LECTURE TOPIC # ONE: The Underpinnings of the Physical Sciences
This lecture contains basic information introducing physical geography and more about the natural laws that govern our physical world, how they relate to us in this course and other cool topics.

LECTURE TOPIC # TWO: Earth as a Planet
This lecture introduces the earth as it sits in our universe. Concepts include the geographic grid, the shape of the earth, the rotation of the earth, global time and most importantly an introduction to the earth-sun relationship.

LECTURE TOPIC # THREE: Global Energy Balance
This lecture introduces the concept of global energy balance, energy transfer and the global budget. Concepts introduced include: radiations, global insolation, composition of the atmosphere, global energy system, global energy budgets of the atmosphere and surface, net radiation-latitude and energy.

LECTURE TOPIC # FOUR: Air Temperature
This lecture introduces the concept of temperature. Concepts covered include: measurement, temperature Vs heat energy, atmospheric temperature profile, Surface temperature distribution, insolation receipt, the principle of continentality, elevation and air density and annual/global temperature patterns.

LECTURE TOPIC # FIVE: Atmospheric Winds
This lecture introduces the concept of atmospheric winds. Concepts covered include: Air pressure, measurement, vertical distribution, horizontal distribution, pressure gradients, the PGF, the Coriolis force, isobar maps, and pressure systems.

LECTURE TOPIC #7: Atmospheric Moisture and Cloud Formation
