Rock Cycle basics
What is the difference between magma and lava?
Magma is a really hot semi-liquid rock under the earth's surface. The Earth's surface consists of the Crust, Inner core, outer core, and mantle. Magma mostly consists of the mantle and lava. But Lava is another type of material.
What is the definition of Igneous Rock?
An Igneous Rock is when lava cools down and turns into a rock.
What is erosion?
Erosion moves rocks away from its original place by wind, water, or ice.
What are the three types of rock
Metamorphic, igneous and sedimentary
What are all of the rock processes?
The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.
What is the definition of Sedimentary rock?
Sedimentary rocks are types of rock that are formed by the deposition of mineral or organic particles at Earth's surface.
What is weathering?
Weathering is warning down the rock and smoothing it by making contact with the atmosphere.
Which rocks can float in water?
Pumice stones are the rocks which can float on water. While scientists have known that pumice can float because of gases in its pores(holes). It was not known how those gases stayed trapped inside the pumice for very long periods.
What type of rocks have the most crystals?
The type of igneous rock that usually contains large crystals is an intrusive igneous rock.
What is the definition of Metamorphic rock?
Metamorphic rocks are rocks that have been changed from their original form by a lot of heat or pressure.
What is Lithification
Lithification is when clay, sand, and other sediments at the bottom of the ocean are being compressed by the body around it and sediments fall and compress it.
What is the hardest type of rock?
Metamorphic rocks are almost always harder than any other rock because they have gone through many processes. They are usually as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are worn off.
What are the types of sedimentary rocks?
There are three different types of sedimentary rocks, these include clastic, organic, and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.
What are sediments?
Sediments are loose pieces of minerals and rocks.
What is compaction?
Compaction is a process that turns sediments into sedimentary rocks
How are rocks and minerals used at homes?
Rocks and minerals help us to develop new technologies that are used in our everyday lives. Our use of rocks and minerals includes building materials, batteries, cars, roads, and appliances. In order to maintain a healthy lifestyle and strengthen the body, humans need to consume minerals daily.
What types of rocks are formed by volcanoes in the rock cycles?
Igneous rocks are formed inside of the earth, they are called intrusive, or plutonic, igneous rocks. If they are formed outside or on top of Earth's crust, they are called extrusive, or volcanic, igneous rocks.
What is the difference between Intrusive Rocks and Extrusive Rocks
Intrusive Rocks are rocks that form inside the core of the earth and Extrusive Rocks are from on the surface of the Earth.
What is heat and pressure?
Heat and pressure is when the rock turns into a metamorphic rock.
How are diamonds made?
Diamonds form when carbon goes deep within the earth(approximately 90 to 125 miles below the surface) and are faced with high temperature and lots of pressure. Some stones take shape in a matter of days or months, while others take millions of years to form.
