Answer:
The correct answer is d) atmospheric air pressure
.
Explanation:
The atmospheric pressure, also known as barometric, is what causes the weight of the mass of air that is acting on the earth.
This value will be higher or lower, depending on the altitude at which we are, with reference to the lowest point considered, which is usually the sea level, but is also influenced by some atmospheric effects produced by the circulation of currents of warm or cold air.
Theoretically, it is considered that the maximum value of atmospheric pressure is achieved at sea level, although in some parts of the earth there are areas below that level. Its value at this point corresponds to 1013 mbar or 760 mm Hg. The value of 1 atmosphere (atm) is also commonly used as a reference unit, but is not included in the International System of Units.
It is also known as barometric pressure, due to the instrument used for its measurement. It was Evangelista Torricelli who in 1643 invented the first barometer, although the name was given by Edme Mariotte some years later.
Answer:
Deep ocean exploration is all about investigating its geology i.e physical and chemical along with biological conditions on the ocean floor where sunlight cannot reach. There has been an interest in the deep ocean due to scientific communities and for industrial purpose. Exploration is carried by submarine and remotely operated vehicles at about 300m to 1000m. Analysis of ocean floor had found a huge concentration of mineral deposits such as manganese, copper, cobalt, gold, zinc etc.
The mining is carried out by using hydraulic pumping or bucket type excavator and are processed on ground industries. Deep-ocean mining has not been able to reach its full potential due to the high cost of operating and environmental damage.
Answer:
True
Explanation:
The Cordilleras have one major factor that distinguishes them from the other mountain ranges, the three phases of its orogeny. Unlike most of the mountains in the world that have been created by a single orogenic process, that is not the case with the Cordilleras. There have been three consecutive orogenies, the Nevadan, Sevier, and Laramide orogenic process that created the Cordilleras, thus making them a unique mountain range.
Answer:
The answer is below.
Explanation:
Constructive is when two plates are being pulled by convection currents.
Destructive is when an oceanic plate is destroyed by the thicker continental plate.
A collision is when two continental plates push against each other and buckle.
Conservative is when two plates slide past each other along a fault line.
Seven countries make up the region of Central America, two of them are Belize and Costa Rica.
