What else can I help you with?
Which term describes the point on the earth surface above the area where an earthquake originated?
The term that describes the point on the Earth's surface above the area where an earthquake originates is it's epicenter.
What type of rock developed the first proto-continents?
Igneous rock was the first rock to cool on the surface.
Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle
What term describes magma that flows out onto earths surface?
Lava ;D
What is the evidence missing from Alfred Wegener's continental drift theory?
The only evidence that Alfred Wegener did not have was the mechanism that drove the Continental Drift, he had evidence to support that the continents were once joined together, but did not have the means to postulate how the continents had actually moved to their present positions. He did however postulate the theory of a "layered Earth" consisting of a rigid surface (continents) upon a liquid/plastic like substance (mantle) and that if pressure was exerted on the surface layer, it would move thus, and if the pressure was removed the surface would return to its original state. It was only until c. 1890, when the Geophysicist Arthur Holmes came up with the theory of convection currents in the mantle being responsible for Continental Drift.
If continents continue to drift is it possble that a new super continent will form?
Yes, it is possible for continents to drift together and potentially form a new supercontinent in the future. This process is known as continental drift, and throughout Earth's history, supercontinents like Pangaea have formed and broken apart. The movement of tectonic plates continues to shape the Earth's surface over millions of years.
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.
How much of the Earth's surface do the continents cover?
Continents cover about 29% of Earth's surface. The rest is mostly covered by oceans.
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.
Idea that continents move on Earth's surface?
The idea that continents move slowly across the earth's surface is called the continental drift.
What percentage of the Earth's surface is occupied by the continents and islands?
Approximately 29% of the Earth's surface is occupied by the continents and islands. The remaining 71% is covered by oceans.
Contrast the continents of Venus with those of Earth?
Venus only has two continents and they occupy about 8 percent of the surface. Earth's continents occupies about 25 percent of the surface. Venus also does not have any evidence of plate tectonics.
How can the earth's surface be organized into continents and oceans?
the earth can be organized into 4 oceans, 7 seas, and 7 continents
How can water hold the continents?
The continents are not floating on water, if that is what you mean. The large bodies of water on the earth's surface fill up some of the spaces between the continents.
What is the surface of the planet that forms the continents and ocean floor?
The crust.
How long has the surface on earth been changing?
for as long as it has had continents
What percentage of the earth surface is covered by continents?
25 I guess.
