All the options are correct.
If we look at the formula of prismoidal, we can see that it contains, three areas = area of faces at top and bottom and area of midway section
Thus it can be used to calculate the a) calculate surface area for cylindrical rings And b) estimate the surface area of edged non-prismoidal solids.
In the volume formula of prismoidal, the factor (depth/6) is multiplied by the three areas as mentioned above, this gives the volume of faces at top and bottom and midway section. Thus option C and D are also correct.
The African continent isn't suffering from the environmental challenge "reforestation", since most of the continent hasn't suffered deforestation.
Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
And Ozone gas is produced .
Answer:
Oceanic water have latent heat or special heat capacity.
Explanation:
- As oceans cover nearly 71% of the earth's surface and help in regulating the climate and weather patterns around places. They have specific heat and contain salt contents.
- They trap and absorb the carbon dioxide and thus are called carbon sinks. They take up a large amount of solar energy and heat slowly as compared to the land surfaces.
