering and erosion?
Weathering breaks down rock; erosion moves the pieces away.
Lichens growing on a rock release acids that slowly dissolve the minerals.
What is chemical weathering?
What is the asthenosphere, and why is it important?
A soft layer of the mantle on which tectonic plates float.
Fossil evidence, matching landforms, climate evidence, and puzzle-like fit of continents.
What is evidence of continental drift?
