Answer:
Scientists have long known that rocks naturally absorb carbon dioxide over thousands of years by binding it with minerals to form solids like calcium carbonate, a common substance found in rocks and the main component of snail shells and eggshells.
Explanation:
Plants use photosynthesis to turn sunlight into energy (they use as food)
Answer:
It is given that a particle covers 10m in first 5s and 10m in next 3s. so using the equation of motion
Case I
s=ut+

10=5u+

a(5)
2
20=10u+25a
4=2u+5a..............(1)
Case 2
In next 3s the particle covers more 10m distance. So
20=8u+
2
1
a(8)
2
5=2u+8a.........(2)
On solving equation (1) and (2)
4=2u+5a
5=2u+8a
a=
3
1
m/s
2
Put the value of a in equation (1)
u=
6
7
m/s
Now to find distance in next 10 s. total time will be 10s
s=

s=28.33m
Distance travelled in next 2 sec
s=28.33−20=8.33m
C. stratosphere is your answer
Most weather balloons are located in the stratosphere to be able to get extremely accurate and stable results. The ozone layer is also located in this area and helps absorb the sun's harmful UV rays before the light reaches us.
