Answer:
c) Combustion of fossil fuels
Explanation:
Burning of fossil fuels is the main cause of increasing carbondioxide concentration in the environment which results in air pollution. This increase in carbondioxide concentration absorbed more heat energy from reflected solar radiation which increases the temperature of earth surface causes global warming. Due to this global warming, snow melting occurs on the poles of the earth which increases sea level.
C) Occurs in areas without soil.
Primary succession occurs in lifeless areas in which <span>soil that is incapable of sustaining life is formed due to lava, sand dunes, and </span><span>rocks left from a retreating glacier.</span>
Answer:
The answer is 6.4 × 
Joules
Explanation:
This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:
Force = 8.0 pN = 8.0 × 
N
displacement = 8.0 nm = 8.0 × 
N
Now let us calculate the work.
work = Force × Displacement
work = 8.0 × × 8.0 × = 64 × 
= 6.4 × 
Joules (in standard form)
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
Herpes would be one of them
