The reason that olympus mons, the tallest mountain on mars, is taller than mount everest (the tallest mountain on earth) is that:_____.
The reason that olympus mons, the tallest volcano on mars, is taller than mount everest (the tallest mountain on earth) is because of Mars' low gravity, slow-moving tectonic plates, and high volcanic activity.
Olympus mons is a shield volcano in the western hemisphere of Mars. At 72,000 feet high (2.5 times the height of Mount Everest) and 374 miles wide (roughly the size of Arizona), it is the largest volcano in the solar system. Mars' atmosphere is so thin that volcanic peaks actually protrude above it. Shield volcanoes, like Olympus Mons, form when lava slowly flows out of the ground and spreads out, creating a low, squat appearance. Shield volcanoes have an average slope of only 5%, and therefore the height of Olympus Mons is even more impressive.

If a flat lying sedimentary rock layer ends abruptly, which principle tells that it has likely been deformed
The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.
What are the stratigraphic principles?Superposition principle
Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.
According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.
Lateral continuity principle
When talking about lateral continuity, we refer to different strata -sedimental layers- horizontally deposited that have a limited continuity.
This is, when looking laterally, each layer is not infinite. They tend to smoothly end.
These layers get thinner as they get farther from the source until they disappear.
When looking at plane rocky strata, we can notice they have not suffered from any perturbation and keep the original horizontality.
As they disappear, they tend to
• Mint
• Harrow
• Interdigitate
• be truncated
Original horizontality principle
This principle refers to the fact that strata extend originally in all horizontal directions. Sedimental layers are horizontally deposited.
However, it may occur that the currently observed strata arrangement is not the same as it used to be.
This is due to tectonic changes that have modified the original positions. Thus, layers can appear
folded, slanted, or inverted⇒ leaving the most ancient layers in the upper positions.The principle that tells that the flat lying sedimentary rock layer, which ends abruptly, has likely been deformed is Original horizontality principle. Option D.

The moment magnitude is based on the ___________ and ___________ of the earthquake.
The moment magnitude is based on the amplitude and displacement of the earthquake.
An earthquake's magnitude can be determined in a variety of ways. The amplitude of seismic waves measured by seismometers serves as the basis for the majority of scales. Since these scales take into consideration the distance between the earthquake and the seismometer used to record it, the computed magnitude should be roughly the same everywhere it is observed. A different scale is based on the size of the earthquake fault physically and the quantity of slip that took place. Intensity measurements for earthquake shaking are also available. From one earthquake's epicenter to another, its intensity varies substantially.
Because it can be used globally and covers a greater range of earthquake sizes, the moment magnitude scale, abbreviated MW, is recommended nowadays. On the total moment release of the earthquake, the moment magnitude scale is based. Moment is a function of the fault's movement's distance and the force needed to move it. It is produced from earthquake recordings made at various places using modelling. For mild to big earthquakes, Richter magnitudes and moment magnitude estimations are similar.

Is wood a renewable or non-renewable resource?
Answer:
Renewable
Explanation:
Renewable resources include biomass energy (such as wood, sewage, and ethanol), hydropower, geothermal power, wind energy, and solar energy.
Answer:
wood is a renewable resource
Explanation:
because we are able to replace wood (to make more of it), it is considered renewable.
(it does not run out--it can be replaced)
"non-renewable" resources are essentially limited resources--such as oil. There is a limited amount of oil--we are able to run out of it. There is no (current) way for us to reproduce oil, which is why it is different from wood (a renewable resource).

Answer:
between 7 and 11 centimeters (cm) or ~3-4 inches a year.
Explanation:
the content of carbon di oxide in the atmosphere keeps on fluctuating. Explain
Answer:
Plants play a large factor in fluctuating levels of CO2 within the atmosphere. Plants, through photosynthesis, convert CO2 gas into sugars and O2 gas powered through sunlight. In different seasons, the plants become active or deactivate and can undergo different amounts of photosynthesis. For example, during the winter, CO2 is very high, as many plants are not undergoing photosynthesis and cannot convert the CO2 into O2. But in spring, CO2 is drastically lowered as they are far more active in converting the atmospheric gas.

Water harvesting: Since the soil was eroded, they first set up water harvesting structures, such as swales, trenches, percolation tanks. These systems increased the efficiency of water use, recharged four existing borewells (which were not effective) and ensured a regular supply without taking from the reservoir.
Sapling plantation: Water harvesting is incomplete without planting. Saplings from government and private nurseries were used in the first plantation cycles. A nursery was set up to host young trees and plants which were later planted at Polam. The goal was to revive soils and life by planting diverse species.
Fencing: In an arid region, fires are common. To avoid damage, live fences were raised around the boundaries, and windbreaks such as huge teak trees were planted to brave the South wind blowing from the reservoir. Fruit trees have now fully reforested another 2 hectares acre of the farm. The fruit forest has become a new habitat for insects, animals and birds.
Regenerate through biodiversity: In the rest of the land, trees and plants have been scattered between local species, which adapt to the dry land climate, and tropical species. Although some died, diversification ensures that there is regeneration of life.
