How would the Coriolis effect alter movement of an air mass flowing from a higher to a lower latitude in the Southern Hemisphere? It would deflect the path of the air mass to the east. It would deflect the path of the air mass to the west. It would deflect the path of the air mass to a lower altitude. It would deflect the path of the air mass to a higher altitude.

Answers

Answer:

It would deflect the path of the air mass to the west.

Explanation:

The Coriolis effect would deflect the path of the air mass to the east. Thus, option 'A' is the correct option.

What is the Coriolis effect?

The deflection of winds on Earth is one of the most frequent instances of the Coriolis effect in operation. We perceive the Coriolis force, an apparent force caused by the rotation of the Earth. In the northern hemisphere, this causes the wind to be deflected to the right, and in the southern hemisphere, to the left. This explains why the wind flows in each hemisphere in the opposite direction around low and high-pressure systems.

Gustave-Gaspard de Coriolis, a French scientist and mathematician in the 19th century, first described the Coriolis effect in 1835. He developed fluid dynamics theories after researching waterwheels and came to the conclusion that the same theories could be used to explain fluid motion on the Earth's surface.

7. Describe the difference between a command, a market, and a mixed economy. (3 points)

Answers

Hey there! I'm happy to help!

-------------------------------------------------------------------------------

COMMAND ECONOMY

A command economy is an economy that is controlled by the government or the state. The government dictates what will be produced, how much of it will be produced, and the method by which it will be produced.

This is the type of economy found in socialist and communist countries, where the government has much more power to plan the economy to improve it for the citizens of the country. The means of production are collectively owned.

This economy can be found in countries such as China, Vietnam, Cuba, Venezuela, and Laos.

-------------------------------------------------------------------------------

MARKET ECONOMY

A market economy is one that is controlled by the customers and businesses. As a consumer, you vote with your dollars. If nobody buys a product that a company makes, the company will stop making that product. The companies individually decide what they will produce, how they will produce it, and how much of that thing they will produce.

This is the type of economy usually found in countries with a smaller government, where the government has less control of the economy and it is controlled by the people, companies, entrepreneurs, etc.

This economy can be found in countries such as the United Kingdom, Australia, Singapore, Canada, etc.

-------------------------------------------------------------------------------

MIXED ECONOMY

A mixed economy is a hybrid of command and market economies. What happens is that there are government has control over goods and services in the economy via things like higher taxes, welfare distribution, etc.

The government also can control companies to some degree with regulations. It isn't necessarily socialist or communist as the government doesn't have complete control, but it does have more control over the economy, and this tends to fall on a spectrum. Mixed economy can be an umbrella term for different combinations with companies and the government.

Examples of countries with mixed economies include France and the United States.

soil erosion in Iran

The removal of fertile topsoil by the action of wind, rain and river water is called soil erosion.

Soil erosion is the process of detachment of soil particles from the parent body or disturbance of the soil structure is known as soil erosion. Generally, soil erosion is called as the creeping death of the soil. Soil erosion is considered as negative soil pollution.

Causes of Soil Erosion:

Soil loss is maximum in the region with high population densities. Globally the present rate of soil erosion is over 2500 million tonnes/year. The chief causes of soil erosion are:

1. Land-use changes involving the destruction of forests and grasslands for expansion of agriculture and other commercial activities. 

2. Overgrazing of pastures. 

3. Fallowing of land for a longer duration. 

4. Overuse of chemical fertilizers under intensive cultivation practices destroys the soil structure consequently the soil becomes susceptible to erosive forces. 

5. Shifting cultivation by tribal population. 

6. Continuous cultivation of the same crop.

Imagine that an impact occurred on the continental plate millions and millions of years ago, leaving behind an impact crater near the right side of the base of the volcano. Why would there be little evidence of this impact crater found today

Answers

Answer:

erosion would erode the surrounding area making less obvious and filled in by hardened magma leaving volcano over millions of years i think. Would leave little impact of the crater. Also growth of plants over years in ash-rich, fertile soil

Explanation:

Volcanic craters may be connected with a cone or flanks. Flows may also be present. Impact craters can be distinguished from volcanic craters by having center peaks, ejecta, high rims, and floors that are lower in elevation than the surrounding topography.

What is a volcanic crater called?

A caldera is a depression formed when a volcano's magma chamber is emptied in an explosive eruption. Without any structural support below, the terrain surrounding the erupting volcanic vent or vents collapses internally, forming the bowl-shaped caldera.

When an asteroid or meteorite collides with the surface of a bigger solid object, such as a planet or moon, an impact crater is generated. This item must be moving extremely fast—many thousands of miles per hour—in order to generate a proper impact crater.

Uniformitarianism means:________. a. neither the scientific past nor the future can be predicted because physical laws change over time. b. earth's surface, including the oceans and continents, has always been the same and will always remain unchanged. c. geologic processes on Earth all operate at roughly the same speed, which has not changed over time. d. geologic processes that operate today operated in the past at about the same speed.

Answers

Answer:

Uniformitarianism means:

d. geologic processes that operate today operated in the past at about the same speed.

Geologists study present geologic processes, whether they are sudden, like an earthquake, or slow, like the erosion of a river valley, to gain insight into the past. This is known as uniformitarianism.

Thus, option D is correct.

Who made uniformitarianism?

The theory of uniformitarianism was developed by Charles Lyell in the 19th century and is based on the writings of James Hutton. According to this hypothesis, the forces and processes that can be seen at the surface of the earth are the same ones that have sculpted the planet's terrain throughout natural history.

The belief that the same natural laws and processes that govern the universe today and have always governed it in the past and apply to all of it is known as uniformitarianism, also known as the Doctrine of Uniformity or the Uniformitarian Principle. Today, we accept uniformitarianism as genuine and understand that major catastrophes like earthquakes, asteroids, volcanoes, and floods are a regular part of the earth's cycle.
