How do heat and pressure change sedimentary rock?
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
What is a rock always?
A rock is always formed by heat and pressure it always starts out with heat and pressure......
How does igneuos rock get changed into metamorphic rock?
Heat and Pressure.
When sedimentary rock is exposed to heat and pressure's what does it change into?
Metamorphic rock
Sedimentary rock is converted into metamorphic rock with the addition of .?
Heat energy
What type of rocks expand?
All rock can expand or contract.
Does a rock expand or has contact with an increase in heat?
It expands because the atoms start to move faster from the energy of heat. :) :) :) <3 YOUR WELCOME !!
What has to increase for metamorphic rock to occur?
You need to increase heat and / or pressure for a metamorphic rock to form.
What does heat do to a rock?
At high temperatures, the minerals in a rock can change to other minerals. And, of course, rock can melt.
How the sun's heat breaks down rocks?
Heat: non-uniform thermal expansion. If you heat a rock in one area, thermal expansion causes the volume to expand locally. Since the adjacent rock is not heated, the expanding volume of rock has nowhere to go (no room to expand.) Pressure builds, and the rock eventually fractures
What do changes in temperature cause rock to do?
Changes in temperature cause rock to expand and contract. This may cause them to crack, and pieces may break off.
Which of theses can cause the expansion and contraction of rocks due to weathering?
Warming during the day, will expand the rock. Freezing during the night, will contract the rock.
In which region of the Earth's interior does the heat increase to the point that rock can begin to melt?
In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?
Does rock expand when heated?
In heat, the atoms or molecules making up any substance (e.g. a rock) start to move faster, because they are gettting more energy from the heat. since they move faster, they are also able to vibrate (in the case of a solid) more, and so can get further away from the centre of the objext. This causes the illusion of expansion, although the mass of the object remains the same.
What causes metamorphic rock to change?
An increase in heat or pressure could cause further metamorphism.
What causes sun or forest fires to crack rock?
not 100% sure but I think it's that the rocks expand when they get hotter and then as the contract when they cool down cracks appear
How does rain help in the formation of soil?
the sun heats up rocks during the day so that they expand. at night, these rocks cool down and contract. since all the parts of the rock do not expand and contract at the same rate, this results in the formation of cracks and ultimately the huge rocks break up into smaller pieces.
