CHEMISTRY OF THE ATMOSPHERE PART III

•light is absorbed by chlorophyll a molecules bound to reaction-center proteins in the thylakoid membrane. The energized chlorophylls donate an electron to a quinone on the opposite side of the membrane, creating a charge separation. In green plants, the positively charged chlorophylls then remove electrons from water, forming oxygen.

• STAGE 1

• STAGE 2

• STAGE 3

• STAGE 4

The process by which green plants and certain other organism transform light energy into chemical energy.

• Photosynthesis

• Oxygen Cycle

Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called

• chlorophyll

• Carbon

• oxygen

• water

It is the Earth's solid outer layer. It consists of the brittle top section of the mantle and the crust.

• Lithosphere

• Mesosphere

• Asthenosphere

• Barysphere

It is composed of those areas of the planet where life may be found.

• Lithosphere

• Biosphere

• Ocean Trench

• Universe

It is the process of moving oxygen across the Earth's three major zones, the Atmosphere, Biosphere and Lithosphere.

• Water Cycle

• Oxygen Cycle

consist of gases, liquids, or solids present in the atmosphere in high enough levels to harm humans, other organisms, or materials.

• Water Pollution

• Land Pollution

• Air Pollution

• Noise Pollution

This is formed when pollutants such as nitrogen oxides and volatile organic compounds (VOCs) react in sunlight.

• Ground Ozone

• Ozone Layer

• Grand Ozone Layer

• Ground Level Ozone

Type of Air Pollution which is one of the most critical global environment problems, probably exposes more people worldwide to important air pollutants than does pollution in outdoor area. 

• Indoor Air Pollution

• Outdoor Air Pollution

One of the first environmental agreements to formally recognize the precautionary principle. Related actions taken consistent with this principle have included the preemptive decision to ban new ozone depleting substances before they were ever produced commercially.
