Rock cycle
True or False: Materials in the Rock Cycle can only ever follow one path.
False
Mechanical (physical) weathering
This place would have similar rocks to South America
Africa
The three types of plate boundaries.
Convergent, Divergent, Transform
To save or protect resources.
Conserve
Compaction and Cementation
What are the 5 agents of erosion?
Water, Wind, Waves, Gravity, Glaciers
Pangea
When two plates pass by each other, creating a fault line and earthquakes.
Transform boundary
The 3 R's of conservation.
Reduce, Reuse, Recycle
This type of igneous rock is described as "coarse-grained"
Intrusive Igneous Rock
Soil is primarily composed of these 4 main ingredients.
German scientist who created the theory of Continental Drift
Alfred Wegner
Lithospheric plates float on this layer of the mantle.
Asthenosphere
What resource is primarily used in the world to produce energy?
Fossil Fuels: Coal, Oil, Natural Gas
Metamorphic rocks that form with bands of alternating dark-light colors.
Foliated
The deposition of sediments in a fan-shape where a river flows into the sea/ocean.
What new theory explains how the continents move?
Plate Tectonics
When two ocean plates diverge, they create this feature.
Mid-Ocean Ridge.
The natural phenomenon in which heat is trapped by certain gases in our atmosphere, keeping our planet warm. Overuse of fossil fuels is causing it to increase unnaturally increase global temperatures.
The Greenhouse Effect
What processes create each of the 3 types of rocks?
sedimentary - Weathering, Erosion, Deposition, Compaction, Cementation
metamorphic - extreme heat & pressure
igneous - melting & cooling
Name the layers of soil and their horizon letters in order from top to bottom.
O - Organic Layer (Humus), A - Topsoil, B - Subsoil, C - Parent Material, R - Bedrock
Three pieces of evidence of continental drift
continents fit together, similar animal remains, similar rocks
Plate boundary that forms trenches and volcanoes
convergent (subduction)
What consequence can we expect on shorelines if sea levels increase due to global climate change?
Increased wave erosion. (Will also accept flooding)
