Which are examples of chemical weathering? Choose the two correct answers.
an increase in temperature in daytime causing a rock to crack
an insect digging a hole in rock for its home
rock breaking apart during a rock slide
oxidation of certain metals in rock***
acid rain breaking down compounds in rock statues***
I agree with your answers
I hope it was right
Well, well, well, it seems we have a question about chemical weathering! Let's see which two examples make the cut.
First off, we have "an increase in temperature in daytime causing a rock to crack." Now, this sneaky trickster may seem like chemical weathering, but it's actually a case of good ol' physical weathering. Sorry, but it didn't make the cut.
Next up, we have "an insect digging a hole in rock for its home." Oh dear, that's not chemical weathering either. That's actually biological weathering caused by those industrious little critters.
Moving on, we have "rock breaking apart during a rock slide." Oh, my sides! That's physical weathering once again. Seems like rocks just can't catch a break from all that rock-sliding shenanigans.
Finally, we get to "oxidation of certain metals in rock" and "acid rain breaking down compounds in rock statues." Ding, ding, ding! We have a winner! These two examples are indeed chemical weathering processes. Oxidation and acid rain truly know how to bring the party to rocks and statues!
So, the correct answers are: oxidation of certain metals in rock and acid rain breaking down compounds in rock statues. Keep on laughing and learning, my friend!
The correct answers are:
- Oxidation of certain metals in rock.
- Acid rain breaking down compounds in rock statues.
To determine the correct examples of chemical weathering, we need to understand what chemical weathering is. Chemical weathering refers to the breakdown and alteration of rocks and minerals through chemical processes. The two correct answers among the options are:
1. Oxidation of certain metals in rock: This is an example of chemical weathering that occurs when certain metals in rock react with oxygen in the air. This reaction can lead to the formation of rust or other chemical compounds that weaken the rock.
2. Acid rain breaking down compounds in rock statues: Acid rain, which contains acidic components like sulfur dioxide and nitrogen oxides, can react with rocks and minerals. Over time, this chemical reaction can break down the compounds in the rocks, causing them to deteriorate.
The other options, such as an increase in temperature causing a rock to crack and an insect digging a hole in a rock, are examples of physical weathering and not related to chemical processes. Rock breaking apart during a rock slide is also primarily driven by physical forces rather than chemical reactions.
