PLEASE HELP!!! ASAP

Imagine you placed a limestone with a surface area of 1,000 cm2 in a lush, tropical
environment. You also put a quartzite rock with a surface area of 100 cm2 in desert
climate at a high altitude that experiences various cycles of freezing and thawing
throughout the year. Which rock do you think would weather at the fastest rate?
Why?

the one with the the limestone thingy is faster because the friction is loss

Answer:

Limestone will be weathered faster than Quartzite

Step-by-step explanation:

Limestone is a sedimentary rock that is formed from the collection of organic elements such as shells of organisms, along with other sediments. They are made up of calcium carbonate and these sediments are compacted and solidified and forms limestone over a specific period of time.

On the other hand, Quartzite is a metamorphic rock that forms when quartz rich sandstone undergoes metamorphism. They contain abundant quartz, which is a hard and resistant mineral.

Limestone is weathered at a much faster rate than Quartzite.

Limestone breaks down by chemical weathering process when rain water containing carbonic acid precipitates and falls over the surface of the rock. Whereas, quartzite is comprised of quartz that is comparatively dense, hard and resistant. So, they are affected at a much slower rate.
