Which is a way that paleontologists have contributed to humans' understanding of the history of life? They found evidence that climate has not changed significantly.
They grouped organisms by the period in which they existed.
They discovered that the first humans lived with dinosaurs.
They learned that life has existed since Earth was created.

The correct answer is They grouped organisms by the period in which they existed.

Explanation:

The job of a paleontologist is to understand the history of life on our planet by analyzing evidence such as fossils. This work has allowed paleontologists to understand the evolution of life on Earth from simple organisms such as bacteria to complex organisms such as mammals.

Moreover, this has been possible because, through different analyses, paleontologists can group the organisms they find by the periods in which they existed and this makes possible understand better the history of life including the approximate time first organisms existed, how these changed over time and how these led to the organisms that exist today.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
