100

A measure of how many different types of organisms are present, this resource speaks to the sustainability of an ecosystem.

What is biodiversity?

100
This is the outer, solid part of Earth, including the crust and upper mantle
What is the Lithosphere?
100
This process occurs from the repeated freezing and thawing of water in rocks
What is frost/ice wedging
100
This was the supercontinent that existed approximately 225 million years ago
What is Pangea?
200

Large scale deforestation hurts farmland efficiency due to the increase in the washing away of soil. This "washing away" is also referred to as

What is erosion?

200
This type of rock is formed as magma cools and hardens
What is igneous rock?
200
This kind of weathering breaks rock down into smaller pieces, but the composition of the rock does not change
What is mechanical or physical weathering
200
This theory tells us that Earth's continents rest on large plates that are constantly moving, causing the continents to move with them
What is the theory of plate tectonics?
300

Most rare earth metals and minerals are found most commonly in and around these dormant structures.

What are volcanoes?

300
This process occurs as sediments are transported downhill and deposited in a river or ocean. It creates sedimentary rocks.
What is deposition?
300
In this type of weathering, a chemical reaction changes the composition of rock from one kind to another
What is chemical weathering
300
At this boundary you can find fissure volcanoes. It is responsible for seafloor spreading and mid-ocean ridges.
What is a divergent boundary?
400

This activity began over 10,000 years ago and involves the domestication of plants and animals for human use and consumption

What is agriculture?

400

These structures are typically found at divergent boundaries between oceanic plates, and are responsible for the formation of a majority of Earth's new lithosphere.

What is mid-ocean ridge?

400
These are agents of erosion (must have at least 3)
What are gravity, water, wind, glaciers, humans, plants, etc.
400
At this plate boundary you are likely to find explosive volcanoes and ocean trenches
What is a convergent boundary?
500

Farmers that are able to increase the efficiency of their yields year after year tend to focus mostly on the health and quality of this natural resource.

What is soil?

500
Fossil specimens are formed through the compaction and cementation of this type of rock around the rigid structures in a decaying organism.

What is sedimentary rock?

500

These are significant examples of chemical weathering (must name 2).

Rusting, oxidation, acid rain, acidification of seashells

500
This describes the churning motion of Earth's mantle, and is what is ultimately responsible for tectonic plate drift.
What is mantle convection?
