What does magma that is blasted into the air form when it hardens?
Extrusive igneous rock.
Some metamorphic rocks are potential environmental hazards because?
Foliation weakens the rock- landslides are possible, rock can break off and crush your car after falling 300 feet through open air, yada ya
What change does fe203 form on a Fe iron pipe exposure to humid air illustrate?
mechanical nuclear chemical physical
What role does magma play in the rock cycle?
Volcanoes effect rock formations a lot, since magma is molten rock, when it cools down and sets, it will turn back into rock, usually it will dry and turn black, but sometimes it can turn a dark grey. It will cover up other rocks, and make new rocks.
How did Pasteur solve limiting exposure to air?
he used s neck valves, cutting off exposure to microorganisms, not air
Does exposure to air help metamorphic rocks form?
No metamorphic rocks are formed deep in the crust under great temperature and pressure. No air is down there.
What sequence of events would have to take place to change a metamorphic rock into an igneous rock?
lava dries air smoothens it and water confines it
What is the difference of a metamorphic rock and a sedimentary rock?
The difference of metamorphic rocks from igneous and sedimentary rocks is on the way these rocks are formed. Igneous rocks form when magma cools down and becomes solid while sedimentary rocks form due to erosion and weathering of the Earthâ??s material, whereas, metamorphic rocks are formed as a result of rock transformation called metamorphism.
Can air make up a metamorphic rock?
Rocks are normally composed of interlocking mineral crystals or clasts. It is rare for metamorphic rocks to be porous and as such there is likely to be very little if any air in them. An example of a very porous rock due to the presence of gasses coming out of solution from a lava is pumice.
What is the metamorphic form of pumice?
Pumice is easily broken down because of it contains numerous air pockets. The metamorphic forms of pumice are gneiss, schist and slate.
Why the pH of fresh groundwater slightly decrease upon exposure to air?
oxygen form air is dissolved in water
The ability of solid rock to flow?
the lighter the rock is the easier it is able to flow. there is a rock that is so light it flows through the air like a feather. rock starts out as magma until it cools after erupting from volcanos. but only igneous and metamorphic rocks.
What kind of igneous rock will form when a volcano sends lava into the air?
extrusive igneous rock
How can tell igneous and metamorphic rocks apart?
Igneous rock forms from the cooling of magma. This forms a rock that is uniform in composition, and sometimes contains air pocketed texture from the process of cooling. Sedimentary rock is formed of small bits of dirt and stone that bind together after they settle as sediment. This rock is usually distinguishable by the flecks of different types of rock and dirt. Metamorphic rock is any type of rock that is transformed by heat, pressure, or chemical changes. It often becomes denser and smoother than the rock from which it changed.
