Which types of rocks are formed above ground?
Extrusive igneous rocks are one type of rocks that can be formed above the ground. Sedimentary rocks can also be formed above the ground.
What rocks are formed by the effect of heat and pressure on other rocks?
the metamorphic rocks are formed by heat and extreme pressure from other rocks
Is sedimentary rocks formed the same way normal rocks are?
No, because a sedimentary rock is formed from pieces of other rocks.
What kind of rock is formed when loose rocks and dirt are transported and re-deposited?
sedimentary rocks are formed
Why vesicular texture is associated with peridotites?
Peridotites are invasive rocks formed underneath the earth's surface and the high pressure conditions Dodge gases from forming and getting away
What could a geologist learn by finding rocks that have ripples or mud cracks?
676 ripples means good luck
What causes waves in the rock layers?
depending on the rock. sedimentary rocks are formed under water and may have water wave ripples. metamorphic rock has been pressed into waves. igneous rocks flowed in waves
Where did natural gas start?
Natural gas (and oil) is formed from the fossilized organic remains of sea creatures that were trapped in rocks at the bottom of the sea as sediments accumulated.
What is the name of Dinosaur tracks in rocks?
Fossilized impressions
How do ripples form in sedimentary rocks?
The ripples do not form in the rocks, they form in soft, sandy sediment usually in water. The sediments are preserved after they have been buried, de-watered and turned into rock.
Are clam shells sedimentary rocks?
Clam shells are sedimentary rocks but not until they are fossilized.
What happenes during each method to form intrusive igneous rocks?
Igneous rocks are formed under high heat conditions. Intrusive igneous rocks are formed by the crystallization of magma in the Earth's crust.
Where and under what conditions are metomorphic rocks formed?
They can be formed just about anywhere but are commonly found near the sites of volcanos or places volcanos were once active. They are formed by other rocks put under heat and pressure.
What rock is formed when existing rock is altered by conditions of extreme pressure and temperature?
Metamorphic Rocks
What sedimentary gives info about past conditions of?
Sedimentary rocks are laid down one layer at a time. The layers give information on how the rocks formed.
Do igneous rocks have smaller crystals than those formed above the surface?
Igneous rocks formed within the earth crust have larger crystals than those formed on the surface because they have little or no interaction with atmospheric conditions and they cool very slowly.
What is the difference between facies in sedimentary rocks and facies in metamorphic rocks?
Most regional metamorphic rocks are formed in conditions within this range of geothermal gradients, passing through the greenschist facies to the amphibolites
