Explanation:
Weathering is the name given to the process by which rocks are broken down to form soils.
Answer:
The greenhouse effect is a natural process that warms the Earth's surface.
Explanation:
When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. Greenhouse gases are absorbed energy that warms the atmosphere and the surface of the Earth.
the equation would be (3w+w)2=32.
this means you add 3 times the width p,us the width (length plus width).
this becomes 6w=32.
w=5 1/3.
l=3w
l=3(5 1/3)
l=16
