a.
metamorphism
c.
melting
b.
erosion
d.
petrogenesis
Why is the rock cycle important?
a.
because it describes how water and rocks interact within the Earth to produce melt
b.
because it describes how rocks move throughout the Earth’s ocean basins
c.
because it explains how long rocks have existed on this planet
d.
because it explains how rocks are constantly changing from one type to another
What is the rock cycle?
a.
cycle that rocks goes through when interacting with water
b.
transformation of one mineral type to another
c.
transformation of one rock type to another
d.
cycle that rocks undergo when interacting with air
Which type of rock is formed by precipitation of minerals from a solution?
a.
metamorphic
c.
sedimentary
b.
glassy
d.
igneous
Igneous rocks form from _______________.
a.
heat and pressure applied to a rock
b.
precipitation of minerals out of a solution
c.
sediments cemented together
d.
molten rock cooling and forming crystals
Imagine you are holding a rock composed of small sand grains cemented together. What type of rock is this?
a.
clastic
c.
igneous
b.
chemical
d.
crystalline
a.
metamorphism
c.
melting
b.
erosion
d.
petrogenesis
Explanation / Answer
1) The process of conversion of igneous rock into the sedimentary rock take place due to the process of weathering and erosion. this may be physical weathering as well as chemical weathering to be take place according to the circumtances. metamorphosism is the process of formation of metamorphic rocks and petrogenisis is the formation of igenious rock .
=> so correct option is b) Erosion
-----------------------------------------------------------------------------------------------------
2) Rock cycle is produced to understand the natural process of forming and origination of rock. it is a very important cycle for geologist to undertsant the natural process of rock during it's formation as well as changing from one type of rock to another type.
=> so correct option is d) Because it explain how rock constantly changing from one type to another.
------------------------------------------------------------------------------------------------------
3) Rock cycle can be defined as the conversion of one type of rock to another type by various natural process of conversion like weathering and erosion and then convert in the desire rock when certain like circumtances according to the category of rock is established.
=> so correct option is c) Transformation of one rock type to another.
-------------------------------------------------------------------------------------------------------
4) Sedimentary rock is formed by the settle down of the earth minerals on the surface of the earth crust and hence settle there for a long period of down to form the process of sedimentation. so sedimentation is the rock which formed by the precipitation of mineral from a solution.
=> so correct option is c) Sedimentary.
----------------------------------------------------------------------------------------------------------
5) Igneous rock are formation can be understand by the rock cycle in which it stated that the formation of igneous rock takes place by the cooling down of molten magma on the surface of the earth crust, infact it get converted into the igneous rock from metamorphic rock.
=> so correct option is d) Molten rock cooling and forming crystals.
-------------------------------------------------------------------------------------------
6) It will be a clastic rock. because clastic rock is composed of fragments and clasters of small grains of preexisting minerals and rocks which are cemented together. this process include the physical weathering in it to break the big rocks in to fragments and grain size.
=> so correct option is a) Clastic
