GGR100H1 Lecture Notes - Lecture 2: Atmospheric Circulation, Surface 3, Seafloor Spreading
Document Summary
Outline: two primary elements of physical geography, part 1: from the sun to the earth"s surface, part 2: below the earth"s From the sun to the earth;s surface: solar radiation a. i. Electro-magnetic (em) energy from the sun is commonly known as sunlight. Benefits of sunlight: visible light, photosynthesis, atmospheric circulation. Wavelength: the spatial period of sinusoidal (sine) wave. Frequency : time interval between the waves (frequency of particles travelling around the wavelength) wavelength is long low frequency (inverse relationship) Wavelengths of all the solar radiation coming into our planet characterized by wavelengths e. g. radio/micro waves, and short ones e. g. by wavelengths e. g. radio/micro waves, and short ones e. g. x-rays and gamma rays. Properties of each diff. wavelength of radiation, use them to help us. Visible light spectrum between infrared and ultraviolet. Part of the em spectrum visible to the human eye. Diff wavelengths can be in diff groupings: movement in space. Tilt, rotation, procession and how it affects the climate.
