The loess deposits in Europe and North America are thought to be derived mainly from _____

Answers

Loess is assumed to have primarily glacial and periglacial origins in Europe and North America.

Where does loess come from?

Loess is created primarily by wind and is also formed by glaciers. Glaciers can turn rocks into a fine powder, which can lead to the development of loess. Streams carry the glacier's terminus's powder. This sediment is converted into loess.

Loess was formed in North America from both glacial and nonglacial causes, but it is often connected to the floodplains of large, braided rivers and to the outwash deposits of the Laurentide ice sheet; parts of the Mississippi River basin may have loess up to a depth of 20 meters.

Why is loess essential and how does it form?

The majority of loess is made up of coarse silt-sized quartz particles with a diameter of 20–63 m, however certain desert loess deposits can contain fine sands with an 80 m or less diameter. Loess is made up of large amounts of wind-blown dust that have been captured, laid down, and preserved on specific terrain.

When tornadoes are sighted or detected by radar, a Tornado Warning—a higher-level alert than a Tornado Watch—is issued. It denotes a significant danger to people, property, and critical infrastructure in the watch area.

During the VORTEX study, theories about how the storm environment controls or modifies tornadic storm structure and evolution were put to the test.

The upper layers absorb intense ultraviolet radiation from the sun. The stratosphere, which starts between 6 and 10 miles above the earth's surface and rises to a height of roughly 30 miles, is where ozone is located.

The "good ozone" that is found in the stratosphere absorbs the majority of the dangerous UV sunlight.The troposphere, the lower part of the atmosphere, also contains ozone. However, the ozone in this area significantly reacts with chemicals that make plants poisonous.

As a result, the ozone is referred to as "bad ozone."When two oxygen atoms in a molecule are broken by powerful photons from the sun, such as UV rays, ozone is produced. The radical atom then joins forces with a second oxygen molecule to form the ozone complex. The same intense photons that form ozone also destroy it at a pace that balances its creation.

Answers

The Himalayas have experienced extreme uplift because continental masses are too buoyant to subduct.​ True.

The Himalayas are a mountain range stretching across South Asia and is home to the highest peaks including Mount Everest. The Himalayas were formed due to a collision between the Indian Plate and the Eurasian Plate. The process of mountain building that occurred during the collision of these two plates is known as orogeny. In the case of the Himalayas, the collision caused the Indian Plate to be thrust upwards and over the Eurasian Plate, resulting in the extreme uplift of the mountain range.

One of the factors contributing to the extreme uplift of the Himalayas is the buoyancy of the continental masses. Continental masses are made up of lighter, less dense rocks, and are less likely to subduct other tectonic plates. When the Indian Plate collided with the Eurasian Plate, the buoyancy of the continental masses on the Indian Plate prevented it from sinking, and instead caused it to be thrust upwards and over the Eurasian Plate.

which fault is older stohr fault or gem fault

Answers

Answer:

gem fault is older than stohr fault

Explanation:

Stohr fault is older than Gem fault. A fault refers to a fracture or a zone of fractures that occurs between two blocks of rock. Option A is the correct answer.

The principle of cross-cutting relationships states that a feature (such as a fault) is younger than the rock it cuts across. If we apply this principle to the Stohr Fault and the Gem Fault, we would need to analyze the relationship between the faults and the rocks they intersect. Option A is the correct answer.

If the Stohr Fault cuts across the rocks that are affected by the Gem Fault, then the Stohr Fault would be younger. This is because the Stohr Fault must have formed after the rocks were already affected by the Gem Fault. In this case, the Gem Fault would be older. On the other hand, if the Gem Fault cuts across the rocks affected by the Stohr Fault, then the Gem Fault would be younger, as it must have formed after the rocks were already affected by the Stohr Fault.

Ne  : Number of star in the galaxy 2 x 10^{11}.

fp:  Fraction of stars with the planet (0.1).

nHz: Number of planets per star which lie in habitable zone for even longer than 4 billion years (0.01).

fL: Fraction of suitable planets for which life begins (0.01).

f1: Fraction of planets within life in which life evolves to intelligence (0.01).

fs:  Fraction of star's existence during a technological society survives 10^{-8}.

Ne = 2 x10^{11}(0.1)(0.01)(0.01)(0.01)x(10^{-8})

Ne =2x 10^{-4}

Thus, the number of communicative civilizations per galaxy is found as 2x 10^{-4}.
