The number that Colorado River would have to downcut per year to form the mile-deep canyon in 4 million years is 0.40 millimeter per year.
Depth of canyon = 1 mile
Time taken = 4 million years
Based on the above information, the rate will be:
= Depth / Time taken
= 1 mile / 4 million years
= 0.25 mile / million year
Note tha<em>t 1 mile = 1609344 millimeter</em>
<em />
Therefore, the rate will be:
= (0.25 × 1609344) / 1000000 years
= 0.40 millimeter / years
In conclusion, the rate is 0.40 millimeter per year.

Elastic deformation: the rock returns to its original shape when the stress is removed. plastic deformation: the rock does not return to its original shape when the stress is removed. fracture: the rock breaks.
Answer:
Venus - has the most circular orbit .
Explanation:
Eccentricity -
Eccentricity is used to define the circularity of an object .
Lesser the value of eccentricity of the orbit , more circular will be its orbit
and ,
More the value of eccentricity of the orbit , less circular will be its orbit .
In case , the value of eccentricity is zero , the orbit will be a perfect circle.
Hence ,
by considering the eccentricity value of the following plants as -
Venus 0.007
Earth 0.017
Mercury 0.206
Pluto 0.248
Venus has the most circular orbit , as it has the minimum eccentricity value , i.e. , 0.007.
