100
The three main types of sedimentary rocks.
What are Clastic, Biological, and Chemical
100
The type of biological weathering in which a plant's roots break apart a rock.
What is root wedging?
100
These cave features are found clinging to the ceilings of caves.
What are stalactites?
100
This is the amount of water on Earth?
What is 72%
100
This type of fossil is includes a piece of an organism such as teeth, leaves, bones, etc.
What is a body fossil?
200
This sedimentary rock is made of lithified crushed up and fossilized shells.
What is Coquina?
200
The name of this feature correlates to its shape and is formed by what?
What is a v-shaped valley formed by river erosion?
200
The type of rock that karst typically forms in.
what is limestone?
200
This is the major watershed of Virginia that we live in.
What is the Chesapeake Bay Watershed?
200
This is the cavity in a rock made when an organism decayed.
What is a mold?
300
The process called in which sediment is squeezed by overlying material.
What is compaction?
300
These two processes formed the cutbank and pointbar shown in the image.
Cutbank: Erosion
Pointbar: Deposition
300
The geographic province of Virginia that is abundant with karst topography.
What is the valley & ridge province?
300
Describes how easily water can pass through sediment grains.
What is permeability?
300
This type of fossil provides evidence of an organisms behaviors and typically includes footprints, burrows, feces, and eggs.
What is a trace fossil?
400
the process in which minerals in water act like glue to stick sediment grains together.
What is cementation?
400
This triangular feature is formed by which process?
What is a delta formed by deposition?
400
The type of weathering that is primarily responsible for the development of these caves.
What is chemical weathering (specifically dissolving of limestone)?
400
A body of permeable rock which can contain or transmit groundwater. They are responsible for providing water to homes.
What is an aquifer?
400
This rock layer appears to be most resistant to weathering and erosion.
What is the lockport dolostone?
500
This rock is composed of angular clasts of gravel that have been compacted and cemented together.
What is Breccia?
500
This process moves fragments of rock and soil through water, ice, wind, or gravity.
What is erosion?
500
The chemical compound that is formed as water infiltrates soil to weather the limestone and produce karst features.
What is carbonic acid?
500
These locations have the saltiest ocean water (explain why).
What is the poles and equator. Because as water freezes and evaporates, it leaves the salts behind.
500
This rock shows evidence of being transported the farthest distance by a stream.
What is the bottom left rock
