For example, rising water temperatures are harming tropical coral reefs. The direct effect is coral bleaching on these reefs, because they are sensitive to even minor temperature changes. So a small increase in water temperature could have a significant impact in these environments. Another example is loss of sea ice habitats due
Earth science (also known as geoscience, the geographical sciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. [4] There are four major disciplines in earth sciences, namely geography , geology , geophysics and geodesy .
Biogeography (an amalgamation of biology and geography) is the comparative study of the geographic distribution of organisms and the corresponding evolution of their traits in space and time. [146] The Journal of Biogeography was established in 1974. [147] Biogeography and ecology share many of their disciplinary roots.
Predicated changes for Earth's biomes under two different climate change scenarios for 2081–2100. Top row is low emissions scenario, bottom row is high emissions scenario. Biomes are classified with Holdridge life zones system. A shift of 1 or 100% (darker colours) indicates that the region has fully moved into a completely different biome ...
In Earth science, it is common to conceptualize the Earth's surface as consisting of several distinct layers, often referred to as spheres: the lithosphere, the hydrosphere, the atmosphere, and the biosphere, this concept of spheres is a useful tool for understanding the Earth's surface and its various processes [30] these correspond to rocks ...
