Interpreting Prospecting Ore Test Result

Asked by: Dave Day What is a high grade nickel deposit? Therefore, anything over 20 metres in thickness (significantly less thickness than other commodities) and 2% nickel grade or better would be reasonably considered high-grade. What is grade of an ore? The grade of ore refers to the concentration of the desired material it contains.

Why were no interferometers launched on weather satellites between the ’69-’72 IRIS-D and the 2002-onward AIRS?

Asked by: Laura Blackburn What is the purpose of a weather satellite? Weather Satellites are an important observational tool for all scales of NWS forecasting operations. Satellite data, having a global view, complements land-based systems such as radiosondes, weather radars, and surface observing systems. There are two types of weather satellites: polar orbiting and geostationary.

Will Lithium batteries mean we have to exploit Co-Mn-Ni nodules from the seafloor?

Asked by: Laura Blackburn Can lithium be mined from the ocean? Researchers have devised numerous filters and membranes to try to selectively extract lithium from seawater. But those efforts rely on evaporating away much of the water to concentrate the lithium, which requires extensive land use and time. To date such efforts have not proved

If the earth were completely smooth and covered in water, what would occur with ocean waves?

Asked by: Cheryl Sine How deep would the ocean be if the Earth was smooth? If the earth were smooth, all the land areas would be covered by seawater to a depth of some 8,810 feet – or one and two-thirds miles. “Sea level” of earth’s oceans varies in elevation by as much as 600

Reisdual soil and the atmosphere influence

Asked by: Cheryl Sine What does residual soil affect most? Residual soils are products of chemical weathering and thus their characteristics are dependent upon environmental factors of climate, parent material, topography and drainage, and age.1 янв. 1985 What two factors are most important in the development of residual soil? Despite this importance, there has been

What is the source of lava of volcano? From magma below crust? Or from molten crust by rubbing?

Asked by: Tony Vadlapatla Magma is directly supplied from magma below crust, in subduction zone the crust rubs and some cracks formed, magma rushes out from mantle and then to the surface of Earth via cracks. The magma is formed by molten crust cause by rubbing and then heating, then it rushes out via cracks.
