Overtime, weather can shape our land in ways such as water levels rising or ice melting. Heat that is in the earth's molten core can over time cause lands to move (ex. Continental drift) and much more. Water levels are a problem mainly because of the rapid human population growth rate. In the future, weather could change the way that we live our lives.
With
we have
so 
has one eigenvalue, 
, with multiplicity 3.
In order for to not be defective, we need the dimension of the eigenspace to match the multiplicity of the repeated eigenvalue 2. But 
has nullspace of dimension 2, since
That is, we can only obtain 2 eigenvectors,
and there is no other. We needed 3 in order to complete the basis of eigenvectors.
