What type of rock is likely to form next when extrusive igneous rock is broken down by weathering?
Sedimentary
Do you think extrusive or intrusive igneous rocks are likely to have larger crystals?
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.
What can you tell about an igneous rock that has coarse-texture?
It is most likely extrusive.
If granite were subjected to intense heat and pressure it would likely change to?
gneiss
What two mineral samples most likely have a similar internal arrangement of atoms?
Intrusive igneous rocks can have chemically and mineralogically identical counterparts in their extrusive igneous equivalent. The only difference between the two rocks would be their method of formation and texture. Example: granite and rhyolite from the same source of magma.
If granite within the earth melts then erupts at the surface what type of extrusive rock is likely form?
A felsic extrusive igneous rock, such as rhyolite or obsidian.
Which rocks are more likely to have a coarse grained extrusive or intrusive?
extrusive
If a lava flow at earths surface had a basaltic composition what rock type would the flow likely be?
A Mafic Extrusive Igneous Rock.
Why could a granite polisher scratch the stones surface?
Most likely it was a loose chunk of granite that popped off, got under the pad and caused the scratch. It happens.
What type of rocks from when magma erupts from undersea volcano?
All three rock types could be formed in areas under the seas. Two types of rock are most likely to form on the seafloor, however. Sedimentary rock is formed on the seafloor where accumulations of sediments undergo lithification processes. Extrusive igneous rock can form on the seafloor when lava erupts on its surface.
Under which conditions will the amount of water in surface runoff be most likely to exceed the amount of water recharging an aquifer?
heavy rain on sloped granite
Will you die if mount st helen erupts?
If you are climbing the mountain and it erupts, yes, most likely you will die. Unless you are bird-man and can fly.
What rock is most likely granite?
afgthh
What rock is most likely to be found in a kitchen?
Granite.
If a lava flow at Earth's surface had a basaltic composition what rock type would the flow likely turn into upon solidification?
It would form into the rock basalt, an extrusive, mafic, igneous rock.
