Solar
energy as radiation is nearly 150 million kilometers separate the sun and earth
and it drives earth’s weather. Earth’s atmosphere is 99% atmospheric gases,
including water vapor, extend only 30 kilometers (km) above earth’s surface. Atmosphere
gases include nitrogen, oxygen, argon, water vapor, and carbon dioxide are
invisible. Variable and increasing gases; nitrogen and oxygen concentrations
experience little change but carbon dioxide methane and oxides of nitrogen are
greenhouse gases experiencing increasing in concentrations C02 have raised more
than 18%. Atmospheric Greenhouse affects the warming of the atmosphere by
absorbing and emitting infrared radiation and allowing shortwave infrared
radiation to pass through. The main gases responsible for the greenhouse effect
are water vapor and carbon dioxide. Aerosols are human and natural activities
displace tiny soil salt and ash particles as suspended aerosols. Pollution are
sulfur and nitrogen oxides, and hydrocarbons are emitted as pollution. Lapse
rate is the rate at which air temperature decreases with height. In average
lapse rate in the lower atmosphere is about 6.5 degrees (*) per 1 km or 3.6 *f
per 1000ft. Urban heat island effect occurs when a metropolitan area is warmer
than the surrounding rural areas. UHI effect is caused primarily by
modification of land surfaces in developments that use materials that retain
heat. The cloud triangle: Clouds can be defined by: Their shape & form: The
cloud base altitude: If they are precipitating. Air pressure: Warm air-expanding
or rising: Air-leaves behind L pressure: Cold air-sinking air=leaves an H
pressure. Wind movement uneven heat of the earth’s surface causes some areas to
be warmer than others. Warm always
follows cold to share its warmth- when this happens in the atmosphere, wind
happens. Pressure, wind and weather, the winds are horizontal flows of air;
winds blow from areas of high pressure to areas of low pressure. Pressure
describes the tendency of the air to rise or to sink at any given place or
time. Humidity measure of the amount of water vapor stuck between molecules in
the air and the airs ability to hold water depends on the air temperature. Relative
humidity amount of water vapor (%) compared to the amount the air can hold and 100%=
air is saturated.

Ozone
What
is surface temperature? How
does ozone both enable life on Earth and threaten it? How
does the surface ozone form? How
does the surface ozone affect health?
Ozone
occurs naturally in Earth’s atmosphere wherever sunlight or chemical reactions
break apart oxygen molecules. The
ozone layer protects Earths inhabitants from the harmful rays of the sun. It’s harmful
because it can break down and leave gaps through the ozone and this allows
harmful rays through to the Earth’s surface. It
is a product of air pollution, also called smog. Breathing ozone can trigger a
variety of health problems including chest pain, coughing, throat irritation,
and congestion. It can worsen bronchitis, emphysema, and asthma. Ground level
ozone also can reduce lung function and inflame the linings of the lungs.
Repeated exposure may permanently scar lung tissue. The VOC is made up of volatile organic compounds. For example paints, varnishes, wax, fuels, cleaning, disinfecting, cosmetic, degreasing, and hobby products. The NOx made of nitrogen oxide gases. Also a group of highly reactive gases. The reaction of VOC and NOx forms surface ozones.

My Relationship
Well me and my boyfriend has be dating for a year. We have already broke up twice cause one he didn't go to homecoming with me and it made me so mad and i was like looking stupid cause everybody was asking about where he was, second time is when we was suppose to hang out and he went and chilled with his friend and he told me that we was haning out. I thought well if you want to hang with your friends you should tell me before its our day to hang out. I mean really your going to ditch me for your friends. But after all that we have been throw were doing great well kinda. He works a lot and its hard to see him cause he's always working and he don't have a phone and it sucks. We don't fight but we sometimes agrue. He don't like me hanging out with my guys friends and i told him that i hate hanging with girls and trust me i ain't going to try anything with my boys and i aint going to let them try anything on me and i mean it.

Hanging with your guy friends
Ok so if your a girl and you hang out with guys there's nothing thing wrong about that. Like me i hang out with boys all the time and i don't care if people say I'm a whore and stuff cause I'm chilling with your boyfriend don't mean I'm a whore and its not my fault that your dude wants to hang out with me and not you. My guy friends are only in the friend zone and they ain't ever getting in to the relationship zone. Girls are to much drama and i can't stand it and with boys there chilled and laid back but i understand if your guy friend try's to do something with you but you should be the person to say "naw we can only be friends and don't be trying anything cause we will not be friends". Well I'm done with this.
Later :)
Later :)
