The surface area of a sphere can be approximated as follows:
surface area = 41772;
where ris the radius of the sphere;
tt is a constant that is roughly equal to 3.
using the simple approximation above, calculate the surface area of a sphere
with a radius of 7 meters.
a. 1,372 m2
b. 14 m2
1000
c. 588 m2
d. 84 m2

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

the answer would be..

b. sucking

a covalent bond, specfically triple bond

the answer would be   10%
