When was the first not-icy desert formed?
Natural EnvironmentsUnearthing Earth’s Oldest Dry Spots: When Did Deserts First Appear? Deserts. Just the word conjures images of stark beauty, resilience, and maybe a bit of scorching heat. But have you ever wondered when these arid landscapes first popped up on our planet? It’s a question that takes us on a fascinating journey through Earth’s deep
How does high rate of evapo-transpiration contribute to the ineffectiveness of rainfall?
Earth ScienceAsked by: Brandon Bilima How does evapotranspiration affect precipitation? Evapotranspiration is an important process in the water cycle because it is responsible for 15% of the atmosphere’s water vapor. Without that input of water vapor, clouds couldn’t form and precipitation would never fall. What are the factors affecting evapo transpiration? The principal weather parameters affecting
Was Earth completely covered in Oceans prior to the onset of plate tectonics?
Earth ScienceAsked by: Brandon Bilima New evidence suggests the planet was covered by a vast ocean and had no continents at all. Continents appeared later, as plate tectonics thrust enormous, rocky land masses upward to breach the sea surfaces, scientists recently reported. Was the Earth initially covered in water? Earth may have been a water world
Geology: What’s make a group of bedrock a formation?
Earth ScienceAsked by: Chris Norton What is a bedrock formation? bedrock, a deposit of solid rock that is typically buried beneath soil and other broken or unconsolidated material (regolith). Bedrock is made up of igneous, sedimentary, or metamorphic rock, and it often serves as the parent material (the source of rock and mineral fragments) for regolith
“Five of the Solomon Islands disappeared” due to sea level rise, how is this possible so quickly?
Earth ScienceAsked by: Chris Norton What happens to islands when sea levels rise? As sea level rises, island nations are at increased risk of losing coastal arable land to degradation as well as salination. Once the limited available soil on these islands becomes salinated, it becomes very difficult to produce subsistence crops such as breadfruit. How
Persistence time of ozone
Weather & ForecastsOzone’s Vanishing Act: How Long Does It Really Stick Around? Ozone (O3) – that triatomic form of oxygen – it’s a bit of a Jekyll and Hyde character in our atmosphere. Up in the stratosphere, it’s our superhero, shielding us from the sun’s harmful UV rays. But down here at ground level? It’s a pollutant,
