In my problem there is an average net ecosystem production rate of: 0.25 kg$^o$C/m2/yr Am asked: a. What percentage of 140,000 tons/yr would be offset from reforesting 45,000 acres? b. With ...

While hiking Hyndman Peak in Idaho a couple weeks ago we noticed a rock slide that appeared to be formed by a glacier, however it was on the west side of the mountain. It was also strange that the ...

I am trying to download transpiration and snow cover data from earth data but unable to figure out how to do that

A nice picture for "how mountains formed" on Earth is due to the motion of tectonic plates. As the plates crash together, mountains may get "pushed upwards". However, a quick look at a map of the ...

When discussing a hypothetical world without oceans and just forest it occured to me that I wasn't so sure there would be any rain in the first place, due to the lack of oceans. Searching on Google ...

I found spherical or globular structures, structures in basalts of a greenstone belt which underwent alteration and deformation. However, in thin section, these structures have undeformed pyroxene and ...

We can calculate the maximum possible height of the mountain on earth. If the elastic limit of a typical rock is $3 \times 10^8\ \mathrm{N/m}$ and its mean density is $3 \times 10^3\ \mathrm{kg/m^3}$,...

An oxidizer, fuel, and heat are needed for a fire. When considering oxygen as the oxidizer, an oxygen concentration of approximately 16% is required for combustion. Plant material is the fuel ...

For many years there are terrible forest fires in the U.S. (for example); I was wondering about pro-active measures ( I'm sure there are many). One possibility is using a small army of robots that are ...

Following recent eruption of Mt Ontake and the sad news of over 30 people found in 'cardiac arrest', why would the eruption cause it? My initial thought would be that the cause of death would ...

I've seen some videos of people scooping up some water from a natural body of it, adding some sand and a few plants, and soon enough, they have a (near) self-sustaining aquarium. I've always wanted to ...

When the Earth was at its warmest, and there were no ice caps at all, not even during the winter, and thermal expansion meant a certain amount of water took up more space, what ratio of Earth's ...

So the first problem I'm stuck on is this one: 1.An airmass is moving down a mountain from point A to B.At A the temperature is -10 celsius and the pressure is 890hPa. At point B the pressure is 1010 ...

I have been doing some DIYnamics with rotating water and non-rotating water. So I had a bucket filled with water on a rotating table, and waited for it to be in solid body rotation. I then dropped ...

How can South Africa’s location contribute to the worldwide interpretation of landscape evolution?

I was working with SO2 column data product from https://disc.gsfc.nasa.gov/datasets/OMSO2_003/summary?keywords=OMI%20Total%20Column%201-Orbit%20L2%20Swath I wanted to know, is the cloudfraction data ...

What percent of the Earth's core is uranium? And how much of the heat at the core is from radioactive decay rather than other forces?

Many algorithms in remote sensing take one or more different datasets as inputs and return some output. An example might be computing the amount of sulfur dioxide (SO2) injected into the stratosphere ...

A hot molten core is important for making the Earth geologically active. I believe most of the heat is from the time of the planet formation, and the high pressures due to everything pushing down to ...

I noticed that Paulette (2020) is still a named storm and is now approaching northern Africa and Spain. It is forecast to begin moving west again in the coming week. Has a hurricane / tropical storm ...

I am exploring FLUXNET sites for actual evapotranspiration (ETP) data (I convert the energy balance closure-corrected latent heat to ETP). I am interested in the half-hourly data. During the night we ...

I am attempting to interpret an outcrop I went to. I suggested it was created by a braided fluvial. The one thing I cannot explain are prominent alternating siltstone beds with the sandstone beds. ...

I have been fascinated by photos of these for a while, and I would like to ask how megaspherulites grow so large, when spherulites are normally quite small? I also noticed that all papers about the ...

How do scientists confirm iron core at the centre of the earth? We know scientists couldn’t yet drill to the core of our planet earth. Yet we know they confirmed there is a core of iron at the centre ...

These limestone-clay rocks are very common in the Alps, they come from weather changes. How many years does it take to make one of the rock bands? 7 years, equivalent to an el-nino type event? 1000 ...

I have some set of recorded data in dip direction/dip format. I wish to transform then to strike/dip. I am currently having a hard time imagining how to convert from dip direction to strike direction. ...

There is much known about Earth's core from painstaking analysis of seismic data, and from detailed magnetic field maps and trends over time. Are there any other measurements that have contributed to ...

Assuming the sea levels were lower, before the displacement of 200m of sand globally... Roughly what would be the sea level 'before' this event, assuming it already happened? (Looking for a rough &...

Why are there no giant nickel porphyry deposits like those of copper, or SEDEX deposits, like those of zinc? Why is all the nickel found in direct magmatic intrusions from the mantle to the surface? ...

Take something like the Bermuda High, for instance. I drew a crude illustration of it. It steers hot, humid air from the Gulf of Mexico towards the east coast of North America. But upper level winds ...

Take a look at this picture. Moist updrafts interact with highly-sheared upper-level winds, which sets up a horizontal vortex. But why? What causes the air to be forced downward and to the right, then ...

From what I read all over the web and articles, drainage density is a parameter that is defined for a catchment. I want to use a hydrological model to simulate the percolation from the bottom of a ...

Please explain the main differences between Climatology, Meteorology and Atmospheric Science. Thank you

Some basic differences are needed for children to understand only. The language should be simple enough so that any age understands for 5 to 99 or maybe 100.

Tsunamis can be caused by underwater earthquakes, like the 2004 tsunami in the Indian Ocean. The precise value will likely depend on where the earthquake is relative to the coast. But what is the time ...

Why does the same temperature feel hotter at night? For example, 70 degrees literally feels hot at night when outside but during the day 70 degrees feels just mild when outside. Why is that? And ...

Traditionally we think of them as being caused by differences in land-sea heating. But more recently, some researchers, like Simona Bordoni and William Boos, have argued otherwise.
