Consider the following statements about igneous rocks
1.Theseprovide information about earth's mantle.
2.Igneous Rocks are the most common type of rock found on earth.
3.Acidic igneous lavais less viscous than basic igneous lava.
How many of the statements given above are correct?
1 and 2 only
"These provide information about the Earth's mantle." - This statement is correct. Igneous rocks, especially those that originate from the mantle, can provide valuable information about the composition and processes occurring in the Earth's mantle.
"Igneous rocks are the most common type of rock found on Earth." - This statement is correct. Igneous rocks are indeed the most common type of rock on Earth, forming from the cooling and solidification of molten magma.
"Acidic igneous lava is less viscous than basic igneous lava." - This statement is incorrect. The viscosity of lava is inversely related to its silica content. Acidic (or felsic) lavas, which have higher silica content, are more viscous than basic (or mafic) lavas, which have lower silica content.
