Why does the frost depth increase when the surface temperature warms up?
WinterAsked by: Alyssa Lynn Why does frost go deeper when it warms up? That’s is due to the slow diffusion of heat into the ground. Unlike a liquid, pieces of soil can’t move around, therefore, in the absence of liquid water, heat can only be transferred by conduction, a process that follows the diffusion equations
Is there a software or means that can generate piper diagrams without some data?
VisualizationAsked by: Alyssa Lynn How do I create a Piper chart in Excel? Quote from video: Click home new graph turnery piper plot in the open worksheet dialog select a new or open data file and click open the plot is created to create a piper class scatterplot. How do you make a Piper plot?
How is surface pressure generally measured, and at what actual height?
Earth scienceAsked by: Jenny Robinson How do you measure surface pressure? Calculate surface pressure: P=F/A The force is distributed over the entire bearing surface. All that’s left to do is to divide the force by the calculated area to get the surface pressure. Which height is a measure of atmospheric pressure? One atmosphere (101.325 kPa or
Is the iron on Earth’s crust a leftover of the Iron catastrophe, or it was brought back by volcanoes?
Earth scienceAsked by: Jenny Robinson So Iron is indeed a leftover of the iron catastrophe, and the reason why that fraction didn’t sink is because it was oxidized. Where did the iron in the Earth’s core come from? Billions of years ago, the newborn Earth morphed from a messy ball of mixed-up rock to a perfectly
How long ago was the first limestone formed?
Earth scienceAsked by: Paul Reggae Limestone is found in sedimentary sequences as old as 2.7 billion years. However, the compositions of carbonate rocks show an uneven distribution in time in the geologic record. About 95% of modern carbonates are composed of high-magnesium calcite and aragonite. How was limestone first formed? Limestone has two origins: (1) biogenic
What are the dominant elements that oxygen is bonded to on earth?
Earth scienceAsked by: Paul Reggae Oxygen is dominantly found in silicate minerals which, aside from silica, contain other elements. One way of looking at the chemical form of oxygen is to look at its bonds within the compounds. What element does oxygen bond with? Oxygen is reactive and will form oxides with all other elements except
Did the surfaces of the oceans freeze over entirely during the snowball Earth periods?
Earth scienceAsked by: Randy Gray What ended the ice age? New University of Melbourne research has revealed that ice ages over the last million years ended when the tilt angle of the Earth’s axis was approaching higher values. What caused the ice age 10000 years ago? The onset of an ice age is related to the
How fast is the Gulf Stream near shore?
Earth scienceAsked by: Randy Gray 5.6 miles per hournine kilometers per hour (5.6 miles per hour). How far from shore is the Gulf Stream? The Gulf Stream stretches 40 to 50 miles wide off the coast of southeast Florida as it chugs and snakes, ultimately toward Iceland, at a clip of 2 to 4 miles per
How common is it for warm fronts to be responsible for record high temperatures?
Earth scienceAsked by: Dustin Bennett What is warm front in meteorology? A warm front forms when a warm air mass pushes into a cooler air mass, shown in the image to the right (A). Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds
How to find latitude and longitude?
Earth scienceAsked by: Dustin Bennett Get the coordinates of a place On your computer, open Google Maps. Right-click the place or area on the map. This will open a pop-up window. You can find your latitude and longitude in decimal format at the top. To copy the coordinates automatically, left click on the latitude and longitude.
