No, there are more. There is Oxidation, which is the reaction of rock minerals with oxygen. Carbonation is the process of rock minerals reacting with carbonic acid. Hydrolysis is a chemical reaction caused by water, the water changes the chemical composition and size of minerals in rock, making them less resistant to weathering and Hydration is the absorption of water into the mineral structure.
No, they do the same thing in the end but they use a different process. Chemical weathering uses chemicals to wear away at rocks and mechanical is any type of physical weathering.

No, ancient knowledge and that knowledge is supported by many depictions that we find in museums on statues, cylinder seals, coins etc. The last time that this celestial body, planet X or nine, was seen and depicted and commented was just before our era.

I can't be the only one that had to watch this for school.
Me too
U not
Katsuki Honeyy I did nod I watch bnha
I had to watch it for school too 🤣
Me toooooo whyyyyyy
this man is a life saver he help me understaned my home work
Faquim Awatef same!!
except I knew it, just was reveiwing
BOIIIII YOU SHOULD LEARN THAT YOW SELF
Faquim Awatef Same but he helps me with a test
Faquim Awatef Same but he helps me with a test
This vid so helpful. It helped me understand more about those three because i always get them mixed up, especially erosion and deposition 😄.
It is a very informational video tho ........😶
yay an Australian who does educational videos
I had to watch this and it wasn't a waste
10.4 Notes
Overview:
Weathering
Mechanical weathering
Chemical weathering
Erosion
Deposition
Weathering is caused by the elements wearing away at the surface of a rock
Breaks the rock into smaller rocks or sediments which can be mechanical weathering or chemical weathering
Mechanical weathering is any form of physical weathering - wearing away of rock by wind and water over thousands of years
Water freezing can cause mechanical weathering when the frozen water cracks it expands and acts like a wedge cracking the rock. Tree roots can also act as a wedge causing weathering.
Chemical weathering is the process of chemicals wearing away layers of rock.
Example: acid rain as it dissolves rock such as limestone and marble increasing effect of weathering.
hope this helps!!
here for school. taking online notes lol
My friends : done with homework in 5 mins and now watching videos
Me: sitting here for two hours still not done with H.W and now watching this video 😭
I hope it helped.
It did help a lot tho ......
i know im not the only one watching this for school
Thanks for likening my comment
You're welcome. I hope you got something out of the video. Cheers for watching.
soooo underrated
The roads in Orange seem to break up really quickly. Is that because of mechanical weathering due to temperature extremes?
It is because of vehicles driving on the surface of the road, and also because of poor maintenance.
halo from the UAE
G'day from Australia. Ma salama.
i had to watch this for a project
What other chemicals can fall into the category of chemical weathering or is it only acid rain.
No, there are more. There is Oxidation, which is the reaction of rock minerals with oxygen. Carbonation is the process of rock minerals reacting with carbonic acid. Hydrolysis is a chemical reaction caused by water, the water changes the chemical composition and size of minerals in rock, making them less resistant to weathering and Hydration is the absorption of water into the mineral structure.
@@rosieflatau2300 whoa
Wouldn't chemical weathering still be mechanical weathering because chemical weathering is still doing something physical to the rocks?
No, they do the same thing in the end but they use a different process. Chemical weathering uses chemicals to wear away at rocks and mechanical is any type of physical weathering.
This is good
LETS SEE ELSE IS HEAR FOR ONLINE SCHOOL
How does acid rain form?
Acid rain forms when nitrogen and Sulfur dioxide are released into the air, they rise up in the atmosphere and react with water and oxygen
in a more simplified answer: pollution
How long will it be until the water wears the 12 apostles away and the collapse into the water
The twelve apostles are getting eroded away about 2cm a year. But the stacks are falling all the time, there is currently 8 left
well 6 left now that its 2017
Hi
So why did I have to watch this for school???
i thought your pfp was captain america
Thanks?

Cool theory mate
I LOVE YOUR VIDEOS
JK I DONT
Well done mate. Gold.
thanks ive been practicing
