What does plate tectonics mean?
It's a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
What are the earths plates floating on?
The surface of the Earth is divided into roughly 30 separately distinct units called plates. Each individual plate is separated by a fault, and each plate moves independently of every other plate. The movement, or float, of the lithospheric plates is caused by heat from the Earth's interior, which causes convection currents in the Earth's mantle, a layer of solid but movable plastic-like rock. The movement of Earth's lithospheric plate which 'float' on the mantle is very slow in human terms, roughly the rate of fingernail growth, but over millions of years, the change in plate locations is dramatic.
Why do the continents and ocean floors move?
Although it seems impossible, the continents and sea floor form a series of plates that float on the Earth's mantle. The mantle is heated form below (the core of the Earth is molten) and this causes the mantle to convect (like a boiling pan of thick soup). The convention happens only very slowly but as it does it moves the surface plates about. The plates move at about the speed your fingernails grow.
Why cant the tectonics plates move without affecting another plate?
it is because when like the tectonics move slowly the tectonic is like
What makes a fault happen?
Faulting occurs when there are two tectonic plates that meet at a divergent boundary. This means that they move away from each other. The general reason of why plates move is because of a gently rolling mantle. The rock in the mantle is just liquid to flow like taffy. This extremely slow movement, also slowly moves the tectonic plates. Once again, at divergent plate boundaries the plates move away from each other. Without a sudden movement of the plates (such as an earthquake) this process will only enlarge the fault cm a year.
How are lithospheric plates like shopping carts?
lithosperic plates are like shopping carts because because it shows the movement of the plates and there are small wiggles between each cart
How can you describe the seven crustal plates?
There are actually at least 31 identified lithospheric plates, the plates consisting of crust and uppermost mantle which float on top of the plastic-like asthenosphere of the mantle.
What are converging boundaries?
A convergent boundary is when two plates collide with each other forming landforms like trenches, or mountains (depends which type of plates converge.)

Do tectonic plates 'float' on the surface of the mantle?
The tectonic plates (the lithosphere) are made of the crust and upper brittle part of the mantle. They 'float' on the hotter and softer mantle below, which is still a solid, but can flow like plasticine (the asthenosphere)
What is a section of the lithosphere that slowly moves over the asthenosphere carrying pieces of continental and oceanic crust?
Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. The lithosphere is broken into giant plates that fit around the globe like puzzle pieces.

How does a seahorse moves slow or fast?
Slowly. Their tinly little fins will flap like crazy, but the seahorse will move slowly through the water.

What are plates composed of?
A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of the continental and oceanic crust. A plate is part of dinnerware that is flat as opposed to round like a bowl.
