What is chemical weathering?
When moisture/water mixes with chemicals in metal to make them rust/tarnish.
100
This is what we call uplifted land that results from two tectonic plates colliding.
Mountains.

Describe how ice wedging works.
Water seeps into cracks of rock and freezes overnight, causing the ice to expand and crack rock.
200
This is a mound / hill of windblown sand.
Dune
200
A "v-shaped valley"
Canyon
200
What is a basin?
A low lying area where sediment / water is deposited.
200
This is what we call a "gently sloping shore next to a body of water washed by waves or tides, often covered by sand or pebbles."
Beach

Describe a plateau. **DAILY DOUBLE**
A flat, uplifted area of land.
300
Humans create these to help them understand and test how the universe works.
Models.

What are lichen?
They are a type of moss that chemically erode rocks.
300
What is a sedimentary rock?
A rock composed of many different sediments.
300
This is "nature's glue" to help lithify sedimentary rocks.
Matrix

What is a delta?
A fan-shaped deposit at the end of a river.
400
This vocabulary word describes "a sequence of rock layers that comprise of more than one rock type." **DAILY DOUBLE**
Formation
400
When viewing a cross-section of rock, this important geological principal states that in many cases, the deeper rocks are older than the rocks above. What is this called?
The Law of Superposition
400
This vocabulary word refers to the process of matching up rock layers.
Corellation
400
Understanding the present helps us better understand the past.
The Principle of Uniformitarianism

What is the main difference between weathering and erosion?
Weathering = Breaking apart of rocks
Erosion = The removal of rock/sediment
500
This is the word to describe a curve or loop in a river.
Meander
500
This process refers to the creation of new sedimentary rocks.
Lithification
500
This is the name for the area of land around a river that is usually covered in water after heavy rainfall.
Floodplain
500
Describe how deposition works using at least one other vocabulary word.
Water runs over a flat surface (such as a plateau), carves out a canyon and deposits sediment into a delta at the edge of a plateau.
500
What is a visual difference between a clastic and non-clastic rock?
Clastic rocks are composed of many different color/size particles that are lithified (such as conglomerate)
Non-clastic rocks are composed of mainly one type of sediment (such as sandstone)
