Method to mine a mineral deposit which includes open pit mining quarrying placer mining and strip mining

A dangerous hot ash and gases cloud that rolls down the side of a volcano during an explosive eruption is known as a pyroclastic flow.

Pyroclastic flows are composed of a hot mix of ash, volcanic rock fragments, and toxic gases, and they move very quickly down the side of a volcano at speeds of up to 100 mph. These flows can be incredibly destructive and can cause large-scale destruction over a wide area, including the complete obliteration of entire towns and villages.

The pyroclastic flow that occurred during the 1902 eruption of Mount Pelee in Martinique is a prime example of the destructive power of these flows. The eruption itself was preceded by a powerful earthquake, which caused the volcano to explode, sending a massive plume of ash and smoke high into the air. As the eruption continued, a pyroclastic flow cascaded down the side of the volcano at speeds of up to 100 mph. This pyroclastic flow incinerated the nearby town of St. Pierre in about three minutes, killing some 30,000 people in the process.

In addition to the sheer speed at which they travel, pyroclastic flows are incredibly hot, reaching temperatures of up to 1,830 degrees Fahrenheit. This heat is more than enough to cause severe burns, destroy buildings, and char trees and vegetation. Pyroclastic flows can also cause landslides and mudflows, which can further contribute to the destruction.

The conclusion that can be made from this statement is that electromagnetic waves do not require any medium to travel.

Electromagnetic waves are waves composed of an electric field and a magnetic field. In these waves, the electric field and the magnetic field oscillate perpendicular to each other and the direction of the net flow of energy is determined by a pointing vector which says that the direction of the net flow of energy is in direction of the cross product of the magnetic field vector and electric field vector.

Electromagnetic waves are a special type of waves that do not require any medium to travel and can travel in space as space is majorly vacuum.

Therefore due to this property electromagnetic waves of various frequencies reach earth from distant parts of the universe.

Continental go with the flow is the hypothesis that the Earth's continents have moved over geologic time relative to each other, as a result acting to have "drifted" across the sea bed. The idea of continental go with the flow has been subsumed into the science of plate tectonics, which researches the movement of the continents as they experience on plates of the Earth's lithosphere.

The speculation that continents might have 'drifted' was first put forward by way of Abraham Ortelius in 1596.

Beach size varies with each storm, but on average over a few decades, a normal sandy beach's size is typically regulated by the equilibrium between sand supply from rivers or coastal erosion and sand loss to the deep sea. The right response in this case is option D.

The majority of beach materials are the result of erosive weathering. Water and wind erode the ground over a long period of time. For instance, certain rocks may break free as a result of the constant motion of waves crashing against a rocky bluff. Massive boulders can be reduced to the size of sand grains.

A rocky beach is produced when large waves carry sand offshore and onto longshore sand bars. A broad, sandy beach is produced when little waves push sand up the beach face.

Sand is created as rocks erode and weather over decades, even millions, of years. The decomposition of rocks, particularly quartz (silica) and feldspar require time. Rocks slowly move down rivers and streams, often beginning thousands of kilometers from the ocean, continually disintegrating along the way.

Complete question:

Beaches change size with every storm, but if you average over a few decades, the size of a typical sandy beach is usually controlled by: a group of answer choices

A - the balance between the removal of sand

B - the beach by smaller summertime waves, and gain of sand from deep water by bigger wintertime waves.

Answer:

If the temperature of the apparent surface is too high and Earth radiates more heat than it receives, the planet will become colder and radiate less energy back to space.

Explanation:

The "greenhouse effect" is widely discussed in the media, and although its details are complicated, its principles are not difficult to understand. Without a greenhouse effect, radiation from the Sun (mostly in the form of visible light) would travel to Earth and be changed into heat, only to be lost to space. This scenario can be sketched as follows:

Sun's radiation → absorbed by Earth → Re-radiated to space as heat

The greenhouse effect is a phenomenon in which solar energy quickly enters the lower atmosphere and the surface of the Earth, transforms into heat, but cannot thereafter leave the globe freely. Here is a rough sketch of this:

Earth absorbs solar radiation, some of which is then retained by the atmosphere or re-radiated into space as heat.
