Which two types of rock can form on the Earth's surface?
Some types of igneous and sedimentary rocks can form on Earth's surface.
What is the most common mineral found on the surface of the earth?
It is mostly soil and black rock. The Earth is usually made from the steaming lava in its second inner core and mostly metallic copper( Some of it is copper).
Why do some partly molten material rise toward Earth's surface?
Magma is molten or partially molten rock beneath the earth's surface and is lighter than the surrounding rock so it tends to rise. As it moves upward, the magma encounters colder rock and begins to cool.
What is basic Igneous Rock?
Igneous rocks are formed from the solidification of molten rock material. There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below Earth's surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above Earth's surface. Pictures and brief descriptions of some common igneous rock types are shown on this page.
The surface of the earth is made up of?
Well, that depends upon where you are. two-thirds of the Earth's surface is water, some is ice and snow, some desert, some farmed fields, and some is in its natural beautiful condition. The immediate sub-surface of the solid bit will be soil, then clays lower down, then rock.
Why doesn't meteor hit the Earth's surface?
Yes, they do. Just this week (January 18, 2010) a meteor crashed through the roof of a doctor's office in Virginia and landed on the floor of the examining room. Granted, MOST meteors burn up in the atmosphere and don't survive the passage. But some do.
How do volcanopes make igneous rocks?
They extrude to the surface of the Earth and and as they solidify they become harder and form a ignous rock. Some form below and some form above surface. The basalt are the surface one and the Granites are the intrusive ones.
Do igneous rocks that form inside the Earth's crust look different from the igneous rocks that form on the Earth's surface?
Yes. Igneous rock that forms on the surface will have small mineral crystals, or in some cases no mineral crystals. Igneous rock that forms below the surface will have larger mineral crystals, from the additional cooling time afforded by the insulating effects of the surrounding Earth material.
Wh at is magma?
a mixture of molten or semi-molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets and some natural satellites.
What can heat and pressure deep beneath Earth's surface change any rock into?
Some form of metamorphic rock would result; if the temperatures are high enough, the rock could partially or completely melt, resulting in magma.
What does groundwater mean in the water cycle?
Large Underground deposits of water underneath the earth's surface.
What percentage of earth's interior is composed of igneous and metamorphic rock?
The "earth's interior" is thought to be composed of magma and, at the core, molten iron and perhaps some nickel. If we look out on the crust of the earth, some 75-80% of the surface of our planet is composed of sedimentary rock. That leaves some 20-25% left to be composed of igneous and metamorphic rock.
