Rocks in continental crust are as old as years.?

Rocks in continental crust can be as old as about 4 billion years. This is because the continental crust is made up of a mixture of ancient rocks that have been around since the Earth's early history. By studying these rocks, scientists can learn more about the planet's evolution and geological processes.


Was Igneous rocks were the first rock type to appear on earth?

Yes, by their constituents being the planet's primary materials. Sedimentary rocks started to form only when erosion of the original land created the sediment. Metasediments came later still, as plate tectonics started to metamorphose the early sediments.


What are facts about malleable rocks?

Malleable rocks are rocks that can be easily shaped or molded without breaking. They tend to be softer and more pliable than harder, more brittle rocks. Examples of malleable rocks include talc and soapstone.


Do dark rocks absorb more heat than light rocks?

Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.


Are Brittle rocks are more likely to fold then fault?

Brittle rocks are more likely to fault than fold because they are more prone to breaking and fracturing under stress. Folding is more common in ductile rocks that can deform and bend without breaking.
