There called tectonic plates, and they do not float on anything.
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.
rigid
The Earth's crust and the uppermost part of the mantle together form the lithosphere. The lithosphere is a rigid outer layer of the Earth that is divided into tectonic plates which float on the semi-fluid asthenosphere beneath them.
The earths crust is split into large pieces called plates. When they move they cause a earthquake.
The tectonic plates which form Earth's crust move on top of the outer layer of the mantle. This layer of the mantle is known as the asthenosphere.
Tectonic plates are floating on the magma (semi-molten rocks) of the mantle layer. Therefore, they form the crust layer of the Earth.
majority of valcanoes follow the edges of the tectonic plates, which are the weaker parts of earths crust, therefore volcanoes form durin the crust giving away to the pressure built up. other volcaoes form other places due to weak parts of earths crust
At breaks in the earths crust; like the tectonic plates; an earthquake can trigger a volcano, and depending on what kind of volcano it is, it can form a mountain.
Folds in the Earth's crust primarily form on convergent plate boundaries where tectonic plates collide. The immense pressure and stress from the plates' movement cause the rocks to deform and bend, resulting in fold formations.
It depends on the type of plates coming together but two continental plates will form a mountain chain. An example would be the Indian sub-continent colliding with Asia to form the Himalayas.
The rigid crust and uppermost mantle form the Earth's lithosphere. This outermost layer is divided into large pieces called tectonic plates that float on the semi-fluid asthenosphere below. The interaction of these plates is responsible for shaping the Earth's surface through processes like earthquakes and mountain formation.
alright so when tectonic plates meet there are earthquakes because when the plates collide with each other because the earth is always moving it creates giant earthquakes that push and pull the tectonic plates on the crust of earth causing earth quakes. Volcanoes form at the boundaries of tectonic plates because it is one of the only places on the earths crust where there are holes in the crust so the liquid mantle (lava) can escape through the earths crust. forming volcanoes.
