Earth Science

Heard many times comments on volcanic solis being very rich yielding good cultivable areas. Heard other times, and seen myself volcanic soils being totally deprived of vegetation and life. How do both match ?

Hi: I am a retired Earth Science Teacher from Ohio. Our state has decided that Earth Science is no longer important and is taking it out of the high school curricula. After 30+ years of fighting to make Earth Science an acceptable class, I see the state DOE scuttling all my work. I was hoping some of you would be proactive in your states and try to not let this happen to you. Our kids NEED Earth Science. For 10 dollars you can join the National Earth Science Teachers Association. Get ideas and make your voice heard. http://www.nestanet....content/welcome I am also starting a Facebook Group for Earth Science Teachers. Join up and pass the word. Thanks. h…

This may seem weird to you guys but i have always wanted to do this as a kid. So here is my plan on digging a really deep hole, I might not make it to a 1000 feet but i want to dig as deep as i can, maybe even deeper than a 1000 feet. I will add some vents, and maybe rest rooms or rooms to put digging tools in. I dont plan on digging straight down, but kind of at an angle. I will reinforce the walls and ceiling, so it dont cave in If anyone has any tips or suggestions it would be greatly appreciated, like how will i make vents? and how will i get the dirt out when im hundreds of feet deep? I want to know if any one else has tried anything like this? What k…

what happens to a tsunami as it bends around a coast? Suppose it approaches an island from south to north.Does the South bear the brunt of the wave? Do the effects tend to lessen as the wave flows around the island? I seem to remember that the West Coast of Sri Lanka was very badly affected even though the wave approached from the East when the Christmas Tsunami struck. Would that have been down to local conditions magnifying the wave in particular area is the wave as well able to attack from the rear as from the front?

I'm learning about earthquakes in one of my classes and am unsure about what type of interactions at plate boundaries can cause them. Can earthquakes occur at a continental-continental convergent plate boundary? Or is mountain formation the only result when the continental plates collide?

Akward questions: 1. Approximatley how big does one average human stool expand too in measurement? 2. Approximatley how much of those one human stools would it take so that every little spec of the entire planets land (each continent) is covered with it? Hope to get benificial answers from the knowledgable users on ScienceForum.Net

This question came due to and explanation in my son's instruction material for his 5th grade science studies: Is it scientifically correct to say that sunlight which reaches the earth's surface at a low angle (as in during wintertime) is "indirect sunlight"? Sunlight is considered direct if the sun is overhead and the angle of incidence is high (close or at 90 degrees), but is low angel sunlight just less direct as opposed to indirect? I think of indirect sunlight as reflected or dispersed sunlight.

Just wondering why all our huge bodies of water are salt water? if you put salt in a glass of water it eventually all settles to the bottom are the oceans slowly doing this? What happened to cause salt water? when water was formed on earth and most of the planet was water was it salt water then?

Where the organization announced the Commonwealth Scientific and Industrial Research in Australia, CSIRO today announced the first discovery is very surprising, when I discovered that there were nine new species of fish, which are not already on the bottom of the sea!! Know this wonderful fish you see in the picture as "a Pink Handfish", one of the family Handfishs that have been discovered for the first time in 1999 in the Tasman Peninsula, Australia. Strangely, this family is a distinctive fish used their fins to walk on the seabed and the ocean rather than swim, so scientists dubbed the "fish with a hand" to use their fins Koidi going out on the seab…

Was the Middle-East a jungle full of trees and shrubs, like billions of years ago? I ask this because I know that Middle-Eastern countries usually have lots of oil reserves and many of them are major exporters to the rest of the world. I also know that oil is produced from the decomposition of plant material with time/pressure etc. If the Middle-East was a jungle once, what caused it to become a desert now?

I have a lot more information but first any ideas?

If you had a ball of a sticky substance , and u rolled it over the earth , eventually the ball will reduce as it rolls while parts of it are sticking on the earth as it rolls but as every peice sticks , when does the substance stop existing because if u moved the last molecule of stickiness on something else it will keep sticking and so on hard to explain hope u guys figure it out

The sandy soil in the sand dune is dry and porous. I would like to know the air content 1 meter (3.3 ft) below the surface. How much the air is there?

Does anyone know when the world's oil supply will run out? In what year will there be no more oil?

Just wondering what the average day to day wave height is of oceanic waves. lets say in the Atlantic away from the coast in the open ocean. I am looking for the average wave height on calm days with no weather, and the average wave height for stormy days. i found NOAA and their wave height and period forecast over a period of days. It appears that the average height = 4m and the average period = 10 But that is just in an area that didn't change much. the height and period would be greater if i chose an area that had a greater change, ie closer to the shoreline. using those figures i did a quick calculation of the average power of the waves. i came up wit…

Why is the temperature hotter the farther down you go in the earth? Is it because of the gravitational pressure?

I have an attachment with a chart i made about meteorites. The question is the the first 2 red "X"'s at the bottom. Can you give me an estimate as to how old 3 feet down in New Jersey's Salem Counties soil is? I'm not looking to have an exact answer, i just want a ballpark for something i am working on. Second, how long would it take a meteorite to break down in the soil of Salem county in New Jersey? Thanks 1234.pdf

I saw meteorite men and thought about where abouts meteorites fall. Then i decided to figure out how often they fall near me. I just want to know if the math is right? Please correct what is wrong. It is all based on 2 numbers, Earths total square miles and total meteorites per year which are both rounded, so it's not perfect. If you can help i'd appreciate it. P.S. .0005 came from 58,000,000 devided by 29,000. Thanks again The attachment has the chart. Also the 61 years thing i know is wrong, forgot to delete that. meteotie chart.pdf

Greetings, science-types! I'm more of a literary type, specifically science fiction, but I like my fiction to at least have a seed of fact in it. This may be better placed in the chemistry forums as it's about grown crystals, but it's also about physical properties of geological elements, so...I don't know. I'm designing low-tech creatures on a very acidic planet who immerse themselves nightly in order to grow a crystalline crust to protect against acid erosion, and use some kind of file in the morning to sand themselves smooth. This requires a substance with the following properties: 1. Can be grown as a crystal or as an impure mix of crystals in a pool of chemi…

Hello fellow Mycologists! This is my first post (hopefully of many) on scienceforums. I am a mycologist in search of new and hopefully diverse ways to create Agar. Please share your agar recipes!

Japan is getting really uptight because China has stopped sending rare earth to Japan, since Japan arrested the captian of a Chinese fishing boat who rammed Japanese boats. Japan must have rare earth to make things like computers. It might be able to get some rare earth fron Vietman, but this is beside the point. The point is, rare earth is rare and our high tech. industries must have it and I would like to know how to go about finding it. Investing in rare earth would be a good idea for those who have money to invest.

For a glacial study i am undertaking i want to prove a hypothesis that a Ribbon lake once occupied a valley because it was dammed at the end by morraine. For this i will be using an ogre too dig down into the soil on the valley floor. Does anyone no what sort of things i should be looking for in the soil that will prove my Hypothesis. Any info would be greatly appreciated.

According to summitsofcanada, on May 26 1991 Mount Logan recorded a temperature of -77.5 °C, making it the coldest recorded temperature outside Antarctica. But what would the temperature be at the peak if Mount Everest (which is 2889 meters higher than Mount Logan) was located where Mount Logan is?

hello, i need help on my take home oceanography test because i just dont understand anything, all of the following questions are truth or false, so plz help me out here guys, i rly need to pass this test to pass the class. since their initial formation, the ocean basins have stayed relatively unchanged. hydrogen bonds are weak associations between polar molecules such as water density increases with increasing temperatures. abyssal plains are found on the deep ocean floor at depths of up to 5000 meter. most major animal phyla evolved some 500 million years ago the southern hemisphere is composed of over 2/3 landmasses carbon dioxide is limit…

Retrofitting CCS machinery and equipments to old power plants is always going to be clumsy and costly, and uncertain as well. But, are the new power plants going to do much better when it comes to installing CCS systems? Will they be "shovel ready" in that CCS systems could be installed in them far more easily? For instance, this article (see the article Sargas Technology – Carbon Capture Under $20 Per Ton? ) claims that a particular technology from Sargas will work with new pressurised fluidized bed combustion systems much more easily because the technology requires the flue gas to be under pressure to work. Similarly, it is well known that IGCC power plants are far …
