<span>Mexico has two mountain ranges (Sierra Madra Oriental and Sierra Madre Occidental) that run generally north-south along the majority of the mainland (that is, everything other than the Baja Peninsula). If you look at an east-to-west cross section of Mexico's landforms, you have the coast, then a mountain range, then a BIG valley/basin, then another mountain range, and finally the other coast. </span>
Answer
16
or 50.24 units
Explanation:

and r is the radius, since we know what the radius is (<em>r </em>) we can put this in to an expression
· 4² = 16 units
If the answer is not 16 then its 50.24 units
Explanation:
Now 16 is the correct answer but just in case I took this a step further.
If we estimate the area by using 3.14 which is (
) because sometimes that isn't natural to express the area using

The statement "Mass extinctions have occurred several times on Earth" explains the indication of the fossil record.
<h3>Indication of Fossil fuels:</h3>
Paleontologists are fascinated by the evolution and extinction of fossil species throughout geologic history. To do so, they look at all the fossils that have been preserved in sedimentary rocks.
The fossil record is what we call it. Paleontologists have been collecting fossils from sedimentary rock layers all over the world for over two centuries.
Their goal is to figure out how species have evolved over geologic time. It can be used as a geologic timescale once the succession is established.
Then, if a specific fossil is discovered in a rock, you can determine where it belongs on the geologic timescale.
Therefore, the correct option is the third sentence.
