What rock makes up the continental crust?
The continental crust is made up of igneous, sedimentary, and metamorphic rocks. These rocks form the continents and the continental shelves, areas of seabed close to the shore.
The continental crust is what?
Composed mostly of granite, the continental crust is the layer of igneous, sedimentary, and metamorphic rocks which forms the continents and the areas of shallow seabed close to their shores, known as continental shelves
What type of rocks are found in a continental shelf?
The rocks found in a continental shelf are often sedimentary rocks, such as sandstone, shale, and limestone. These rocks are formed from the accumulation of sediments on the ocean floor over long periods of time. Additionally, some continental shelves may also have igneous rocks brought up from volcanic activity.
How might the continental shelf be affected if you had another ice age?
When there is another glaciation, water from the oceans will be locked up on land as ice. This will cause the sea levels to go down and more of the continental shelves will be exposed above sea level.
How do wetlands protect shorelines from erosion?
By virtue of their place in the landscape, riparian wetlands, salt marshes, and marshes located at the margin of lakes protect shorelines and streambanks against erosion.Wetlandplants hold the soil in place with their roots, absorb wave energy, and reduce the velocity of stream or river currents.
What rock is continental plates made up of?
Continental Crust is the layer of rocks that forms the continents and continental shelves. It is mostly made of granite or granitic rock.
Does sediment build up at the continental shelf?
The continental shelves were formed millions of years ago, when most of the land on the Earth was compacted into one huge landmass. After some time, this landmass began to break into smaller pieces, which became the continental shelves. Then they drifted farther and farther apart and appear where they are today.
How do continental shelves form?
The continental shelves were developed in between the glacial periods as the ocean flowed over the continents forming shallow areas along the coasts. The continental shelves developed today were formed like 18000 years ago.
What are the shallow fringe water up to about 180 m deep bordering the continent known as?
They aare called continental shelves
What rock makes up the continental crust?

The continental crust is what?
Composed mostly of granite, the continental crust is the layer of igneous, sedimentary, and metamorphic rocks which forms the continents and the areas of shallow seabed close to their shores, known as continental shelves
What is the maximum weight the shelves can hold?
These shelves have the capacity for holding up to 30 pounds.
How are shorelines formed?
Shorelines are formed through a combination of erosional and depositional processes. Erosion from water and wind wears away the land, while sediment carried by rivers and currents can be deposited along the coast, gradually building up shorelines. Tectonic activity, sea level changes, and weather patterns also play a role in shaping shorelines over time.
The five larges lakes are located?
Caspian Sea: has an area of 371,000 km2 (143,000 sq mi); makes up the shorelines of Kazakhstan, Turkmenistan, Iran, Azerbaijan, and Russia.Michigan-Huron: has an area of 117,702 km2 (45,445 sq mi); makes up the shorelines of Canada and the United States.Superior: has an area of 82,414 km2 (31,820 sq mi); makes up the shorelines of Canada and the United States.Victoria: has an area of 69,485 km2 (26,828 sq mi); makes up the shorelines of Uganda, Kenya and Tanzania.Tanganyika: has an area of 32,893 km2 (12,700 sq mi); makes up the shorelines of Burundi, Tanzania, Zambia and the Democratic Republic of the Congo.

Which coastline of continents seem to match up like puzzle pieces?
The east coast of South America and the west coast of Africa appear to match up like puzzle pieces. This phenomenon is known as the "Atlantic Puzzle" and is evidence of the theory of continental drift.
How do you adjust shelves of ShelfTech Systems shelves?
Gently raise shelf up and then separate the black small plastic pcs. Raise them up or down as needed and then pull the shelf unit back down over the plastic pcs. The friction crimps around the plastic pc and it holds.
