Earth scienceAsked by: Reed Laskowski Ferdinand MagellanFerdinand MagellanFerdinand Magellan (/məˈɡɛlən/ or /məˈdʒɛlən/; Portuguese: Fernão de Magalhães, IPA: [fɨɾˈnɐ̃w dɨ mɐɣɐˈʎɐ̃jʃ]; Spanish: Fernando de Magallanes, IPA: [feɾˈnando ðe maɣaˈʎanes]; 4 February 1480 – 27 April 1521) was a Portuguese explorer and a subject of the Hispanic Monarchy from 1518. Who first discovered the jet stream? Wasaburo Oishi

Erosion without weathering?
Earth scienceAsked by: Reed Laskowski Can there be erosion without weathering? Without weathering, erosion is not possible. Because the two processes work so closely together, they are often confused. However, they are two separate processes. Weathering is the process of breaking down rocks. What causes erosion but not weathering? Wind, water, ice and human activities are

Geological maps of British Columbia
Earth scienceAsked by: Curtis Cavenaugh What is the geological history of British Columbia? British Columbia is composed of a portion of the ancestral North American Craton as well as two superterranes that were appended to the continent during a pair of Mesozoic collision events. The Coast Range Batholith intruded into the Insular Superterrane about 100 million

Locate people by Oxygen/Carbon Dioxide levels
Earth scienceAsked by: Curtis Cavenaugh Why do we measure CO2 in patients? The CO2 test is most often done as part of an electrolyte or basic metabolic panel. Changes in your CO2 level may suggest that you are losing or retaining fluid. This may cause an imbalance in your body’s electrolytes. CO2 levels in the blood

How will sea level rise be distributed across the globe?
Earth scienceAsked by: Carrie Bendinger Do sea levels rise equally around the world? No. Sea level rise is uneven, the two main reasons being ocean dynamics and Earth’s uneven gravity field. First, ocean dynamics is the redistribution of mass due to currents driven by wind, heating, evaporation and precipitation. How much will the sea level rise

How does the lapse rate in clouds compare with the lapse rate of air?
Earth scienceAsked by: Carrie Bendinger How does the lapse rate typically compare between the inside and outside of a cloud? The lapse rate of temperature is ignorant of clouds, it only cares that either e/es=1 (moist), where e is vapor pressure and es is saturation vapor pressure. A cloud is saturated (and in places supersaturated) and

What does the precessional parameter measure?
Earth scienceAsked by: Tim Lakemary What is the precession index? The precession index is e sin omega(sub s) where e is the Earth’s orbital eccentricity and omega(sub s) measures how close the Sun is to the Earth at midsummer. When omega(sub s) = 90deg the Sun is close to the Earth during northern summer, and at

Equations for Global Temperature Models
Earth scienceAsked by: Tim Lakemary How is global temp calculated? To calculate global temperature, researchers average the readings for each grid point, weighted by the area associated with that grid point. Latitudes further away from the equator have smaller areas. What is the fundamental equation on which climate models are based? The most important of these

Specific humidity range in tropical lowlands?
Earth scienceAsked by: Rudy Wall What is the range of specific humidity? According to Ahrens (2007), the average specific humidity ranges from 0.004 kg/kg at 60 degrees (north or south) to 0.018 kg/kg at the equator. Since these are only average values, it is possible to have higher or lower values depending on the specific environmental

What actually happens to reduce the perceived color in a ‘white rainbow” or “fog-bow”?
Earth scienceAsked by: Rudy Wall Why are fog bows white? The droplets’ small size is the reason fog bows are pure white. Rainbows form when light enters raindrops and gets diffracted and scattered in a very organized manner, which separates it into the colors of the visible spectrum. Fog drops are too small to achieve this.
