What has a very high mineral?
Rocks, water, ore etc
Do certain rocks float on water?
Pumice, a volcanic rock that is like a silicate version of Styrofoam, will float on water, if it is of high enough air content (some pumice is, some is not). Pumice rock is ground up and added to cleansers and some soaps (Lava) as a scrubbing agent.
What has a very high mineral content?
Rocks, water, ore etc
Would you expect extrusive rocks produced by an explosion volcano to be light or dark in color?
The color of igneous rocks is tied to their composition. Rocks (minerals) that have a high concentration of Fe, Mg and Ca, tend to be darker colored than those that are rich in Al, Si, and K. So, the volcanic rocks like rhyolite are light in color due to their composition. However, there are many volcanic rocks, like andesites, that are a bit darker, and those form from explosive volcanoes like the Cascade volcanoes of western North America.
Is rhyolite a basaltic composition?
No. Basalt is a low-silica igneous rock while rhyolite is high-silica. As far as volcanic rocks go, they are essentially opposites.
What does the rate of cooling determine about igneous rocks?
The rate at which a rock cools will determine its grain or crystal size. Igneous rocks are widely classified into volcanic, hypabyssal and plutonic. Those that cool deep inside the earth are plutonic and those that cool and crystallize at or much near the Earth's surface are volcanic. The intermediate rocks are the hypabyssal ones. Volcanic rocks come immediately in contact with air or water and get quenched developing finer grained crystals that are best identified under a petrological microscope or a high power electron microscope. But plutonic rocks have a hell lot of time to cool due to their hotter surroundings resulting in well grown big crystals, which can usually be identified by naked eye or with the help of a hand lens. You should have now guessed the hypabyssal rocks will have medium sized crystals.
How many types different material throw by volcanoes?
There are lots of material that is being throwen by vocanoes--such volcanic tuffs,volcanic ash these are all classified dependind upon their size.As we all know volcanoes are eruption of molten magma under very high pressure nad temperature. Molten magma is nothing but the dissolved rocks or rocks in liquid form which gets melted under high temperature and pressure deep inside the earth.
What materials make up a shield volcano?
They are made of rocks and also hardened layer of ash and lava that have piled on top of each other.
What type of rock is lamporite?
From Wikipedia: Lamproites are ultrapotassic mantle-derived volcanic and subvolcanic rocks. They have low CaO, Al2O3, Na2O, high K2O/Al2O3, a relatively high MgO content and extreme enrichment in incompatible elements.
How high ash goes from a volcanic eruption?
to high for me to jump
Is it true that a hot spring is hot water and steam that erupts from the ground?
Yes, that is correct. A hot spring is a natural occurrence where groundwater is heated by geothermal activity, usually volcanic, and emerges at the Earth's surface. The heat can cause the water to reach high temperatures and create steam.
What is composition of acidic igneous rocks?
Acidic igneous rocks, also known as felsic rocks, are composed primarily of light-colored minerals such as quartz, feldspar, and mica. These rocks have a high silica content and typically have a lower iron and magnesium content compared to mafic rocks. Examples of acidic igneous rocks include granite and rhyolite.
