Why would basalt and gabbro generally have higher chemical weathering rates than rhyolite and granite?
Basalt and gabbro have higher chemical weathering rates than rhyolite and granite because they contain more ferromagnesian minerals like olivine and pyroxene that are more susceptible to chemical weathering compared to the quartz-rich minerals in rhyolite and granite. This makes basalt and gabbro more prone to breakdown and alteration when exposed to weathering agents like water and acids.
Why does granite weather more slowly than rhyolite?
Because granite is harder; it is composed mostly of manganese and iron, it forms first in a lava flow, and it generally deeper underground. Rhyolite has a different chemical makeup; it has a significantly high silica content, making the rock lighter and more prone to the affects of mechanical weathering.
Which is an igenous rock limestone rhyolite slate or shale?
Rhyolite is an igneous rock. Limestone, slate, and shale are sedimentary rocks.
What is a component of granite that is not susceptible to chemical weathering?
Quartz is a component of granite that is not susceptible to chemical weathering. Quartz is a very durable mineral that can resist the chemical breakdown caused by exposure to elements like water and air.
What has a more felsic composition rhyolite or basalt?
Rhyolite has a more felsic composition than basalt.
What is an example of rock undergoing mechanical weathering?
Rhyolite.

Why does Quartz resist chemical weathering more than other common material?
because of its hardness
What is it called when sediment becomes rock?
The weathering, erosion, and deposition of the rock rhyolite could result in the compaction and cementation into sedimentary rock of different types: breccia, conglomerate, sandstone, mudstone, or shale. Which type depends on the degree of weathering and the distance from the point of origin of the original rhyolite.
Is rhyolite a compound?
No. Rhyolite is a mixture.
Is rhyolite igneous?
yes, rhyolite is igneous
Does rhyolite or basalt have more silica in it?
rhyolite
Is rhyolite monomineralic or polymineralic?
polymineralic igneous rock!
How old is rhyolite rock?
Rhyolite can be any age.
Are granite and rhyolite similar in a way?
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
Is rhyolite a metamorphic rock?
No. Rhyolite is an extrusive igneous rock.
