When the volcanoes erupted the gas from it made clouds and when it rained it started to for layers of water and that's how the first oceans formed......i think
The first person to use fossils for dating rock layers was William Smith, an English geologist and surveyor, in the early 19th century. He developed the principle of faunal succession, which recognized that different layers of rock contained distinct fossil assemblages that could be used to identify and correlate the relative ages of those layers. His pioneering work laid the foundation for modern stratigraphy and paleontology.
the first one to identify electrons as particles is Rutherford
He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in layers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
Robert Hooke was the first to identify the cell of a nucleus.

photosynthesis
The first dichotomous key is generally credited to Theophrastus, a Greek philosopher and scientist from ancient Greece. He created a system to identify plants based on specific characteristics in his work "Enquiry into Plants."

The Earth's atmosphere is composed in FIVE different layers. The first one is the Troposphere, which is the closest to the Earth's surface. The second one is the stratosphere. The third atmosphere is called the mesosphere, which contains the coldest air temperature. The forth is thermosphere, which contains the ionosphere that are made up of electrically charged particles (note that the ionosphere is not one of the atmosphere). The last part of the atmosphere is the exosphere, which is the region of the space travel. It is also the furthest atmospheric layer from the Earth.
Vostok I.
I would say he is like an onion because he has many layers he even said so himself in the first shrek movie. He may seem like a scary mean monster but he is actually very sweet and nice.
