How is phyllite formed?
Phyllite is a fine grained metamorphic rock. It is formed by shale forming into slate, and slate being put under physical pressure over time.
True or false granite is a fine grained igneous rock?
False. Granite is an intrusive igneous rock and so commonly cools slowly so has time to develop moderate to large crystals.
Which type of rock is formed when loose grains of other rock are consolidated by time and pressure?
Sedimentary rock, though that category also includes rocks formed when a cementing material precipitates out of groundwater between the grains.
3 types of rock and soil?
The three types of rock are:Igneous rock- these are formed from the cooling and solidification of magma/lava below or at the surface of the earth. e.x. GraniteSedimentary rock- These are formed from the accumulation of sediments, broken off from other rocks, that are being cemented together over a long period of time. They are usually formed under water. e.x LimestoneMetamorphic rock- These are rocks that have been changed overtime, due to heat and or pressure. They were once either Igneous or Sedimentary. e.x. Limestone - MarbleGranite - GneissThree types of Soil are:ClaySandSilt
How can a metamorphic rock become an extrusive igneous rock?
a metamorphic rock is formed when it is under great heat and pressure and after some time it forms magma. then the mama comes out through volcano and becomes hard , this rock that is formed is known as extrusive igneous rocks.
How is phyllite formed?
Phyllite is a fine grained metamorphic rock. It is formed by shale forming into slate, and slate being put under physical pressure over time.
Sedimentary rock becomes metamorphic rock after millions of years True or False?
It must be false, because the statement in question is not valid all the time. Sedimentary rock might become metamorphic rock after millions of years, but it might take less time, more time, or not happen at all.
What does the magnetic dip preserved in a rock indicate?
the rock's magnetic latitude at the time that it formed
How was table rock formed?
By lakes a long time ago
What rock formed out of sediment that have been pressed or cemented over a long period of time?
sedimentary rock
How does cooling time affect the type of rock formed?
Makes it hard .(:
Where do sedimentary rocks most form?
They have been formed throughout geological time since the Earth had cooled sufficiently to form a solid crust, and for its load of water to condense and form rivers and seas. It's a continuing process. For all the older rock being eroded in one place, new sedimentary rock is being formed elsewhere.
How would you define sediment and sedimentary rock?
Sediment is small particles of rock, minerals, or organic material that are deposited on the Earth's surface by wind, water, or ice. Sedimentary rock is a type of rock formed by the accumulation and consolidation of sediments through processes like compaction and cementation over time.
What does quick cooling of ejected lava result in?
Quick cooling of ejected lava results in the formation of glassy volcanic rocks, such as obsidian or pumice. These rocks are formed when the lava solidifies so rapidly that crystals do not have time to form within the rock. The resulting texture is usually smooth and non-crystalline.
True or false granite is a fine grained igneous rock?
False. Granite is an intrusive igneous rock and so commonly cools slowly so has time to develop moderate to large crystals.
Which type of rock is formed when loose grains of other rock are consolidated by time and pressure?
Sedimentary rock, though that category also includes rocks formed when a cementing material precipitates out of groundwater between the grains.
What do the size shape and position of the grains that make up a rock determine?
If the grains of the rock are larger, then it either is an intrusive igneous rock,( a rock formed from molten rock that cooled slowly over long periods of time underground) or a sedimentary rock that was formed from large sediments.
