What are some examples of igneous rocks with the meaning?
Igneous rocks are formed from cooling lava. Some examples are obsidian And basalt.
Why do rocks have different colors?
Rocks have different colors because some rocks contain different minerals. the rocks
Do all rocks weather the same way?
Erosion rates depend on the composition of the rocks and how they are attacked by the environment.Different kinds of rocks have different composition and will erode at different rates.Rocks in different places will be affected differently by wind, water, ice, rain, pollutants, etc. and so they will erode at different rates.
What different rocks are there?
There are 3 main types of rocks:Igneous RocksForms when molten rock cools.2 types of molten rock: magma, and lava.Intrusion: Forms when magma cools. Intrusion rocks take longer to form because magma takes longer to cool. Magma is under the Earth's surface, and it is very hot there. Imagine how long it would take for magma to cool down somewhere a thousand degrees!Extrusion: Forms when lava cools. Extrusion don't take as long to form, because lava cools much faster than magma does. Lava is at the surface, and the surface is WAY cooler than underground.Sedimentary RockForms when rocks/minerals/remains of plants or animals settle and accumulate.Forms in layers.3 types of sedimentary rock:Clastic - forms from accumulation of rock fragments and minerals.Biologic - forms from plant or animal remains.Chemical - forms when minerals precipitate out of a solution.MetamorphicPreexisting rocks that have changed form by heat and pressure.If you are looking for specific types, here are some brief examples:Igneous RocksBasaltPegmatiteGraniteTuffSedimentary RocksLimestoneCoalShaleSiltstoneMetamorphic RocksSlateGneissSchistMarble
What types of rocks are formed above ground?
Extrusive igneous rocks and some sedimentary rocks are formed above ground.
What types of rocks are usually present in areas with a lot of caves?
Most caves are in limestone or dolomite rocks. Some (e.g. Carlsbad Caverns) are in gypsum rocks. But caves can also exist in lava deposits (e.g. lava tube caves), marble rocks (i.e. metamorphosed limestone), and many other types of rocks at lower rates, depending on various variables.
What rock would most likely be found near a volcano?
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian , and volcanic ash and dust
Heat and pressure can cause some rocks to change into different types of rocks?
sedimentary rocks
Too many lava rocks on the rack of barbeque?
Take some of the lava rocks off. Too many is just as bad as too few.
What are some of Hades' favorites?
lava rocks and human eyes
What type of rocks form due to cooling?
The earth is composed of various types of rocks, some formed as a result of pressure while others due to cooling. Igneous rocks form when molten lava cools and solidify to form crystals.
What are some examples of igneous rocks with the meaning?
Igneous rocks are formed from cooling lava. Some examples are obsidian And basalt.
Why are there different types of volcano?
there are different types of volcanoes for different reasons. how they form has alot to do with the type of lava said volcano produces. fluid basaltic lava tends to create shield volcanoes. spatter cones tend to form when hot erupting lava contains just enough explosive gas to prevent the formation of a lava flow, but not enough to shatter it into small fragments. hot expanding gas tears the lava into hot fluid clots.
Can magma melt iron?
Yes, magma can melt iron. Since magma is already extremely hot, and since it is hotter than iron's melting point, magma can melt iron.
