Greenhouse effect and global climate change

Question 1

Greenhouse effect

Answer 1

short wavelengths radiation passes through the atmosphere, short wavelength radiation absorbed by the earth’s surface, long wavelength radiation emitted from Earth’s surface, some long wavelength radiation escapes into space, greenhouse gases absorb long wavelength radiation, atmosphere warms up

Question 2

How have humans led to global climate change

Answer 2

increasing greenhouse gases - CO2 =combustion of fossil fuels, deforestation - Methane = animal farming, decomposing organic matter in landfills

Question 3

Effects of global climate change

Answer 3

ice caps melt -> sea levels rise -> coastal flooding -> loss of land, extreme weather -> flooding/drought -> damage to crops -> loss of habitat
