Miscellaneous
100
Overgrazing and poor farming methods which ruins the land for growing vegetation. Land becomes dry and dusty and unable to support life
What is desertification?
100
A mixture of naturally occurring minerals which could also include organic matter.
What is a rock?
100
The compositional layer of the earth that we walk on.
What is the crust?
100
Alfred Wegener proposed this theory.
What is the theory of continental drift?
100
2 things that are needed to change rock from one form to another.
What are heat and pressure?
200
The removal of trees and other vegetation from an area.
What is deforestation?
200
This process breaks down rocks into fragments called sediment.
What is weathering?
200
The densest layer of the earth.
What is the core?
200
Tectonic plates are part of this layer of the earth.
What is the lithosphere?
200
This is the top of a fold of rocks.
What is anticline?
300
The growth caused by people moving into cities.
What is urbanization?
300
This kind of rock forms when magma cools and hardens.
What is igneous rock?
300
The physical layer that the lithosphere floats on top of.
What is the asthenosphere?
300
This happens at divergent boundaries in the middle of the ocean.
What is sea floor spreading?
300
The area roughly circling the Pacific Ocean, where many volcanoes are found.
What is the Ring of Fire ?
400
A resource that forms at a slower rate than the rate at which it is used. Like fossil fuels which take millions of years to form.
What is a non renewable resource?
400
This kind of rock forms when high pressure and heat transforms rock.
What is metamorphic rock?
400
This is where convection occurs.
What is the mantle?
400
Name 2 things that form at convergent boundaries.
What are mountains and volcanoes?
400
The crack in the crust that is pushing North America apart from Europe.
What is the Mid Atlantic Ridge?
500
A natural resource that can be replaced at the same rate at which it is consumed.
What is a renewable resource?
500
Process by which sediment is moved from one place to another.
What is erosion?
500
The two types of crust.
What is the continental crust and the oceanic crust?
500
Activity that happens at transform boundaries.
What are earthquakes?
500
This type of fuel is formed from the buried remains of plants and animals that lived long ago. For example, Coal and oil.
What are fossil fuels?
