Answer:
Surface mining
Explanation:
The method covered in the question above is called Surface mining.
Surface mining refers to the practice of extracting ores that are in the soil at medium and shallow depths, that is, they are close to the surface. This type of extraction of ores, exploits the mineral deposits until it causes its depletion, creating small depressions in the land that can be used to create landfills. The main ores found in this type of extraction are: limestone, clay, marble, coal, plaster, among others.

At a time 3.5 billion years ago, the primordial atmosphere had a large fraction of carbon dioxide transformed into one that had a larger fraction of free oxygen. Early photosynthesizing organisms cause this to occur.
What types of organisms may photosynthesize?
Both eukaryotic and prokaryotic species possess the capacity for photosynthetic activity. The most famous examples are plants because, with the exception of a very small number of parasitic or mycoheterotrophy species, they all have chlorophyll and can make their own sustenance. The other major class of eukaryotic photosynthetic organisms is the algae.
Bacteria can they photosynthesize?
Some bacteria participate in photosynthesis, including cyanobacteria and purple and green sulphur bacteria. Bacteria don't have chloroplasts; thus, their membrane folds are where you can find photosynthetic pigments.

Can bacteria photosynthesize?Cyanobacteria and purple and green sulphur bacteria are two types of bacteria that take part in photosynthesis. Since bacteria lack chloroplasts, photosynthetic pigments are found in the folds of their membranes. A process known as photosynthesis enables some bacteria to transform solar energy into a different kind of energy that can be used for growth.

Electromagnetic waves of various frequencies reach earth from distant parts of the universe. What conclusion can be drawn from this statement?.
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.

what is a dangerous hot ash and gases cloud that rolls down the side of a volcano, such as mt. pelee in martinique, during an explosive volcanic eruption?
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.

Why did Wegener use fossils to support his continental drift theory?
Their fossils have been found across South America, Africa, India, and Antarctica. Wegener thought that all of these organisms must have lived side by side. The lands later moved apart so that the fossils are separated. Wegener used fossil evidence to support his continental drift hypothesis.
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. A pioneer of the modern-day view of mobilism turned into the Austrian geologist Otto Ampferer. The concept changed independently and extra completely developed by Alfred Wegener in 1912, but the speculation changed into rejected by using many for loss of any cause mechanism.

The locus of all locations such that the sum of the distances to two fixed points (the foci) is constant is known as an ellipse. Therefore, by definition, there must be two foci to satisfy this condition.
The eccentricity of the ellipse increases with the distance between the foci. The figure is actually a circle when the foci are stacked on top of one another/

1. Wet granite melts and produces magma at a depth of 25 km, as indicated by the intersection of the wet granite curve and the geothermal gradient.
2. As we can see from the graph of basalt, basalt will melt above the point where it crosses the geothermal gradient curve at 1400 °C, a depth of more than 100 kilometres. It won't be moulted because they ask for more deep basalt than 100 km. Hence There hasn't been a rise in the melting temperature. Basalt should be solid below 100.

What will happen if the Earth emits more heat radiation than it receives from the Sun?
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.

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.
