The difference between the fertility rate and the death rate corresponds with the birth rate. When you take the number of children that have been born (alive) in a given year, and then minus the number of the people that have died in the same year, you get the birthrate. It can be positive, when there's more born children than people that died, or negative, when there's more people that died than born children.
Index fossils, intrustions and cross-cutting relationships.
Explanation:
The correct list of three different geologic features that help scientists determine the relative ages of rocks by their position is "index fossils, intrusions, and cross-cutting relationships".
Scientists are of the opinion that global warming is a root cause of prolonged human interference with the natural environment and its due to the natural environment is contaminated by people and their technology the scientist all around the world are focusing on the positive and negative effects of climate change.
This change that has brought by the artificial use of nature by man for his survival and destruction of the earth that the Holocene epoch is going to create when it ends will be fatal for the planet.
henceforth science has made research labs around remote corners of the world trying to study sensitive environments and gather data and estimate the seasonal variations and fluctuations in patterns of the landscape from ice to land and then to water and then to complete transformation of the earth.
