They explain how the relative positions of Earth, the sun and moon affect phenomena on Earth. They analyse how the sustainable use of resources depends on the way they are formed and cycle through Earth systems.
Understanding solid Earth phenomena, including the formation and evolution of tectonic plate boundaries, requires an insight into the physical conditions (e.g., stress) of the geological settings at which these phenomena occur.
Earth scientists use the structure, sequence, and properties of rocks, sediments, and fossils, as well as the locations of current and past ocean basins, lakes, and rivers, to reconstruct events in Earth’s planetary history.
Life began on Earth at least 3.5 billion years ago. Since then, it's diversified in an amazing way! Learn about important events in the history of living organism on Earth, up to and including the appearance of humans.
The solar system is made up of the Sun, the planets that orbit the Sun, their satellites, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can see these movements.
23 de abr. de 2018 · Humanity faces the question of how such massive losses of species diversity will affect the complex ecosystems that sustain life on Earth, including our ability to derive the foods, biomaterials, bioenergy, and medicines necessary to support an expected human population of 9.6 billion by 2050.
5 de feb. de 2020 · We discuss how it maps onto evolving planetary surface environments on early Earth and Mars and the value of comparative planetary evolution. The results indicate that Mars can offer direct evidence for geochemical conditions similar to prebiotic Earth, whose early record has been erased.
