Sedimentary
How do crystalline sedimentary rocks form?
Crystalline sedimentary rocks form from chemical reactions in which minerals within water form crystals and precipitate out of the solution.
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz,
Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies.
What powers Earth's rock cycle?
Earth's internal heat engine
How does a volcano form
Subduction allows water from the subducting plate to be driven upward, off the subducting plate and into the mantle wedge. This lowers the melting point of the mantle, and it melts to form magma. This magma will rise and leak into the crust forming a volcano.
How are sedimentary rocks formed through physical processes?
Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.
Non-foliated metamorphic rocks do not have a platy or sheet-like structure
Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.
What process causes igneous rock to transform into metamorphic rock?
high heat, high pressure, hot mineral-rich fluids
what is magma
Magma is extremely hot liquid and semi-liquid rock located under Earth's surface. When magma flows onto Earth's surface, it is called lava.
How are sedimentary rocks formed through chemical processes?
Chemical sedimentary rocks form by chemical precipitation that begins when water traveling through rock dissolves some of the minerals.
Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies.
What rock groups can form from metamorphic rock?
The rock groups that can form from metamorphic rocks are sedimentary and igneou
they can spew hot, dangerous gases, ash, lava and rock that can cause disastrous loss of life and property, especially in heavily populated areas.
Why must water evaporate for sedimentary rock to form?
Water must evaporate for chemical sedimentary rock to form because the evaporation process removes the water from the mineral solution, allowing the minerals to form rock.
when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
About 75% of the Earth's crust is made up of igneous rocks.
When do rocks change form in the rock cycle?
if it is exposed to extreme heat and pressure within the crust.
An increase in the frequency and intensity of felt earthquakes.
Whats a fact about rock
There are three main types of rocks: sedimentary, igneous, and metamorphic.
The central cores of major mountain ranges consist of intrusive igneous rocks
What is a rock
a rock is a rock
If outside at the time of eruption, seek shelter in a car or a building. If caught in volcanic ashfalls, wear a dust mask or use a handkerchief or cloth over your nose and mouth.
