It's all about Weathering

This week in our Natural Science subject, we were tasked to bring kinds of minerals or stone in class, but I didn’t have the opportunity to bring any of those. Where the heck am I going to find those kinds of stuffs in the heart of manila? Anyway, the fact that I don’t have an assignment, makes me feel so nervous while waiting for our professor, I was hoping that he’ll forget the homework, A few minutes later; I was shocked when one of the BEST students in class reminded him about the assignment.  I was really in delight of what she did and wanted to kiss her on the cheeks!  Who wouldn’t be so happy??    Of course, some of our diligent classmates won’t gain any grade if it wasn’t for her, RIGHT?!! After that electrifying “mini recitation” that we had about stones, our class proceeds to reporting. Here’s one of my favorite report discussed: It is about Weathering.

Weathering, is a process that changes the Earth's surface. Weathering is the breaking down of the solid part of the Earth's solid surface. Rocks are broken down into smaller and smaller pieces until they become part of the soil. Many things can cause this breaking down: wind, water, ice, plants, animals, and chemical changes. Weathering is a slow process. It is also a continuous process.

There are two types of Weathering:


Mechanical weathering only changes the size of the rock. The rock's chemicals are not changed, and no new substances are created. 



Heaved


River rocks


Chemical weathering is different. It changes the chemical makeup
of the rock. New substances are created. For example, rocks with iron in them may rust. Oxygen and iron combine to create a new substance (rust). The rocks may have a rusty-red color on the
outside, but when broken, are dark on the inside.



 Decomposes or decay rocks


Dissolution

That's all folks. :))
