Plate Boundaries
At these plate boundaries, the plates are crashing into each other. Very, very slowly, but crashing.
What are convergent boundaries?
This is a variable that doesn't change in an experiment.
What is a constant?
This type of rock is made by processes on Earth's surface.
What are sedimentary rocks?
This type of energy flow drives plate tectonics
What is convection?
This is the destruction of trees. Don't they make oxygen for us?
What is deforestation?
These plate boundaries are moving apart.
What are divergent boundaries?
This group is the baseline in an experiment, what you measure results against.
What is a control group?
These rocks are changed by heat and pressure inside the Earth.
What are metamorphic rocks?
This landform is made from deposition where a river meets a lake or ocean.
What is a delta?
When we build cities, this is the result.
What is urbanization?
These plate boundaries slip past each other.
What are transform boundaries?
This is the variable that you change in an experiment.
What is the independent variable? (Or test variable)
This type of rock results from melting rocks.
What are igneous rocks?
This type of weathering changes the rock into new substances.
What is chemical weathering?
When we destroy once fertile land.
What is desertification?
This plate boundary is where subduction zones may take place.
What are convergent boundaries?
This variable is your results.
What is the dependent variable? (Or outcome variable)
This type of rock can become an igneous rock.
What is any rock?
These tiny rocks are often found where people enjoy the oceans.
What is sand?
The result of air pollution, much of it coming from cars.
What is bad air quality?
Transform boundaries are the only one that never produces these geological features.
What are volcanoes?
This is the type of experiment where all variables are under the experimenter's control.
What is a controlled experiment?
This is the breakdown of rocks
What is weathering?
This landform is found at the base of a mountain, formed by the deposition of mountain sediments.
What is an alluvial fan?
When all the soil washes away because we killed all the plants.
What is erosion?
