Answer:
The importance of rocks has been realized on the surface of earth since a long time because they provide information and knowledge about the surface on which they are found.
They also tell us about the species which are found on that place where these rocks are which gives a lot of knowledge to the scientists. Also these layers have minerals in them which are very important for the animals to have a healthy life and also the water present in them naturally.
Explanation: Tyrannosaurus rex lived in the late Cretaceous period. According to the chart and the geological time scale, mammoths lived in the late Cenozoic era. The rock layers support this fact because the mammoth is in the top layer. So, the mammoth fossil formed more recently than the T. rex fossil. This information also indicates that Tyrannosaurus rex and other dinosaurs lived before mammoths.

Observation 2: The stars appear brighter at different times of the year.
Which observation(s) can be explained using the heliocentric model?
A. Only observation 1
B. Only observation 2
C. Both observation 1 and observation 2
D. Neither observation 1 nor observation 2
Both observation 1 and observation 2 can be explained using the heliocentric model.
Nicolaus Copernicus was the one who proposed the heliocentric universe model. Since ancient times, numerous scientists have attempted to explain the universe. He may not have been the first to propose that an astronomical body serves as the universe's center. However, he stated that the sun, not the earth, was the center of the universe.
Additionally, it is surrounded by the earth. It can be found in his book on the Heavenly Bodies Revolutions. It was only made public while he was dying. The astronomical model of the Earth and its planets circling the Sun at the center of the universe is called heliocentrism, and it is also known as the Heliocentric model. By and large, heliocentrism was against geocentrism, which put the Earth at the middle.
