Answer:

Soils normally form from  sediments transported by wind, water, and ice

Explanation:

The soil is dependent on the minerals of soil. They are formed by weathering mechanisms and natural erosion from rocks (source material). Water, air, difference in temperatures, gravity, chemical reaction, living organisms and differences in pressure all help break parent material.

Soils formed from the rocks. When rain water is accumulated in capillaries (narrow holes), in a number of parts they break down the rock. Thus get way to form soil minerals which on accumulation result in soil

BlackZzzverrR [31]

Answer:

\large \boxed{\text{1.76 m}}

Explanation:

Data:

Lifetime = 2.55 × 10⁻⁸ s

 Speed = 0.230c

Calculations:

\text{Speed} = \text{0.230c} = 0.230 \times \dfrac{\text{2.998 $\times 10^{8}$ m}}{\text{1 s}} = 6.895 \times 10^{7}\text{ m/s }\\\\\begin{array}{rcl}\text{Distance} & = & \text{speed $\times$ time}\\& = & \dfrac{6.895 \times 10^{7}\text { m}}{\text{1 s}} \times 2.55 \times 10^{-8}\text{ s}\\\\& = & \textbf{1.76 m}\\\end{array}\\\text{The pion travels $\large \boxed{\textbf{1.76 m}}$ in its lifetime.}

1. How were the continents during suilurien

Ans: During the Silurian , the Earth witnessed many changes in the way in which landmasses were distributed around the globe. Although there were no major volcanic events, a deglaciation and rise in sea levels occurring at that time produced varying periods of continent coverage and exposure. The variation of ocean levels occurred alongside the process of continental fragmentation and grouping that occurred from the Cambrian to the present.

At that time, the continents were distributed very differently than they are today. The Silurian world consisted of a vast north polar ocean and a south polar supercontinent (Gondwana) with a ring of approximately six continents. By the Silurian period, a large portion of the Rodinian landmass had become fragmented, and those fragments migrated toward the equatorial region. Most of these fragments were eventually assembled by a series of plate collisions into the super-continents of Laurussia and Laurasia. The modern Philippine islands were most likely inside the Arctic Circle, while Australia and Scandinavia resided in the tropics; South America and Africa were probably over the South Pole.

There was no major volcanic activity during the Silurian; however, the period is marked by major orogenic (mountain-building) events in eastern North America and in northwestern Europe, resulting in the formation of the mountain chains there. This was called the Caledonian Orogeny. In other areas, large igneous rock formations of the Middle Silurian arose, such as those in Central Europe, as well as light sedimentation throughout the Baltic region. While not characterized by dramatic tectonic activity, the Silurian world experienced gradual continental changes that would be the basis for greater global consequences in the future, such as those that created terrestrial ecosystems.

The Silurian oceans are also of particular interest for activity between the regions known as Laurentia, Baltica and Avalonia. The ocean basins between these areas substantially closed together, continuing a geologic trend that had begun much earlier. The new marine habitats produced by these profound changes in the Silurian seas provided the framework for significant biological events in the evolution of life. Coral reefs, for example, made their first appearances in the fossil record during this time.

The Silurian period was a time when the earth underwent considerable changes that had important repercussions for the environment and the life within it. The Silurian witnessed a relative stabilization of the world's general climate, ending the previous pattern of erratic climatic fluctuations. One significant feature of these changes was the melting of large glacial formations. This contributed to a substantial and significant rise in the levels of the major seas, creating many new marine habitats.

The Silurian period's condition of low continental elevations with a high global stand in sea level can be strongly distinguished from the present-day environment. This is a result of the flood of 65% of the shallow seas in North America during the Llandovery and Wenlock times. The shallow seas ranged from tropical to subtropical in climate. Commonly present in the shallow seas were coral mound reefs with associated carbonate sediments. Due to reduced circulation during the Ludlow and Pridoli times, the process of deposition of evaporites (salts) was set in motion. Some of these deposits are still found in northern Europe, Siberia, South China and Australia.

A company borrows $21,000 to purchase a new piece of equipment. The loan will be repaid in one lump sum at the end of 8 years. T
Alisiya [41]

Answer:

$509

Explanation:

First, we find the lump sum to pay under the bank terms. The interest rate is 0.5% monthly, which is equivalent to 6.2% annually.

The formula is:

P (1 + i)^{n} = X

Where:

  • P = Present value
  • i = interest rate
  • n = number of compounding periods of the interest rate
  • X = lump sum we need to find

Now, we simply plug the amounts into the formula:

$21,000 (1 + 0.062)^{8} = X\\

33,979 = X

Next, we find the value of the lump sum under the company's preferred terms:

21,000 (1 + 0.06)^{8} = X

33,470 = X

Finally, we susbtract the two figures to find the difference:

39,979 - 33,470 = 509

Analyze the map below and answer the question that follows. A satellite map of South Asia. An area northeast of India with Nepal
Lelu [443]

Answer:

The correct answer is D, the Himalayan Mountains.

Explanation:

The Himalayas is a high mountain system in Asia. It is the highest mountain range on Earth and lies between the Indian subcontinent in the south and the Tibetan highlands in the north. The mountains stretch for a length of about 3000 kilometers from Pakistan to Burma and reach a width of up to 350 kilometers. In the Himalayas are ten of the fourteen highest mountains on earth, the peaks of which are more than 8000 meters high, including Mount Everest, which is 8848 m above sea level being the highest mountain on Earth. With its southern location and the Tibetan highlands rising up in the back of the Himalayas as an extensive high plateau, the Himalayas have a great influence on the climate of South and Southeast Asia.
