what are the types of Igneous Rocks
Intrusive Igneous Rocks,Extrusive Igneous Rocks
where are igneous rocks found
Igneous rocks can be found in many geological settings, including shields, volcano,platforms, basins, and oceanic crust. They can also be found on the surface of the Earth and beneath the sea floor
Why are igneous rocks often found near volcanoes
because they are formed when magma cools and solidifies above or near the Earth's surface
How are igneous rocks created
Any thing with the term Magma Formation ,Magma Rising ,Cooling and Solidifying:
Which type of rock forms from cooled lava or magma?
A is the answer
What is the difference between igneous and sedimentary rocks
Igneous and sedimentary rocks differ in their origins, compositions, and textures
how are the igneous rocks found
in either large bodies (plutons or batholiths) or are thin sheets that either cut across (dikes) or are parallel (sills) to layering in the surrounding rocks
Why do some rocks contain fossils
because they form at temperatures and pressures that don't destroy fossil remains
How are sedimentary rocks formed
when deposits of organic or mineral particles accumulate on Earth's surface and then undergo compaction and cementation
Which type of rock is created by the transformation of existing rock types through heat and pressure?
C is the answer
what is sedimentery rock made of
deposits of pre-existing rocks or pieces of once-living organisms that accumulate on the Earth's surface
where are sedimentry rocks found
at the bottom or edges of bodies of water, such as lakes, rivers, and oceans
Why do some rocks have crystals, while others do not?
The rate at which magma cools is the main factor that determines whether a rock will have crystals and their size
How do plate tectonics affect rock formation
Folding, faulting, and extension
How is metamorphic rock created
when sedimentary and igneous rocks change in composition and/or texture due to intense heat and pressure from seismic activity in the Earth's crust
What type of rock is most commonly found on Earth's surface
Sedimentary rock
where was the first igneous rock found
Slave craton in Northwest Territories, Canada
Why do sedimentary rocks typically form in layers?
Why do sedimentary rocks typically form in layers?
How do scientists determine the age of rocks
radiometric dating
What are the three main types of rocks?
A is the answer
What causes the formation of sedimentary rock layers
when mineral or organic particles accumulate on Earth's surface and become compacted and cemented together
where was the first rock used
Ethiopia's Lower Awash Valley
Why is granite considered an intrusive igneous rock
it crystallizes from magma that cools slowly deep below the Earth's surface
How are fossils preserved in sedimentary rocks
through a process called permineralization
Kimberlite pipes are formed by volcanic eruptions that carry diamonds from the Earth's mantle to the surface
