Greenhouse effect

Question 1

What is electromagnetic radiation..

Answer 1

waves through the electromagnetic field .. some can be seen some can not

Question 2

What are the 6 different types of electromagnetic radiation and how they interact

Answer 2

gamma rays – pass through people and buildings -uncommon in everyday
x-rays; pass thru flesh - absorbed by bone
ultraviolet – sunnnburnn - dna absorbs asf
infrared – wavelength too long to see – in greenhouse effect
microwave - heats water in food - food absorbs heat
radiowaves – travel easy thru atmosphere & buildings

Question 3

What are you looking at in the blue sky?

Answer 3

The reflection of blue light and absorption of other colors

Question 4

how do the wavelengths of ultraviolet radiation, red light, green light, violet light, and infrared radiation compare.

Answer 4

Ultraviolet = shorter wavelength than violet light
Infrared = longer wavelength than red light
green is a middle vibe of visible light

Question 5

Physics principle 1;

Answer 5

sunlight is a type of electromagnetic radiation

Question 6

Physics principle 2;

Answer 6

when photons encounter something they will reflect, absorb or transmit

Question 7

Physics principle 3;

Answer 7

each substance reflects absorbs and transmits specific wavelengths of electromagnetic radiation

Question 8

Physics principle 4;

Answer 8

all objects emit em radiation with a wavelength depending on their temperature

Question 9

Physics principle 5;

Answer 9

energy is never lost; absorbing radiation will warm an object

Question 10

describe how infrared radiation differs from visible light, why Earth emits it, and how it interacts with the atmosphere

Answer 10

infrared has a longer wavelength therefore can not be seen, earth emits it or else it would continue to get warmer and warmer, it enters the atmospehre some gets absorbed by surface, some goes back into atmosphere and goes to space or gets trapped by CO2 and gets sent back to earth

Question 11

Four most common gases

Answer 11

Nitrogen - 78%
Oxygen - 21%
Argon
carbon dioxide

Question 12

Describe Greenhouse effect

Answer 12

Sun - emits solar radiation - some is reflected - about half is absorbed by the surface and warms it – infrared radiation is emmited from surface - some passes thru atmosphere but most is remitted in all directions by gg (CO2) and clouds – causing warming of the earths surface

Question 13

describe the relationship between the greenhouse effect and global warming.

Answer 13

Global warming is caused by humans which is increasing the amount of CO2 in atmosphere with strengthens greenhouse effect – more infrared radiation gets trapped and sent back to earths surface
