Weathering
The process that breaks down rock and other substances at earth’s surface.
What is weathering?
The process by which natural forces move weathered rock from one place to another.
What is erosion?
The rock cycle usually begins with a _______ _________.
What is volcanic eruption?
Name the two types of glaciers. Where does each of the glaciers form? Which is bigger?
What is a continental glacier and valley glacier?
Continental glacier forms on a landmass/continent - biggest type of glacier
Valley glacier forms in valleys between mountains
After an experiment has been completed, what must be done to the raw data?
What is analyze?
Ice wedging is a type of _________ __________. Explain how ice wedging occurs. Eventually, ice wedging causes a rock to completely _______.
What is mechanical/physical weathering?
Water gets into the crack of a rock, freezes, then causes the crack to expand. The water melts out of the crack then more water gets into the crack and freezes. This causes the crack to expand even more. Eventually the rock will break completely.
The dropping of sand on a beach by waves is an example of ___________.
What is deposition?
What are the three types of rock, how are they created?
What is:
Igneous - cooled lava
Sedimentary - layers of weathered igneous rock, dirt, or animals
Metamorphic - heat and pressure
_____ is sediment left behind by a glacier. Glaciers are ________ at a faster rate. Some scientists believe this is due to ________ __________.
What is till; melting, global warming?
What is the difference between repetition and replication?
What is repetition is the process of copying someone else's work; the process of replication is when someone repeats something they have already done?
Acid and oxidation are examples of this type of weathering. Oxidation is a fancy word for ________.
What is chemical weathering? What is rust?
When talking about various forms of weathering, agent means a _______. The primary agent of deposition is ________.
What is a cause; gravity?
When a volcano erupts, it is caused by _________ ________. Magma is ______ ______ that is located in the _______.
What is tectonic activity; liquid/molten rock; mantle?
The difference between plucking and abrasion. These are two agents of glacial __________.
Erosion
List the steps of the scientific method in order. A conclusion allows scientists to _____ or ______ their hypothesis or prediction.
What is:
Make observation/ask a question
Make a hypothesis/prediction
Experiment
Analyze data
Conclusion - accept or reject
This type of weathering causes the composition of rocks to change.
What is chemical weathering?
3 agents of physical erosion are:
What is animals, people, abrasion (wind, water, ice, sand, snow)?
Identify the three types of tectonic boundaries (you can also explain the movements). Which boundary results in the formation of mountains and volcanoes?
Convergent (move toward each other), Divergent (move away from each other), Transform (slide past each other).
Convergent boundary creates mountains and volcanoes
Two landforms glaciers create by erosion. Two landforms glaciers create by deposition.
What is a cirque and u-shaped valley?
What is moraine and kettle?
DOUBLE THE POINTS!
What are Newton's 3 Laws of motion?
What is an object at rest/in motion will stay at rest/in motion until an outside force acts upon it, force =mass x acceleration, for every action there is an equal but opposite reaction?
The growth of plant roots into rocks can result in this type of weathering. Why?
What is mechanical/physical weathering? Because pressure from the plant's growing roots cause the rock to crack and eventually break.
These three processes work together to cause changes to ________ ________.
What is weathering, erosion, and deposition; earth's surface?
What is:
Volcano erupts, lava cools, igneous rock forms
Igneous rock goes through W.E.D. and turns into sedimentary rock
Sedimentary rock gets heavy and sinks toward the mantle
Metamorphic rock goes through heat and pressure, turns back into magma
How are glaciers formed? How long does this process take?
What is:
Snow falls
Snow accumulates
Snow compacts
This process repeats for at least 100 years.
DOUBLE THE POINTS! Velocity measures the _______ and _______ of an object. Acceleration measures changes in an object's _______.
What is speed and direction; velocity?
