Earth’s Layers
What is the detention of the earths crust?
Earth’s thin, solid outer layer. It’s where we live. It includes continental crust (generally thicker) and oceanic crust (generally thinner).
What are tectonic plates?
Tectonic plates are large pieces of Earth’s lithosphere.
This is a very high area of land with steep sides.
mountain
This climate zone is usually hot and receives a lot of rainfall.
tropical
Describes how people use, change, and respond to the environment.
Human-environment interaction
What is the mantel?
Mantle: Thick layer beneath the crust. It is mostly solid rock, but it can flow very slowly over long time periods due to heat and pressure.
Plates that move towards each other.
Convergent boundary
This is a large body of salt water that covers much of Earth.
ocean
Pennsylvania is located in this major climate zone.
temperate
All living things and the places where they live; these four systems are connected.
Biosphere
What is the definition of the Earth's core?
Core: Earth’s densest center layer, made mostly of iron and nickel.
Plates that move away from each other.
Divergent boundary
The Appalachian Mountains are an example of this type of landform.
mountain range
Which climate zone would you expect to find near the North and South Poles?
polar
This occurs when harmful substances from factories, vehicles, power plants, and burning fuels enter the atmosphere
Air pollution
What is the outer core?
Outer core: liquid metal
A fracture (crack) in Earth’s crust where movement can occur.
Fault
A river can change the land around it by carrying soil and rocks. What process does this?
erosion
A region with very little rainfall and large deserts most likely has this climate.
Arid
Planting different crops in the same field during different growing seasons.
crop rotation
What is the inner core?
Inner core: solid metal
Plates that move horizontally past each other.
Transform boundary
Put these water cycle processes in the correct order: condensation, collection, evaporation, precipitation.
Evaporation → Condensation → Precipitation → Collection.
A region is located close to the Equator and has high temperatures and frequent rainfall. Based on these physical characteristics, which climate zone is it most likely in?
tropical
Recycling, renewable, energy, sustainable agriculture, and habitat restoration can reduce harm.
