Weathering
This is the type of weathering that occurs in caves.
What is chemical weathering?
This is a thick layer of ice that forms over thousands of years in extremely cold climates.
What is a glacier?
This is the side of a stream meander that undergoes erosion.
What is the outside?
The amount of open space in soil.
What is porosity?
A change in elevation is called this.
What is relief?
In the alka seltzer lab, we determined how this variable affects the rate of weathering.
What is surface area?
This is the shape of a valley formed by a river.
What is V-shaped?
This is the general slope of the edge of a stream undergoing erosion.
What is steep?
This is the most permeable combination of size and sorting.
What is large and sorted?
The Catskills are classified as this type of landscape.
What is plateau? (Not mountains!!)
This type of physical weathering occurs because of water's unique ability to expand upon freezing.
What is frost wedging?
This agent of erosion is responsible for forming cliffs.
What are waves/wave action?
When a stream is moving in a straight line, the stream bed is shaped like this.
What is symmetrical?
This variable affects porosity.
What is sorting?
Landscapes are classified by these two factors.
What is bedrock and elevation?
Because limestone contains this mineral, it will undergo chemical weathering in the presence of acid rain.
What is calcite?
These are large boulders that were carried by glaciers and deposited in a different location when the glacier melted.
What are glacial erratics?
This is the reason why deposition occurs on the inside of a river bend.
What is slow moving water?
The ability of water to move upwards through small openings.
What is capillarity?
This feature is responsible for the valley between the Catskills and the Adirondacks.
What is the Mohawk River?
This is the process where carbon dioxide in the atmosphere mixes with water to create carbonic acid - which reacts with some rocks and causes them to dissolve.
What is carbonation?
These features form once a river has meandered so far that two sides connect and form a shortcut, cutting off a whole section of the river.
What is an oxbow lake?
The fastest water velocity in the Hudson River can be found here.
What is the middle?
When water permeates soil, and some water molecules get stuck on the sediments and do not flow through.
What is retention?
In Australia, an oxbow lake is called by this other name.
What is a billabong?
