Hot magma pushes itself to the surface at both divergent plate boundaries and convergent plate boundaries. This magma comes in contact with rocks as it rises to the surface. The magma is hot, heating the rocks around it. As the rocks heat, they change and become metamorphic rocks.
Answer:
Explanation:
Banded iron formation ( BIF ) -
It is aslo called the banded inronstone formations , are the part of the distinctive units in the sedimentary rocks , which are always of the precambrian age .
volcanogenic massive sulfides ( VMS )-
A type of metal sulfide ore deposit , which have copper - zinc as the main elements , they are formed by in the submarine environments by the volcanic - associated hydrothermal events .
The types of VMS -
Mafic associated - The type of deposits associated with geological environments by mafic rocks.
Bimodal-mafic - The type deposits associated with environments dominated by mafic volcanic rocks.
Mafic-siliciclastic - The type deposits associated with sub - equal proportions of the siliciclastic and the mafia rocks .
Felsic-siliciclastic - The type deposits associated with less than 10 % mafic rock and rest siliciclastic sedimentary rock .
Bimodal-felsic The type deposits associated with more of felsic rocks than mafic rocks.
<u>Stromatolites are layered mounds of calcium carbonate that were deposited by algae during the Precambrian time.</u>
Answer: Option C
<u>Explanation:</u>
Stromatolites are the deposit of the layer which is mostly of limestone and these are mainly formed by the blue green algae which are only one celled organism of primitive times.
The features of these are that they are normally thin and have layers that might be either light or dark in color and are either flat or some of them even have a shape of a dome.
Answer:
The correlation is where the fault lines are and earthquakes have happened, the hazard level would increase.
Explanation:
If you look at California, the earthquake hazard is higher than Florida because of the major fault lines in California. A main fault is the San Andreas fault that has caused major earthquakes, like the one in 1906 in San Francisco.
