Weathering
Ice Wedging
caused by substances that get into holes and cracks in rock and expand outwards. This exerts pressure on the rock and may cause it to further crack and split apart. Water that freezes in cracks and forms ice, salt from evaporated seawater, and growing plant roots may all cause wedging.
What type of erosion formed the Grand Canyon?
Moving water/River
How do sand dunes form?
These dunes are created by the wind. The wind will pick up the sand from one location and carry it to another dune where it will settle down.
What are the 4 types of Mass Movement?
Landslides
Mudflows
Slump
Creep
What is weathering?
The physical breakdown or chemical decomposition of rock materials exposed at Earth's surface.
What is Erosion?
5 POINTS!!!!!!!!!!!!!!!!!!!!
the movement of weathered material to a new location
What is responsible for the formation of sand dunes?
Wind
What does Florida's bed rock mostly consist of?
Limestone
What is a landslide?
When rock and soil slide quickly down a steep slope. These may contain huge amounts of rock or very small amounts of rock and soil.
Physical weathering
The process by which rock is broken down into smaller pieces by physical means.
Water
Ice
Wind
Gravity
How do Deltas form?
When a fast moving river meets a large ocean, the water (and whatever the water is carrying) will stop very quickly. The sediment will settle to the bottom and eventually create small landforms
What is a mudflow?
A mudflow is the rapid movement of water, rock and soil. They often occur during heavy rains. Clay in the soil will actually act like a liquid as it begins to flow like a river.
Chemical weathering
Breakdown of rocks through chemical means.
Moving water
What is Deposition?
The dropping off of sediments in a new place.
What is are Everglades? (How did it Form)
5 POINTS!!!!!!!!!!!!!!!!!!!!
A large wetland that covers several thousand square kilometers. It formed on a flat block of limestone that tilts to the south. This allows water to flow from Lake Okeechobee to Florida Bay
What is Slump?
Slump is a type of mass movement where a mass of rock and soil suddenly slip down a slope. Unlike a landslide the materials in a slump move down in one large mass.
Acid Rain
caused by sulfur and nitrogen compounds in the air reacting with water to form acids that then fall to the ground. These acids are particularly harmful to marble, chalk, and limestone, and cause damage to tombstones, statues, and other public monuments.
Which erosion agent is used to develop a creep?
glaciers
oxidation
gravity
wind
3 examples of deposition?
Waves dropping off sand on the beach
Formation of Sand dunes
Formation of Deltas
What is Creep?
often results from freezing and thawing of water in cracked layers of rock beneath the soil. It is so slow the effects is seen in vertical objects such as telephone poles and tree trunks
Abrasion
Caused when rocks rub together. For example, the rocks on a riverbed smooth each other because they collide in the current. Small particles of rock carried by the wind may cause abrasion as well.
Which landform is formed because of the erosion of groundwater?
valley
cavern
canyon
channel
Weakest form of Deposition
Wind
How is Limestone built?
Ocean-dwelling organisms such as oysters, clams, mussels and coral found in seawater (shells and bones). The water pressure compacts the sediment, creating limestone.
What causes all mass movement?
Gravity
