Earth Systems
This layer of Earth is where we live and is the thinnest layer.
Crust
Plates moving apart form this type of boundary.
Divergent
The inability to consistently access enough nutritious food is called this.
Food insecurity
Breaking down rock without moving it is called this.
Weathering
This irrigation method uses the least water.
Drip irrigation
This layer is responsible for plate movement due to its slow flowing rock.
Mantle
Plates sliding past each other form this type of boundary.
This farming system keeps thousands of animals in close quarters.
CAFO
Moving sediment from one place to another is called this.
Crop rotation
A scientist describes a layer as extremely dense and made mostly of iron. Which layer is it?
Core
DOUBLE POINTS
Which boundary type is most likely to create mountain ranges?
Convergent
DOUBLE POINTS
Why does hunger persist even when food production is high?
Unequal distribution of food
DOUBLE POINTS
Overgrazing can lead to this long term environmental change.
Desertification
DOUBLE POINTS
Planting crops to hold soil in place is called this.
Cover crops
DOUBLE POINTS
Why is the mantle important to surface features like mountains and earthquakes?
It drives plate movement
STEAL 200 POINTS
A region experiences frequent earthquakes but no volcanoes. What boundary is most likely?
Transform
ONLY SELECTING TEAM EARNS POINTS
Why do CAFOs often lead to environmental problems?
Large amounts of concentrated waste
STEAL 200 POINTS
Why does fertilizer runoff harm aquatic ecosystems?
Causes eutrophication
STEAL 200 POINTS
Why is selective cutting more sustainable than clear cutting?
It preserves the forest
STEAL 300 POINTS
If the mantle stopped moving, what would happen to plate tectonics?
Plate movement would stop
TRIPLE POINTS
Explain why convergent boundaries can form both mountains and volcanoes.
Plates collide and one may subduct creating magma
STEAL 300 POINTS
Explain one environmental benefit of reducing meat consumption.
Less land, water, and methane
TRIPLE POINTS
Explain why eutrophication leads to fish dying.
Decomposition uses oxygen

What is the main goal of sustainable development?
Meet needs without harming future generations
