What do continental plates float on?
Continental plates float on the partially molten layer of the Earth's mantle called the asthenosphere. This layer is composed of solid rock that can flow slowly over long periods of time, allowing the plates to move on the Earth's surface. The movement of the plates is driven by the heat and convection currents within the mantle.
Is the moving portion of earth's crust and upper mantle called a ridge?
No, the moving portion of Earth's crust and upper mantle is not called a ridge. It is known as the lithosphere, which consists of the outermost layer of the Earth that is divided into several large plates that shift and move over the underlying asthenosphere. A ridge refers to a long, narrow elevation on the Earth's surface, commonly found at divergent plate boundaries where new oceanic crust is formed.
Why are tsunamis in the world?
this happens when the earth's tectonics plates have rubbed together for a long time on a fault line over a long time this pressure builds then suddenly releases and this a displacement of water ties to spread out, and this causes tsunamis it they happen to reach land and they are big. This is what I learnt
Why does the ocean plate and the continental plate move against each other?
The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.The plates are made of rock and drift all over the globe; they move both horizontally (sideways) and vertically (up and down). Over long periods of time, the plates also change in size as their margins are added to, crushed together, or pushed back into the Earth's mantle. These plates are from 50 to 250 miles (80 to 400 km) thick.Oh and if you want to know how to make things huge: go to power point and copy down what you want then copy and paste.
What is the long crack that forms as two tectonic plates move apart?
The long crack that forms as two tectonic plates move apart is called a rift. It is typically seen in divergent plate boundaries, where the plates separate and magma from the mantle can rise to create new crust. Over time, as the plates continue to move apart, the rift can widen and eventually lead to the formation of a new ocean basin.

Where is the rocky mountains located and how do they form?
the rocky mountains are located in North America. A long time ago, there was one big continent on the planet earth and soon enough, it drifted apart into plates. When those plates crashed together, they forced the earth's crust to go up, and over time the plates were pushed together so much, it forced them really high and they formed the Rocky mountains.
What is long crack where plates diverge?
Itis called a rift.
Long deep cracks formed when plates separate?
rift vally on land, and mid-ocean ridge under water
How was the earth spilt into different continents long time ago?
The theory of plate tectonics explains that Earth's lithosphere is divided into large plates that move and interact with each other. Millions of years ago, these plates were once all connected as one supercontinent called Pangaea. As the plates moved and shifted over time, Pangaea broke apart, leading to the formation of the continents we see today.

What is the cause of the currents that make plates move across the earth?
The currents that drive plate movement are caused by the heat generated from the Earth's core. This heat creates convection currents in the mantle, which in turn move the tectonic plates on the Earth's surface.
What is the thick layer under the crust?
The thick layer under the Earth's crust is called the mantle. It is made up of solid rock that can flow slowly over long periods of time. The mantle is responsible for driving the movement of tectonic plates on the Earth's surface.
What are long cracks in the earth's crust called?
It's called a "fault"
Thick layer of earth that extends downward from the crust to the core?
The thick layer of earth that extends from the crust to the core is called the mantle. It is composed of solid rock that can flow slowly over long periods of time. The mantle plays a crucial role in the movement of tectonic plates and the geologic processes of the Earth.
What is the one area that bones do not fuse together?
The one area where bones do not fuse together is the growth plates, also known as epiphyseal plates. These are cartilaginous areas at the ends of long bones that allow for bone growth during childhood and adolescence. Once a person stops growing, the growth plates ossify and the bones can no longer grow in length.
