Nuestra prioridad es ofrecer una comunidad segura para nuestros usuarios creando relaciones basadas en el respeto.This series shows the physical processes and human activities that shape our planet.This program introduces the topic of geophysics, exploring methods of studying what lies beneath Earth's surface.Geophysicists use seismic wave studies, variations in temperature, magnetic fields, gravity, and computer simulations to create models of deep structures. The Sea Floor The mysteries of the ocean floor lie hidden under enormous pressure and total darkness.It also looks at tectonic force and the different types of stress involved in the formation of geologic structures. Earthquakes Showing actual footage of earthquakes and their aftermath, this program discusses the forces that fuel these massive events.
Animations illustrate volcanic processes and how plate boundaries are related to volcanism. This magma seeps into crevices in existing rock to form intrusive igneous rocks.A relationship between this timeline and that of life on Earth is established, with fossils and radiocarbon dating playing a major role in the discovery. Evolution Through Time The fossil record reveals much about the diversity and development of species.This program examines the traces left by early plants, animals, and single-celled organisms and follows the progression of life forms over time.Connections are drawn between atmospheric gases, climate change, rock formation, biological functions, and mass extinctions. Minerals: The Materials of Earth Minerals have been indispensable to human civilization.This program looks at the variety of minerals, their atomic and crystalline structures, and their physical properties such as hardness and luster.
