Hard to answer when there is no map.
<span>i think the correct match would be :
B. neotropc south America
if we look at it physically, the Neotropic ecozone includes the tropical terresterial ecoregions of the Americas continent and it also cover the entire Temperate zones of south America.</span>
The volume of the cone is calculated by the formula:
V = B*H/3
r=D/2 = 6/3 = 2
where B is surface area of basis and H is height.
B is circle which fomula for surface is:
B = r^2 * pi = 3^2*3,14 = 9*3,14 = 28.26
from condition of height we write:
H = 3*D = 3*6 = 18
now volume is:
If we express all of that in equation of volume we get:
V = 1/3* 3^2*3,14*18
Answer:
C. acid drainage
Explanation:
Many types of mining, such as for coal and copper, produce a specific type of water pollution called ___<u>acid drainage</u>_____.
1. Weathering is the breaking down of rocks, soil, and minerals.
Erosion is the process of eroding or being eroded by wind, water, or other natural agents.
2. <span>First the rocks on the surface of the earth are weathered, this causes erosion, so then they are eroded. Finally they are deposited. This deposition can lead to the formation of sedimentary rocks.</span>
