This lecture briefly focus on Global Warming Prediction. Calculate the carbon emitted due to burning fossil fuels and the CO2 concentration in the atmosphere, accounting for residence…

The temperature of the earth is directly related to the energy input from the Sun. Some of the Sun’s energy is reflected by clouds. Other…

Primary objective of this lecture is to present on Organic Ingredients. Organic molecules only absorb UV rays whose energy matches difference between electron energy levels. Different kinds of…

This lecture introduce on Good Ozone and Bad Ozone. Good ozone: In the stratosphere, absorbs 97+ % of solar UV, protecting life from harm. This “good” ozone shields life…

Venus surface is similar to Earth and Mars – few impact craters, volcanoes, and evidence of tectonics activities. But no plate tectonics. The volcanoes of Venus is…

Prime objective of this lecture is to present on Geology of Mars. The geology of Mars is the scientific study of the surface, crust, and interior of…

The mechanism by which Earth self-regulates its temperature is called the carbon dioxide cycle, or the CO2 cycle for short. If Earth warms up a bit,…

Earth’s atmosphere is slightly warmer than what it should be due to direct solar heating because of a mild case of greenhouse effect. The ground is…

General objective of this lecture is to present on Greenhouse Gases. Greenhouse gases absorb infrared radiation and prevent it from escaping to space. Carbon dioxide, methane, and nitrous…

The Earth’s surface thus receives energy from two sources: the sun & the atmosphere. As a result the Earth’s surface is 33C warmer than it would…

Principle objective of this lecture is to present on Spheres of The Earth. Everything in Earth’s system can be placed into one of four major subsystems: land,…

The hydrosphere contains all the water found on our planet. Water found on the surface of our planet includes the ocean as well as water from…
