After returning from his journey west, stephen h. long perpetuated the myth that the region between the missouri river and the rocky mountains was ______.

Answers

Answer 1

After returning from his journey west, stephen h. long perpetuated the myth that the region between the missouri river and the rocky mountains was unfit for cultivation.

Stephen Harriman Long (1784–1864) was an American military explorer best known for leading the 1820 expedition to what is now Colorado. On his journey map, he eminently called the arid Great Plains the "Great American Desert".

Even as late as 1823, Major Long of the Army Engineers noted that much of the land between the Missouri River and the Rocky Mountains was "almost wholly unfit for cultivation, and of course uninhabitable by a people depending on agriculture for their subsistence."

Today, the adaptation of technology to semi-arid areas and the development of new technologies have made the Great Plains one of the most productive agricultural regions in the world.

Updrafts dominate the cumulonimbus cloud during the ________ in the life cycle of an air mass thunderstorm.

Answers

Updrafts dominate the cumulonimbus cloud during the cumulus stage in the life cycle of an air mass thunderstorm.

Although first cumulus clouds frequently perish, their deaths are not in vain. In the same column as the initial cumulus, new cumulus clouds frequently form, benefiting from the water vapor from earlier-evaporating cloud particles.

Even if entrainment into the newly forming cumulus still continues, the air that is mixing into the cloud is more humid than before, which, as you may remember, reduces the possibility of net evaporation (and evaporational cooling).

A series of cumulus clouds can now develop and dissipate in a single column of air if there is an adequate supply of low-level moisture and persistent positively buoyant parcels throughout time.

Fair-weather cumulus eventually gives way to cumulus congestus, which is a towering cloud.

What is the Ocean current?

Generally, Any flow of water in the ocean that goes in the same direction as the ocean current is considered to be part of the ocean current.

Ocean currents play a significant part in the regulation of the climate by transporting heat away from the equator and toward the poles. Ocean currents are another factor that is of vital significance to marine life. They transport nutrients and food to creatures that dwell permanently connected to one area. Additionally, they transport reproductive cells and ocean life to new locations.

In conclusion, Ocean currents are the continuous movements of seawater in one direction that are caused by gravity, wind (the Coriolis Effect), and the density of the water. The water in the ocean may be seen moving in both a horizontal and a vertical direction. Currents are the term used to describe horizontal movements, whereas upwellings and downwellings are terms used to describe vertical changes.

If a mid-latitude cyclonic storm has moved from the southwest toward the northeast during the past six hours, the storm is likely to move toward the ____ during the next six hours.

Answers

If a mid-latitude cyclonic storm has moved from the southwest toward the northeast during the past six hours, the storm is likely to move toward the northeast during the next six hours.

What is a cyclonic storm?

A storm or system of winds that rush forward at a speed of 20 to 30 miles per hour (30 to 50 kilometers per hour), revolves around a center of low atmospheric pressure, and frequently produces heavy rain.

The precise word for this region of low pressure where the water spins about is the eye. These storms have an eye in the middle, and the outlying parts of the spinning storm produce a ton of wind and rain. Cyclones are brought on by the continuous ascent of hot air and the filling of the void by nearby cool air.

Answers

The contribution margin is first used to cover fixed expenses. Once the break-even point has been reached, the contribution margin becomes profit.

What Is Contribution Margin?

The contribution margin may be expressed as a gross or per-unit figure. After the variable element of the company's costs are subtracted, it indicates the additional revenue made for each product or unit sold.

The selling price per unit less the variable cost per unit is used to calculate the contribution margin. The measurement, also known as dollar contribution per unit, shows how a specific product affects the company's overall profit.

How is Contribution Margin Calculated?

The difference between a product's sale price and the variable costs related to its manufacturing and selling process is calculated as the contribution margin.

Revenue minus Variable Costs equal contribution margin. The contribution margin ratio is computed as (Revenue - Variable Costs) / Revenue.

What Constitutes a Good Contribution Margin?

The closer the contribution margin is to 100%, the better, as 100% is the ideal contribution margin. The greater the number, the better a corporation is at covering its operating expenses with cash on hand.

the content of carbon di oxide in the atmosphere keeps on fluctuating. Explain​

Answers

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.

What prevents each spot on earth from experiencing two high tides and two low tides a day?

Answers

Because of the moon's gravitational pull on the Earth and the Earth's rotational force, coastal areas experience two high and two low tides.

Tides are the alternating movement of water along the coast. High tide is when water advances to its farthest extent onto the oceanfront. Low tide is when it recedes to its farthest extent. The side of the Earth closest to the Moon experiences the Moon's strongest gravitational pull, causing sea levels to rise and tides to occur. On the far side of the Moon, the Earth's rotational force is stronger than the Moon's gravitational pull. The sun's gravitational pull also plays a minor role in the formation of tides. Tides move around the earth as bulges in the ocean.

What is Geography and Climate?

The study of the Earth's natural physical features and human interactions with those features is called geography.

While the study of the Earth's atmosphere and long-term weather patterns over a particular region is called climatology.  Climate is studied over a broad range of spatial and temporal scales.

For example, scientists may focus on the climate of a city, a geographic region, a continent, a hemisphere, or the planet as a whole. Climate is also studied on time scales ranging from as short as a few decades to scales spanning millions of years.

Geography and climate are connected in several ways. For example, the topography and nature of the materials that make up the ground surface (e.g., type of vegetation, sand, water, asphalt, etc.) The distribution of heat at the ground surface determines ambient temperatures and the rate of water transfer from surface regions to the atmosphere through evaporation, a key process in determining a region's climate.
