Explanation:
the rate of weathering is not the same for all rocks. Factors such as surface area, rock composition, and location influence the rate of weathering. water, the faster the rock will break down. A greater surface area allows chemical weathering to affect more of a rock.
Answer:
By providing the numbers in which methane is more powerful than carbon dioxide the author is appealing to the scientific facts to convince people that the greenhouse effect is destroying our planet, and that global warming is a reality that we must counter attack and treat as a priority.

For anyone with this question as a multiple choice question, itś D.
Answer: 0.04metres
Explanation:
The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ
Recall that Velocity (V) = Frequency F x wavelength λ
V = F λ
Make λ the subject formula
λ = V / F
In this case Frequency = 0.4 kHz
Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz
Velocity of wave = 16 m/s
So, λ = V / F
λ = 16 m/s / 400Hz
λ = 0.04metres
Thus, the wavelength of a wave is 0.04metres
