Because scientists are so picky they needed to be seperated.
Density of air decreases on increasing height, hence we categorize the atmosphere into different layers from Troposhere to Ionosphere at particular kilometers respectively.
The atmosphere is divided into layers based on temperature changes with altitude. The five primary layers are: troposphere (where weather occurs), stratosphere (contains ozone layer), mesosphere (coldest layer), thermosphere (where auroras occur), and exosphere (outermost layer). Each layer has unique characteristics and serves different functions in maintaining Earth's climate and protecting life on the planet.
because you're gay
The layers of rock that indicate Earth's eras are divided into three main types: igneous, sedimentary, and metamorphic rock layers. By studying the rock layers and the fossils contained within them, scientists can determine the different eras of Earth's history, such as the Paleozoic, Mesozoic, and Cenozoic eras. Each era is characterized by distinct types of fossils and geological features preserved in the rock layers.
the reason why a rejected hypothesis can still be of value to a scientist is because that secific hyothesis may not work for your experiment but it could work for a different experiment/theory
One wold not describe the anatomy of an Earthworm in terms of "layers". For this reason we do not understand what you are asking.
its to old
It is to old
To find answers to their questions
Scientist can use the computer for many reasons one reason is to look up information for an experiment.
the reason why its gray is because its old and they layers are starting to show
because of his hard work and he was a scientist
