Water cycle
1. true or false:
the earth always has the same amount of water because it
is constantly forming more water and losing water at
similar rates.

True.

Explanation:

Humans are using the Earth's supply of water as the Earth is forming more at the same time.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
