Unit 1
This is the process that explains the movement of landmasses on Earth.
What is plate tectonics?
Alternative methods for growing crops are enacted mostly for this reason.
What is reducing soil erosion?
or
What is restoring soil nutrients?
Oceans cover this percent of Earth's surface.
What is 70 - 75%?
These three areas are where we focused when we earned about pollution.
What is air, water, and soil?
This is the main cause for seasons on Earth.
What is Earth's Tilt?
These are the three cycles we learned about.
What are the water cycle, the carbon cycle, and the nitrogen cycle?
These are the main three nutrients in soil that determine how well a plant will grow.
What are nitrogen, phosphorus, and potassium?
This is where most of Earth's freshwater is found.
What is groundwater?
What is a source of pollution that has a single known origin and what is a source of pollution that does not have a single known, identifiable source.
What are point source and non point source pollution sources?
This is the order of the layers of the atmosphere from Earth's surface outward?
What is troposphere, stratosphere, mesosphere, and thermosphere?
These are the three types of boundaries that can be found between tectonic plates.
What are transform, converging, and diverging boundaries?
What is most wheat produced in the United States used for? What is most corn produced in the United States used for?
What are food products and animal feed respectively?
This is the top of the saturated zone of rock.
What is the water table?
The agency is the American authority on enforcing of environmental protection laws.
What is the EPA?
This day of the year receives the most sunlight.
What is the summer solstice?
These two (technically three) life factors have their own units associated with them.
What are liquid water and the atmosphere? (And also ocean tides)
What is one major limitation of crop rotation?
Many answers.
This structure collects runoff to keep it from causing erosion down hills and allows it to be diverted somewhere else.
What is a terrace?
This pollutant is released from aerosol spray cans.
What are chlorofluorocarbons?
This determines which season a hemisphere is in and explains why the northern and southern hemispheres experience different seasons?
What is direct sunlight?
This feature of Earth creates the magnetic field present around the planet.
What is the rotation of Earth's molten core?
This is each step in the process that turns crops into usable products.
What is crop production, processing, manufacturing, and distribution?
Why might an area use desalination to solve a water problem?
What is not having access to a freshwater source and being are close to the ocean?
This is the most impactful single source of air pollution.
What are volcanoes?
This characteristic is how the cutoffs for the layers of the atmosphere were decided.
What is whether the temperature increases or decreases as altitude increases?
