This is the process of chemical weathering.

This is the chemical reaction between Carbonic acid  (H2CO3), i.e. Acid Rain, and the Limestone (CaCO3), i.e. Calcite. The product of this reaction is Calcium Bicarbonate Ca(HCO3)2, which is soluble and is washed away by the rain.

A line graph titled Population (millions) of the largest cities in Brazil shows rank from 1 to 10 on the x-axis and population in millions on the y-axis from 0 to 12 by twos. In order from 1 to 10: Sao Paulo = more than 11 million, Rio de Janeiro = 6 million, Salvador = 3 million, Brasilia = less than 3 million, Curituba = 2 million, Manaus = less than 2 million, Recife = more than 1 million, Belem = more than 1 million, P Alegre = more than 1 million, Guarulhos = more than 1 million.

Analyze the size of the largest cities in Brazil, as shown on the graph above. Does Brazil follow rank-size distribution?

Answers

Answer:

This graph shows the population distribution of Brazil’s largest cities. The vertical axis shows the population, and the horizontal axis shows the rank of the city. The shape of this graph seems to follow rank-size distribution closely. It shows that the population of Rio de Janeiro is about half that of Sao Paulo and the population of Salvador is about half that of Rio de Janeiro.

If there are letter choices then the answer is B.

Explanation:

Hope this Helps :)

The answer is option B.

This graph shows the population distribution of Brazil’s largest cities. The vertical axis shows the population, and the horizontal axis shows the rank of the city. The shape of this graph seems to follow rank-size distribution closely. It shows that the population of Rio de Janeiro is about half that of Sao Paulo and the population of Salvador is about half that of Rio de Janeiro.

Is Brazil a rank-size rule or a primate city?

Brasilia should have 2.5 million but is close to 2 million, and Fortaleza is right at the predicted population of 2 million people. Therefore, Brazil follows the rank size rule because of how close the actual population of cities are to the predicted populations.

Sociologists and public policy makers refer to the way society is changing as "cultural change." The outcome is the development of new social structures as well as new cultural traits, behavioral patterns, and social standards in society.

Trade facilitated the spread of culture. Diverse civilizations, including the nomadic, village, and urban cultures, were mingled via the exchange of ideas, beliefs, material commodities, and tools. Another factor in the spread of culture was written documents.

What is the main cause of cultural change?

Environmental factors, technological advances, and interactions with other cultures are just a few of the many factors that can lead to cultural change. Contact between societies has an external impact on cultures and has the potential to cause (or not) social change and alter cultural practices.

As a result of people traveling around the world to do trade, ideas and cultures are diffused. They move, encountering new concepts and cultural norms along the way, as do the individuals they meet.

The main barriers to the growth of international trade are linguistic and cultural barriers. The expenses of commerce will increase as differences grow. Previous research has demonstrated that multinational corporations like doing business with nations that share their languages and cultures.

Answer:

A and B

Explanation:

These statements about Nan Province, Thailand, and Phillips County, Montana, mark a difference between these two places are:

About 10 percent of Nan is made up of hill tribes.Phillips County is mostly Christian. Thus, option (a) and (b) is correct.

What is Phillips County?

On May 1, 1820, Phillips County was created. There are 64 counties in the American state of Colorado, one of which being Phillips County. The country's population should be roughly 18,151 people, and the area must be covered by 1,884 km2.

Nan is a rural province in northern Thailand that borders Laos and is well-known for its several national parks. Though we live in a rush most of the time, time seems to move more slowly in Nan.

The difference between the two nations is that whereas Phillips County is primarily Christian, Nan is home to around 10% of hill tribes.

Therefore, option (a) and (b) is correct.

Match the words with their definitions.

Answers

Answer:

fault- molten rock

sill - horizontal intrusion

uplift- natural , upward movement of rock layers

d(y)ke- vertical intrusion

Explanation:

Uplift and sill are movements of layers differing in their direction of movement, where sill is in horizontal direction and uplift is in vertical direction. Fault refers to the cracks in the earth's crust.

The geological terms can be matched with their definitions as follows:

1. diyke - molten rock

It is formed when magma or molten rock is injected into fractures or cracks in the surrounding rock and solidifies.

2. sill - horizontal intrusion

A sill is an intrusive rock formation but is characterized by its parallel orientation to the existing rock layers.

3. uplift - natural, upward movement of rock layers

Uplift refers to the vertical movement of Earth's crust, causing the elevation of a particular region. It can occur due to tectonic forces, such as the collision of continental plates or the upwelling of molten material from the mantle.

4. fault - a crack across rock layers caused by moving plates

A fault is a fracture or break in the Earth's crust along which movement has occurred. Faults can be caused by tectonic forces, such as the collision or separation of lithospheric plates.

How does gravity affect the inner planets? (site 2)

Answers

Answer:

Because of gravity, the inner planets of our solar system have a shorter orbital period around the sun than the exoplanets do. For example, the sun's gravitational pull makes Mercury have a orbital period of 88 days, versus Neptune, who takes 165 Earth years to orbit the sun.

The Sun's gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. The closer the planet is to the Sun, the greater the pull of the Sun's gravity, and the faster the planet orbits.

Compare and contrast oceanic crust with continental crust. In your answer, be sure to consider the features of the two types of crust, such as thickness and composition. For example, what are the major elements in each type of crust?

Answers

Answer:

“Crust” describes  the outermost shell of a terrestrial planet. Our planet’s thin, 40-kilometer (25-mile) deep crust—just 1% of Earth’s mass—contains all known life in the universe.

Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.

Earth’s layers constantly interact with each other, and the crust and upper portion of the mantle are part of a single geologic unit called the lithosphere. The lithosphere’s depth varies, and the Mohorovicic discontinuity (the Moho)—the boundary between the mantle and crust—does not exist at a uniform depth. Isostasy describes the physical, chemical, and mechanical differences between the mantle and crust that allow the crust to “float” on the more malleable mantle. Not all regions of Earth are balanced in isostatic equilibrium. Isostatic equilibrium depends on the density and thickness of the crust, and the dynamic forces at work in the mantle.

Just as the depth of the crust varies, so does its temperature. The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit).
