Question and answer
9. How do we know that tectonic plates move?
Plate tectonics is a scientific theory that describes the large-scale motions of Earth's lithosphere. The theory builds on the concepts of continental drift, developed during the first decades of the 20th century. [ It was accepted by the geoscientific community after the concepts of seafloor spreading were developed in the late 1950s and early 1960s. ]

User: Describe how transform plate boundaries differ from plate boundaries.

User: What form of geologic activity is exhibited along transform boundaries?

User: 10. On what tectonic plate do you live?

Weegy: Tectonic plates are pieces of the Earth's crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km thick and consist of two principal types of material: oceanic crust and continental crust . The composition of the two types of crust differs markedly, with basaltic rocks dominating oceanic crust, while continental crust consists principally of lower density granitic rocks.




User: In which direction are these plates moving?

Weegy: Plating carrier (plural plating carriers) (aviation, travel industry) The airline that a ticket has been issued on behalf off. [ Etymology from the plates, shaped like a credit card with a raised airline name, formerly used when paper tickets were issued. ]

User: 4. How are comets different from asteroids?

User: 3. Describe the “big splash” theory of the Moon’s origin?

Weegy: The fourth theory is the one that most scientists currently believe is correct. It states that when the Earth was quite young, a Mars -sized planet crashed into it. [ The planet crashed with such speed that it was completely destroyed, and almost destroyed the Earth. The planet was coming in with such force that when it was destroyed, the molten iron in its core continued to travel through Earth, to eventually be included it its core. This explains why the Moon has very little iron. The crash, comically dubbed the "Big Splash," sent tons of rock and debris into orbit. These fragments eventually coalesced to form the Moon. The tidal and rotational forces in play also account for why the moon's day is exactly the same as it's "year." ]
