The ocean plays a key role in the water cycle as it is the source of 86% of global evaporation. [2] The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, it takes up energy from its surroundings and cools the environment. When it condenses, it releases energy and warms the environment.
A drop of water can be in the ocean for years, or evaporate after a few days. Water is constantly changing and moving forms. Climate change can alter the life of a drop of water. With global warming, water evaporates faster and the cycle keeps moving at faster rates. The key here is the water cycle and how this works on a daily basis. [4]
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 ...
Many of the subsystems are characterized as "spheres", coinciding with the shape of the planet. The four spheres (for which most of the other spheres are a subtype of) are the atmosphere, the biosphere, the hydrosphere and the geosphere. Earth's ecosphere lies it self within the heliosphere (the Sun's astrosphere). [4]
Climate change is throwing the world's hydrologic cycle out of whack and promises big water problems in the coming years, climate scientist Peter Gleick told "The Climate Crisis Podcast."
Crash Course (sometimes stylized as CrashCourse) is an educational YouTube channel started by John Green and Hank Green (collectively the Green brothers), who became known on YouTube through their Vlogbrothers channel. [2] [3] [4] Crash Course was one of the hundred initial channels funded by YouTube's $100 million original channel initiative.
