Answer:
Extreme weather conditions
Polar ice melting
Acidification of oceans
Explanation:
Global warming is a phenomenon that refers to increase in temperature of the earth surface as a result of the concentration in the amount of greenhouse gases in the atmosphere. Greenhouse gases like carbon dioxide, methane, water vapour in their normal amount helps to trap some part of solar radiation which is useful for all life on earth. If the proportion of these gases increase beyond normal, more radiation will be trapped and a surge in surface temperature results. This increase in temperature leads to:
- Extreme weather conditions: Hurricanes, tornadoes becomes more prevalent as there is more heat in the atmosphere.
- Polar ice begins to melt as a result of increase in the temperature of the earth surface.
- Due to surge in the amount of carbon dioxide on the earth, the ocean dissolves the gases and this leads to the formation of weak carbonic acid.
Answer: a circle and uniform motion
Explanation:
Ptolemy's model of the universe placed the Earth motionless in the center of a universe subject to uniform circular motion, the other planets, the Moon and the Sun describe complicated orbits around it.
As Ptolemy was a respected astronomer and geographer, this idea was accepted for a long time, until Copernicus arrived with the new model (heliocentric theory) that placed the Sun at the center wir the Earth and other planets describing circular orbits around the star. However, <u>the heliocentric theory did not explain why planets orbit the Sun at different speeds at different times, because this model used only circular orbits in uniform motion. </u>
All of this is due to the Greek ideologies of perfect form and motion with a perfect circle. But then, the astronomer Johannes Kepler refined the Copernicus' heliocentric theory with the introduction of <u>elliptical orbits.</u>
