This science lesson discusses oxidation. Oxidation is a chemical weathering process where oxygen combines with another substance to form compounds called oxides. It occurs when oxygen and water react with iron-rich materials, weakening their structure and causing them to change color and form rust-like stains. Examples are given of how oxidation causes rusting of iron and corrosion of some metals. The key characteristics and disadvantages of oxidation are explained.

2. Welcome!
Doyouknowwhat is oxidation?

o f t h e o x i d a t i o n :
- Oxidation isa another kind of chemical
weathering that occurs whenoxygen combines
with another substance and creates compounds
called oxides.

4. - An oxide is a chemical compound that contains
at least one oxygen atom and one other element
in its chemical formula.
- Oxidation ischaracterized by red, orange, and
yellow stainsthat look like rust.

5. Process of Oxidation:
-Oxidation occurs when oxygen and
water react with iron rich
materials and it weakens
the structure of metal.
-During oxidation the minerals in the
rock will change color, turning into a
'rusty', reddish orange appearance.

7. DISADVANTAGES OF OXIDATION
1
-it causesrusting of Iron and Corrosion of
some metals.
2 -It also causesweakensof metals or iron
materials
