Answer:

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions.

Yes earth needs a greenhouse effect to support life .

When the solar radiation falls on the earth's surface, put of the radiation is absorbed and a part is reflected back inte space. Greenhouse gases like carbon diraide and methane present in the atmosphere absorb some of the radiated heat. These trapped radiation further warm the earth The trapping of the sun addition by the gases present in the urthi atmosphere is called greenhouse effect. Without the natural greenhouse effect, life would not have been possible on the carth because in the absence of such an ctfect the cu surface would have been too cold to sustain life.

Many aspects of global climate are changing .High temperature extremes and heavy precipitation events are increasing, glaciers and snow cover are shrinking, and sea ice is retreating. ... Greenhouse gas emissions from human activities will continue to affect Earth's climate for decades

currently due to the use of many vehicles , fossils etc a lot of pollution is caused and concentration of CO2 (carbon dioxide ) has increased which is causing the earth to become to hot which is leading to melting of glaciers which causes global warming .

hope you've understood ☺️

topjm [15]

Answer:

C. Sprout every year, year after year

Explanation:

The perennial plants are the plants that live for more then two years, thous some may argue that they are plants that live more then three years. Whichever the case, they are not short-lived plants, but are capable of surviving for numerous years, unlike the annuals and biennials. Theoretically, the shrubs and trees would fall into this category, but they are classified separately, and this term is not used for them, but for smaller plants that do not have or have very little woody parts. These plants tend to sprout every year, and even though they seemingly die in the autumn, their roots are alive, and they emerge and grow again in the spring, sprouting again. That process repeats itself for numerous years.
