In ocean basins
What else can I help you with?
Are most plate boundaries on continents or in ocean basins?
Most plate boundaries are located in ocean basins rather than on continents. This is because oceanic plates are denser than continental plates, leading to subduction zones and mid-ocean ridges where most of the plate boundaries are found in the oceans.
What can divergent boundaries form?
A rift zone on land, a mid ocean ridge under the ocean.
From what landforms can divergent boundaries form?
Divergent boundaries can form along mid-ocean ridges, where tectonic plates move away from each other, creating new ocean crust. They can also form on continents, where rift valleys develop as plates pull apart, leading to the formation of new ocean basins.
How do the positions of the plates affect the positions of the continents?
The positions of the plates determine the movement and interactions of continents. Plates can converge, creating mountains and causing continents to collide. They can also diverge, leading to the formation of new ocean basins and pushing continents apart. Transform boundaries result in lateral movement of plates, affecting how continents slide past each other.
The change from pangaea to the present configuration of the continents involved?
The breakup of Pangaea involved the gradual drifting apart of the tectonic plates carrying the continents. This movement created new ocean basins and shifted landmasses to their current positions over millions of years. Today's configuration of continents is a result of this ongoing process of plate tectonics.
What is the theory that all continents are fragments of Pangaea now drifting apart?
The theory is known as plate tectonics. It suggests that the Earth's outer shell is divided into several large, rigid plates that move relative to each other. The movement of these plates explains the positions of continents and ocean basins and supports the concept of continental drift.
How do plates cause ocean basins?
the earth.
What part of earth is the continents and ocean basins?
crust
If Earths plates and continents are constantly moving what effect does this have on Earths oceans?
The movement of Earth's plates and continents can cause changes in sea level, ocean currents, and the distribution of marine life. It can also affect the shape of ocean basins and the location of coastlines.
Are the edges of continents are the same as the boundaries of plates?
No. Not all plate boundaries are at the edges of continents, nor do all edges of continents correspond with plate boundaries. Many plate boundaries are found in the middle of oceans, while the continent of Africa is being torn apart by a developing plate boundary. Some edges of continents, such as the west coast of South America are near plate boundaries. These are called active continental margins. Others, such as the east coast of North America, are nowhere near plate boundaries. These are called passive continental margins.
Are the continents and ocean basins located in the asthenosphere?
No, the continents and ocean basins are located on the lithosphere, which is the rigid outer layer of the Earth. The asthenosphere is a semi-fluid layer beneath the lithosphere.
what are the two divisions of earth's surface?
Ocean basins and continents
