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.

Explanation: The moon changes its visual position relative to the earth during one night because the earth revolves around its axis. As the earth revolves around its axis it means that within a few hours an observer at a certain point on earth will, due to the earth's rotation, change the angle at which he sees the moon.
The fact that the moon also moves, that is, rotates around the earth, and that it takes about a month for a full rotation around the earth, is why we will see the moon in a different position in the sky at the same time next night.
Answer:
Lines of latitude measure north-south position between the poles. Lines of latitude are all parallel to each other, thus they are often referred to as parallels.
Lines of longitude, or meridians, run between the North and South Poles. They measure east-west position. The prime meridian is assigned the value of 0 degrees, and runs through Greenwich, England. Meridians to the west of the prime meridian are measured in degrees west and likewise those to the east of the prime meridian are measured to by their number of degrees east.
An Isosceles triangle has two even parts, you add them up. For example 60 degree plus another 60 degree angle is 120 degrees. And the limit is 180 degrees, so in order to get that last angle, you'd have to subtract 160 from 180. And that'd be 20 degrees. I couldn't see the question but I hope this helps you in a way
It would be true because the Mayans originated in between those areas
