What is a continental shift?
A continental shift refers to the movement of continents on the Earth's surface due to plate tectonics. This movement is very slow, occurring over millions of years, and can result in changes to the configuration of the continents and the ocean basins. Examples of continental shifts include the breakup of Pangaea into the continents we see today.
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 is a tectonic plate in 6th grade science?
Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other. These plates cover the Earth's surface and are responsible for the formation of continents, ocean basins, and geological features like mountains and volcanoes. The movement of tectonic plates can cause earthquakes and volcanic eruptions.
What is the slowest to change earths surface?
The slowest-changing feature on Earth's surface is likely its tectonic plates, which move at a rate of a few centimeters per year. This movement can result in slow changes in topography and the creation of mountains or ocean basins over millions of years.
What divides the global oceans?
The global oceans are divided by continental land masses into the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic oceans. These divisions are based on the geography of the Earth's continents and the interconnectedness of the ocean basins.
Does the earths crust extend deeper below the continents or below the ocean basins?
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
what are the two divisions of earth's surface?
Ocean basins and continents
What are Mountains and basins?
A mountain is a natural, large elevation in the Earths surface. A basin is a depression in the Earths surface containing water.
What are the two principal division of earth's surface?
Ocean basins and continents
What are the two principal divisions of Earth's surface?
Ocean basins and continents
Are most plates boundaries continents or in ocean basins?
In ocean basins
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.
What part of earth is the continents and ocean basins?
crust
How do continents affect surface currents?
Continents can block the flow of surface currents, creating barriers that deflect the currents in different directions. They can also influence the direction and speed of currents by shaping the coastlines and creating deep ocean basins that can channel currents. Additionally, continents can impact the distribution of heat and moisture, which can affect the intensity and direction of surface currents.
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 process is responsible for moving rock materials from the continents into the ocean basins?
Erosion.
