Continents are made up of various types of rocks, including sedimentary, igneous, and metamorphic rocks. Rock formations like Uluru are a result of geological processes that occur over millions of years, including erosion, weathering, and tectonic movements. The unique geological history of each continent contributes to the formation of distinct rock features like Uluru.
Approximately 30% of the Earth's surface is covered by land, the remaining 70% of the surface is covered by water.
The concept of continental drift is associated with the movement of continents across the Earth's surface over geological time. It explains the shifting of landmasses and the formation of oceans and mountain ranges. The theory of plate tectonics provides a framework for understanding and studying this process.
The continental drift hypothesis, proposed by Alfred Wegener, is the idea that Earth's continents were once joined in a single landmass and have since drifted apart. This movement of continents can affect sea levels by changing the distribution of land and water on Earth's surface. For example, if continents move closer together, it can create shallow seas and cause sea levels to drop, while if continents move apart, it can lead to the flooding of continental shelves and a rise in sea levels.
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.
The evidence that the continents are moving today is actually just a theory, but is accepted to be true. This theory is known as Continental Drift and is described as the continents belonging to tectonic plates, which are basically floating on the Earth's surface. Evidence to prove such is that the continents all fit together like a jigsaw puzzle and related or the same plant or animal species are located on separated continents, suggesting that they were all once connected to allow the animals to roam and the plants to spread. If they have moved in the past, they must still be moving today, and there are projected paths the continents are taking.
Matching geological formations across continents. Fossil evidence of similar species on different continents. Similar ancient climates and rock formations across continents. Fit of the continents like puzzle pieces on the Earth's surface.
Days, seas, and continents are all natural cycles or formations that occur on Earth. Days are the cycle of light and dark caused by the rotation of the Earth, seas are large bodies of saltwater that cover a significant portion of the Earth's surface, and continents are large land masses that make up the Earth's surface.
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.

Continental drift is the theory that the Earth's continents have drifted apart from a single landmass known as Pangea over millions of years. This movement is due to the shifting of tectonic plates on the Earth's surface. This theory is supported by evidence such as the matching coastlines of continents, similar rock formations, and fossils found on different continents.

No, I don't think so.
Rocks help support the theory of continental drift through evidence such as similar rock formations and fossils found on different continents, matching up when the continents were once part of the same landmass. Additionally, the alignment of magnetic minerals in rocks provides further evidence of past positions of continents as they moved over the Earth's surface.
Continents cover about 29% of the Earth's surface area. The rest of the surface is predominantly ocean.
