GLOBAL WARMING:
Arise
in temperature all over the world, due to trapped gases in the atmosphere
.
GREENHOUSE EFFECT:
The heat trapping feature of the atmosphere. Without the Greenhouse
Effect,
the temperature on Earth would be so low, life as we know it would not
be able to exist!
PHOTOSYNTHESIS:
The process by which plants
convert
Sunlight to food = energy!!
REFLECTION & REFRACTION:
Reflection is the bouncing of light rays off an object (such as a building).
Refraction is when Light Rays pass through the object (such as glass or
water).
SOLAR POWER: Any
object that is powered by or partially powered by the Sun. We use
manysolar
powered objects now.
SUNSCREENS & OTHER SUN
PROTECTION: Products that protect humans and animals from the
harmful rays of the Sun. These include: Sunscreens,
umbrellas, hats, shades for homes and cars, sunglasses.
The SPF is the
ratio of the time required to produce minimal erythema [reddening of the
skin] on skin covered by a sunscreen product to the time required to produce
the same degree of erythema without the sunscreen. These scores are
determined indoors using artificial light sources and by applying a predetermined
amount of sunscreen over a defined area. Whew! Did you understand
that any better than me? Just use sunscreen with a high SPF kids! Protect
yourself from ICOG!
UV RAYS: Ultra
Violet Rays - These rays are from the Sun and can be harmful to humans
and animals. There are UVA, UVB, and UVC rays. There are many
places on the web you can get more information from. Just type in
UVA, UVB, UVC rays into a search engine on the www and travel the speed
of light to information! (That's 186,000 miles per second by the way)
