Answer: Ptolemaic system, also called geocentric system or geocentric model, mathematical model of the universe formulated by the Alexandrian astronomer and mathematician Ptolemy about 150 CE and recorded by him in his Almagest and Planetary Hypotheses. The Ptolemaic system is a geocentric cosmology; that is, it starts by assuming that Earth is stationary and at the centre of the universe. The “natural” expectation for ancient societies was that the heavenly bodies (Sun, Moon, planets, and stars) must travel in uniform motion along the most “perfect” path possible, a circle. However, the paths of the Sun, Moon, and planets as observed from Earth are not circular. Ptolemy’s model explained this “imperfection” by postulating that the apparently irregular movements were a combination of several regular circular motions seen in perspective from a stationary Earth.

The answer is; greenhouse effect, insulating
Examples of greenhouse gases in the atmosphere are carbon dioxide and methane. They trap infrared light spectrum emitted from the earth towards space. This trap acts as heat insulation causing global temperatures to rise and resulting in global warming and climate change.
Population is the answer !
By pushing on the top of it and the water or substance will get into it
Homeostasis is the property of living organisms in which internal systems are kept in balance. Plants stay cool in the desert heat through their reflective surfaces, reduced leaves, or leaves that are parallel to the sun.
