To begin with, there are two ways to extract crude bitumen and turn it into a usable product: open-pit mining and in situ (in place) 5. However, the technique used largely depends on the depth of the deposit 5. Therefore, on the one hand, oil sands will be surface mined and sent to a bitumen processing plant if the deposit is close to the ...

The Composition and Structure of Earth. Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth's mass. Finally, the core is mostly iron metal.

The strength of the earth's magnetic field is about is 10-4 T or (1G). We can draw magnetic lines of force of earth's magnetic field on a sheet of paper without placing any magnetic substance in the vicinity. A series of parallel straight lines are obtained directed approximately from geographical south or north.
The spectral line also can tell us about any magnetic field of the star. The width of the line can tell us how fast the material is moving. We can learn about winds in stars from this. If the lines shift back and forth we can learn that the star may be orbiting another star. We can estimate the mass and size of the star from this.
The gravity of Earth, denoted by g, is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).. In SI units this acceleration is measured in metres per second squared (in symbols, m/s 2 or m·s −2) or equivalently in newtons per kilogram (N/kg or N·kg −1).
The ecliptic is the path the sun, moon, and planets take across the sky as seen from Earth. It defines the plane of the Earth's orbit around the …
Evolution and the timeline of life on earth happened in stages over 4.6 billion years. From cyanobacteria to fungi. Dinosaurs and chickens. Whales and cows. Monkeys to humans, the evolution of life is a story with surprising twists. Earth has been home to …
Earth's magnetic field gets stretched out into a comet-like shape with a tail of magnetism that stretches millions of miles behind the earth, opposite from the sun. The sun has a wind of gas that pushes the earths field from the left to the right in the picture. Scientists have studied many different parts of the Earths magnetic field and have ...
Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. Surface Mining If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
The orbit of the Earth is elliptical or oval in shape, or like a stretched circle, with the Sun roughly at the center of the orbit. At different times of the year, the Earth either moves closer or farther away from the Sun. At perihelion, the Earth's closest distance to the Sun, the distance between the Sun and the Earth is 91.4 million miles.
Albert Einstein's 1905 theory of special relativity is one of the most important papers ever published in the field of physics. Special relativity is an explanation of …
This gallery includes all Landsat images published on the Earth Observatory, Visible Earth, and Landsat Science web sites from all seven Landsat satellites (Landsats 1-8, Landsat 6 failed to achieve orbit). All of the images are in the public domain and may be used with attribution. The correct attribution for imagery obtained from this site is:

I use Google Earth Pro (7.1) on a daily basis to assess the acreage of US agricultural fields using the GE ruler. What is the accuracy we can expect from Google Earth Pro for surface calculation? (the fields don't always have simple shapes and are sometimes in remote areas) …
where y = the quantity plotted on the y-axis (velocity), x = the quantity plotted on the x-axis (distance), and m is the slope of the line. For the specific case of this relationship, we usually write the equation this way: v = H 0 d. H 0 is called the Hubble constant. It is the slope of the line …
Earth is farthest from the sun, or at "aphelion," in July when it's about 95 million miles away. At the equator, Earth spins at just over 1,000 miles per hour. Earth makes a full spin around its axis once every 24 hours, or one day. The axis is an imaginary line through the center of the planet from the North Pole to the South Pole.
Gasoline is a volatile, flammable liquid obtained from the refinement of petroleum, or crude oil. It was originally discarded as a byproduct of kerosene production, but its ability to vaporize at low temperatures made it a useful fuel for many machines.
The point of application of the active earth pressure is also obtained. The calculated values agree well with those from physical tests in the previous literature. Furthermore, the effects of the width of the backfill, internal friction angle of soil, and wall-soil friction angle on the distribution of active earth pressure are discussed.
The Karman Line is an imaginary boundary that lies 100 kilometers above Earth and is widely considered the boundary between the outer space and Earth's atmosphere. The line owes its name to Theodore von Karman – a Hungarian American physicist who was the first to determine that around this altitude, the atmosphere became too thin to support ...

Aerial and satellite images, known as remotely sensed images, permit accurate mapping of land cover and make landscape features understandable on regional, continental, and even global scales. Transient phenomena, such as seasonal vegetation vigor and contaminant discharges, can be studied by comparing images acquired at different times.
Microbial life forms have been discovered on Earth that can survive and even thrive at extremes of high and low temperature and pressure, and in conditions of acidity, salinity, alkalinity, and concentrations of heavy metals that would have been regarded as lethal just a few years ago. These discoveries include the wide diversity of life near sea–floor hydrothermal vent systems, where some ...
Tons of resources extracted from Earth. The 2008 OECD Environmental Outlook to 2030, p240 estimates 81.4 billion tons in 2020. We use the more recent 2017 UN estimate of 88.6 billion tons. From 1970 to 2010, the annual global extraction of materials grew from 26.7 billion tonnes to …
Therefore, time zones in the world are obtained from the UTC. An area on earth can either be ahead (+) or behind (-) the UTC, which means that UTC is 0 hours. Given that there are 24 hours in a day, it is logical to state that the biggest time difference between two points on earth …
If there were no gravity the ISS would move away from the Earth in a straight line along a tangent to its present orbit. Gravity accelerates the ISS towards the Earth continuously, meaning it's constantly falling towards the planet but "missing", because the Earth curves out of the way.

Earth's rotation or Earth's spin is the rotation of planet Earth around its own axis, as well as changes in the orientation of the rotation axis in space. Earth rotates eastward, in prograde motion.As viewed from the north pole star Polaris, Earth turns counterclockwise.. The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere ...
R is the radius of the Earth. Let me make one assumption -- that the arc length in the diagram (like s 1) is essentially the same length as the straight-line distance (x 1). Clearly, this is not ...
Helium is mined along with natural gas, using a drill rig to drill wells deep into the earth's crust. A drill rig must penetrate a layer called the Cap Rock to reach a natural gas reserve. Once located, the natural gas and Helium rise and fill the rig, which are then led through a series of piping systems that transport the natural gas and ...
A domain earth over cube is provided, which includes constraint checks that the value meets these restrictions and is reasonably close to the actual surface of the Earth. The radius of the Earth is obtained from the earth() function. It is given in meters.
Hello Plex.Earth users, here we are covering the subject of how to create a surface when you have already obtained contours from other sources (e.g survey). Often, designers are given this information, which, based on a local survey, can be more accurate than the ones available from Google Earth and which can be obtained using Plex.Earth.
