Answer:Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.
Explanation:
This problem is based on the Greenhouse effect.
CO2 is one of the Greenhouse gases.
Gasoline and diesel cars gasoline burns fossil fuel and produce a lot of CO2 increasing the Greenhouse effect.
The sentences of the statement for the this case may be ordered to describe very well what happens with the fossil fuels and their effect in the planet.
This is the right order:
1) fossil fuels burned to run vehicles release co2
<span>2) CO2
traps heat and warms the atmosphere.
</span>
<span>3) The global surface temperature increases
4) ice and snow in
polar regions melts.
5)</span><span><span> large amounts of freshwater flow into

Answer:
Humans were nomads. Their wandering was mainly in search of food and shelter. When they found that certain places had an abundance of food – plant food or animals for hunting, they stayed on. They observed the plants, their growth and when these food sources diminished, they grew plants themselves, from the seeds they collected. This is how agriculture came about.
When humans stopped their nomadic ways and stayed together, it paved the way for formation of the human social structure. Hierarchies were established in due course.
