Are metamorphic rocks formed by some combination of heat pressure and mechanical activity?
Metamorphic rock can be formed a a combination of heat, pressure, and mechanical activity, or by heat, or by pressure from a mechanical activity such as plate motions.
What can granite and shale form under heated pressure?
Some shale becomes limestone and some changes into coal depending on what minerals are in them. --http://library.thinkquest.org/05aug/00461/shale.htm
What is the order of hardness for Granite Limestone and marble?
Using Mohs scale of hardness for minerals, you can--with a bit of detective work--find out the hardness of Granite, Limestone and Marble.But I think that we can do a bit of reasoning and figure out for ourselves the order of hardness for these stones.First off, knowing that Limestone is a sedimentary stone, Granite is a metamorphic stone and Marble is igneous stone, can give you some idea how these stones measure against each other in hardness.Alright, sedimentary stone is laid down, layer on top of layer, until it compresses enough to create a stone. Then igneous stone is created by magma being cooled and becoming a solid stone. Metamorphic stone is changed--with pressure and heat, creating a metamorphosis to another stone entirely.Thinking how each of the stones, which do you think would be the softest, the hardest, then the one left would be between the two others.I would deduct that Limestone would probably be the softest, as it is layer upon layer--not really going through much change or pressure to become Limestone. Now, to figure out which of the two left over might be the hardest. I would suggest the stone which has gone through the most heat and pressure would be the hardest. The stone which qualifies as the most changed, would be the metamorphic rock, Granite. What you have left over, is the igneous rock, Marble. To check if that truly would be the middle hardness, it was created with heat, which would be more "processing" than just layered like Limestone, but wasn't as "processed" as heat AND pressure as Granite was. So it appears that Marble would fit between Limestone as the softest, and Granite as the hardest.Now you have deduced how to determine the order of hardness between Limestone, Marble and Granite.
When did granite form?
Granite forms underground and may take millions of years to cool from a state of magma to a solid rock. Some granites are billions of years old, and some granite is forming as you read these words.
What is the coldest out of granite marble and stone?
That depends on the ambient temperature, among other things. If you have two lumps of stone in the same place, one of granite and the other of marble, they will eventually be of the exact same temperature.However, marble tends to feel cooler to the touch, but that also depends on how polished it is. Basically, something feels cooler if it drains heat from your fingers (or feet) faster than another material. The more a surface is polished, the more contact area it will have with your skin, and the faster the exchange of heat will occur. Also, some materials conduct heat better than others, and this affects the sensation of coolness as well.If you heat up a piece of marble and a piece of granite to the same temperature (higher than your body temperature), polished marble will probably feel warmer than polished granite.Finally, granite and marble are both types of stone :)See Why_do_marble_flooring_feels_cold_to_touchfor another good answer.
What are the similarities between brick and metamorphic rock?
Both igneous and metamorphic rocks are formed by pressure and some kind of heat
Are metamorphic rocks formed by some combination of heat pressure and mechanical activity?
Metamorphic rock can be formed a a combination of heat, pressure, and mechanical activity, or by heat, or by pressure from a mechanical activity such as plate motions.
When heat and pressure is applied to any rock it becomes?
It becomes hot and under pressure. At some stage, with sufficient heat and pressure it could become a metamorphic rock.

Why is granite cool to the touch and wood cabinets are not though they are in the same room at the same temperature and is the granite countertop really cooler?
Granite has a higher specific heat than wood, therefore it takes more energy to raise the temperature of granite than wood. Resting your hand on the counters allows heat from your hand to transfer to each counter top, since wood's specific heat is lower it quickly heats up to equilibrium with your hand, while the granite still require more energy to heat up to the same temperature as your hand, thus it feels cool as heat is transfered from you to the granite.
What are some home uses of granite countertops?
My wife wants to buy some granite countertops. What are some domestic uses for granite countertops?

Do heat and pressure have any effects on rocks?
Depending on the rock type, some may explode from excessive heat and pressure. Others may simply melt, if the temperature is hot enough, like that of magma.
