The earth's continents in the past were originally one huge continent known as pangea. However convection currents and the force of gravity caused this single giant continent to split into a series of separate tectonic plates which moved and split away from each other, ultimately resulting in the position of the continents we know today. If this continues (and there is no reason to think it won't) then the position of the continents will continue to shift, new oceans will form (this has already started in the East African rift which will over 100's of millions of years eventually form a new ocean) and continents will collide forming new mountain chains.
What else can I help you with?
Tectonic plates are present on the earths surface because what?
If we didn't have tectonic plates nothing would be living. We would have been burnt by the moulten lava
How does volcanos change the earths surface?
volcanoes change the earths surface due to the lava set hard and drys which can make the surface bobbly and ruff also it makes the land more fertilekill people
Why does the earths surface look the way it does?
The Earth's surface looks the way it does because of the way the wind, water, and the tectonic plates move under the surface. They have shaped the surface into what it is today through millions of years of change.
What are moving pieces under the earths surface that form the earths crust?
Tectonic plates are the moving pieces under the Earth's surface that form the Earth's crust. These plates float on the semi-fluid asthenosphere and interact with each other through processes like subduction, spreading, and collision, which contribute to the shaping of Earth's surface features.
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 forces below earth surface shape landforms?
The tectonic plates below earths surface shape earths landforms
Why you have an earthquake?
the tectonic plates are shifting under the earths surface.
What moves the ocean floor?
the tectonic plates under the earths surface
What are most earthquakes cause by?
moving tectonic plates on earths surface
Do tectonic plates cover the earths entire surface?
94% of the earth. yes
How do covergent boundary plates affect earths surface?
The tectonic plates combined together
What processes do scientist infer to have shaped earths surface in the past?
The shifting of Tectonic Plates.
What effect do sea floor and subduction have on earths surface?
They both can change the size of Earths Surface
What part of earths surface involves both chemical and physical change?
what involves both chemical and physical change on earths surface
What causes volcanoes to erupt under earths surface?
mostly earthquakes or plate tectonic movement.
Tectonic plates are present on the earths surface because what?
If we didn't have tectonic plates nothing would be living. We would have been burnt by the moulten lava
How do avalanches change the earths surface?
