ACIDS AND BASES

Acid rain
Acids rain happens when the fumes go out of a factory and are sucked up by clouds then carried away and let out in the form of rain.

Effects :
It can hurt plants and animals it sucks the nutrients out of plants and then they die

Fair warning:
Next slide contains some graphic images of animals look away if you want ( I won't judge )

EFFECTS ON STATUES AND ANIMAS

Effect on animals :
The plants die and the animals have less food start fighting over food and then killing ?!?!

REGULAR ACIDS

ACIDS

• They have a sour terrible taste
• Not all are harmful
• Opposite of bases
• They give off H+ ions

BASES

BASES

• Opposite of acids
• Receive H+ ions
• Low on PH scale (after 7 )

WAVES / RAYS

Waves / rays in order
Shortest to longest :
1: gamma rays
2:X-rays
3: ultraviolet
4: infared
5: microwaves
6: radio waves

GAMMA RAYS :

• Small wavelengths
• Most energy
• Generated by radioactive atoms
• Can kill living cells
• But doctors can use them to kill diseased cells

RADIO WAVES :

• Longest wave length
• Carry lots of signals!!!
• Examples: news,tv,cellular,

INFARED :

• Long wavelengths
• Also short wavelength
• Can be detected as heat

VISIBLE LIGHT :

• The only electromagnetic waves we can see
• As the colors of the rainbows
• Every color has a different wave length
• Red has the longest
• Some insects can see

X-RAYS :

• Smaller wavelengths
• Doctors use them to see our bones
• Can damage important parts of reproduction
• Pass easily through skin

UV RAYS :

• Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light
• Found in sunlight and it is emitted by electric arch
• Causes many items to glow purpleish

OZONE

• The ozone protects us from harmful sun rays
• Has a sharp odor
• Earth stratosphere
