It's only soft and plastic in that it is not as hard as the brittle rock of the crust and uppermost mantle which comprises the lithosphere (which comprises the continental and oceanic plates). Mostly composed of solid rock, nearly 5% of the upper mantle (asthenosphere) is molten. It doesn't sound like much, but it's enough to allow the rock to behave in a highly viscous manner; in other words, in can bend and move without breaking. The heat being generated from the interior of the Earth causes convection currents in this layer of the mantle. Rock rises slowly toward the surface at divergent plate boundaries, moves laterally causing plate movements (there is some disagreement here among scientists on the cause and effect relationship) and sinks back into the depths of the mantle when it has cooled and become more dense. At greater depths, the mantle is more solid, as the pressures become too intense for melt to occur.

What does the term plastic mean when describing the upper mantle?
When describing the upper mantle, the term "plastic" refers to the ability of the mantle material to deform and flow over long periods of time under high temperatures and pressures. This plastic behavior allows the mantle to flow and convect, driving plate tectonics and other geological processes.
What does asthenoshere mean?
the answer is the solid , but plastic layer found in the upper mantle ................hope this helps bye bye .
What if mantle were rock what feature would not form on earths surface?
If anything is rock-solid, it will result in a flat landscape. This will mean that there will be no plateaus, deep sea trenches, volcanoes or mountains if the mantle were solid rock.
What does lithosphere mean in science terms?
The lithosphere refers to the rigid outer layer of the Earth, comprising the crust and part of the upper mantle. It is divided into tectonic plates that float and move on the semi-fluid asthenosphere underneath. The lithosphere plays a crucial role in plate tectonics and the formation of Earth's surface features.
Does lithosphere and asthenosphere mean terms differ?
Yes. The lithosphere consists of the uppermost layers of Earth: the crust and the rigid portion of the mantle. The asthenosphere is the layer below the lithosphere, consisting of rock with a plastic texture.

What does the earths moon mean?
the earths moon helps sustsian the gravity on the earths oceancs keeping them in balance
What does pass the mantle mean?
The passing of the mantle, means passing power from one person to another.
What does it mean if a rock is like plastic?
Plastic-like rock is found in the asthenosphere, the layer of Earth directly beneath the crust and uppermost mantle. Though consisting of hard rock, the high temperatures and inclusion of a small amount of molten material allows the rock to behave in a plastic-like manner; that is, it can be moved and bent without breaking.
Why would plastic be considered a renewable resource?
usually old plastics are dirty there is a lot of bacterias that are left in the plastic. by recycling the plastic, the recyclers can clean those plastic, by melting it and make a new plastic again and they reuse it back.
In 6th grade what does mantle mean?
middle of the Earth
What does unplasticized mean?
The thing has no plastic in it, not made out of plastic, or has nothing to do with plastic at all.
What does thermo setting plastic mean?
a plastic that has aids :)
