What percentage of the earths surface do the continents represent?

Continents cover about 29% of the Earth's surface area. The rest of the surface is predominantly ocean.


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.


Why does the shape of the earth's oceans and continents continue to change?

The shape of the Earth's oceans and continents continues to change due to processes such as plate tectonics, erosion, and volcanic activity. Plate movements reshape the continents and ocean basins over millions of years, while erosion from water and wind constantly alters the landscape. Volcanic activity adds new land and changes the topography of the Earth's surface.


Some scientists theorize that continental movements may cause climate changes by?

Ok, so the movement of the continents changed location of land and sea, therefore changing the wind patterns and ocean currents, slowly changing climate globally. Also, as the continents continue to move, climates will also continue to change.

What does the shape of the continents tell us?

The shapes of the continents gives us an insight into earths past and history.When tried to arrange they seem to fit in like a "Jigsaw puzzle".This tells us that there was once a time,aeons of years ago when all continents were together as one "Super continent",but were separated by "Drifting",reshaped and sculptured by agents of "Denudation".


How much of the Earths surface is covered by the continents?

Approximately 30% of the Earth's surface is covered by land, the remaining 70% of the surface is covered by water.
