100% for Connexus in Grade 7
Credit to schoolboy 1. oxygen
2. carbonation
3. water reacting chemically with the minerals in the rock
4. a tropical region that is hot and humid all year round dd was right 100 for connexus idk who to believe. Don't listen to that moron, moron. jj was right for me jj is 100% right thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you thank you JJ!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! 100% for JJ ru sure kk?

Yes jj is right even in 2021 do not follow the letters but you will be wrong! 1. Oxygen 2. Carbonation 3. Water reacting chemically with minerals in the rock 4. A hot and humid tropical region all year round. THIS IS FOR CONEXIS!!! thx @jj 100% correct, your learning coach has the answers on his page, just tell him to check your work and tell him to go see your quick check on his page and you can get the answers for science and reading! jj is right for connexus just use the words not the letters jj said answers for grade 6 who is right jj was right for me i got 4/4=100 jj is right!!!!!!! !! JJ and the person from school have the same answers for your information helppppppp. thank you @JJ is 100% correct for the year 2021 and the 6th year Connexus dbcd 1. d
2.b
3.c
4.d why yall cap so muchh jj right jj probably changed his name and said all those things pretending to be other people Thanks to school boy ;w; The answers are 1.An oxygen
2. Carbonation
3.D Water chemically reacting with the minerals in the rock
4.C a hot and humid tropical region all year round JJ IS RIGHT!!! DON'T HATE HIM BC UA USED THE NUMBERS HE GAVE!!!!!!!!!!! Oops...sorry for all the capitalization...ok, I just saw a 7th grade answer and some other answers, so be sure to tell us what grade it is. TT also i got 100% from jj so7th graders maybe you might want to look for other answers - ok so this is for login students and here is the answer to the chemical weathering quick check
What substance combines with iron in the presence of water to form rust?
nitrogen
(oxygen = response)
acid
carbon dioxide
What process is most likely responsible for the formation of limestone caves?
oxidation
abrasion
(carbonation=response)
hydrolysis
Which option best describes hydrolysis?
carbon dioxide reacting with water to form an acid that dissolves minerals in rock
hydrogen in water combining chemically with substances in rock
oxygen in the water combining chemically with substances in the rock
(water reacting chemically with the minerals in the rock = answer)
What type of region would be most likely to support chemical weathering?
a cold and dry polar region all year round
a desert region with very little rain
a temperate region with hot summers and cold winters
(a hot and humid tropical region all year round=answer)
hope it works 🙂 I will give the answers when I finish this test JJ is right
100% Yaas no one is wrong 1.oxygen
2. carbonation
3. water reacting chemically with the minerals in the rock
4.a hot and humid tropical region all year round
I promise it's true I got 100% Thx JJ what's the dam's answer what's the dam's answer JJ is right I just passed the 6 A science test and got a 100 Oxygen
carbonation
Chemicals reacting in water with minerals in rock
A hot and humid tropical region all year round
Trust me for the 2021 chemical connexus rapid weather control

believe me this is 100% correct they are wrong as of 2021 DONT K+LISTEN TO JJ dd is just for connexus 6th grade ONLY not for connexus 7th grade JJ is 100% correct just use the words not the letters. JJ IS WRONG I GOT 0/4 JJ is right I got 100 don't listen to them for science Grade 6 connexus For grade 6 conexus no lie is true. Or JJ is right. guys @ boo bies is correct all answers are the same as jj so you can trust him .............................. .. ................................ also jj is not a model Attention students!

2. The most likely answer is carbonation although hydrolysis plays a role. I suggest you google limestone cave formation and read about it.
3. There are two correct answers (b and d). Hydrolysis is the reaction with water to..... Again, google to see which works best or look at your notes.
4. The best answer is b. got 2/4 the real answers are
1.B
2.A
3.C
4.C dd is wrong dd is wrong
