1) What gas needed to be established within the Earth's atmosphere before 1 point
the atmosphere was able to absorb and maintain heat? Hydrogen
Nitrogen
Oxygen
Carbon dioxide

Answers

Carbon dioxide. Greenhouse gases trap heat

Carbon dioxide gas needed to be established within the Earth's atmosphere. Light is absorbed by greenhouse gas molecules in the atmosphere, preventing part of it from exiting the Earth, and this warms up the atmosphere and boosts the average temperature of the planet. Option D is correct.

What is the significance of  Carbon dioxide to the atmosphere?

Carbon dioxide is required for human internal respiration. Internal respiration is the process by which oxygen is transferred to and carbon dioxide is removed from human tissues. Carbon dioxide protects the blood's pH, which is critical for survival.

Most animals, which exhale carbon dioxide as a waste product, are natural sources of carbon dioxide. Carbon dioxide emissions are mostly caused by human activities such as the combustion of coal, oil, or natural gas. The molecules of greenhouse gas in the atmosphere absorb light, preventing some of it from leaving the Earth.

The presence of carbon dioxide in the atmosphere heats the earth, resulting in climate change. In fewer than 200 years, human activities have increased the carbon dioxide concentration of the atmosphere by 50%.    Carbon dioxide gas has to be introduced into the Earth's atmosphere.

Therefore, option D is correct.

Answers

Some reasons why rich nations see a decline in their birth rates include:

Increased access to education for women Improved access to family planning and contraception

Why are rich nation populations dropping ?

As women gain more access to education and employment opportunities, they tend to delay childbearing and have fewer children. This is because they prioritize their careers and personal goals over starting a family at a young age.

With improved access to family planning and contraception, people are better able to plan and space their children. This means they can choose to have fewer children, or to have them later in life.

Answers

In the outer core of the earth's interior, the melting point of the rock is inferred to be lower than the actual temperature of the rock.

In geology, the physical composition of the planet earth shows that is composed of three distinct layers: crust, mantle, and core.

The earth's interior is called the core and the core is further divided into two segments: the outer core and the inner core.

The outer core lies adjacent to the mantle while the inner core is the center point.

Generally, the melting point of a solid substance decreases as pressure increases. So if we go deeper into the earth we will see that the pressure is quite high in the core due to which the melting point of rocks decreases than their actual temperature.

Is there a gun that can shoot a bullet into orbit around the moon?

Answers

No, their is no such gun that can shoot a bullet into orbit around the moon and also it's not possible scientifically.

An object is launched into space using a massive gun- or cannon-like apparatus, known as a space gun or a Verne gun because of its depiction in Jules Verne's From the Earth to the Moon.

Therefore it's possible that space guns will offer an alternative to rocket launch. Space weapons have been theorised to be able to send spacecraft beyond Earth's gravitational pull and into other regions of the Solar System by travelling faster than the planet's escape velocity of roughly 11.20 km/s.

A space gun would only be able to launch freight, fuel, or ruggedized satellites due to the high g-force that a ballistic projectile fired in this way is expected to face. This would prevent it from securely launching people or delicate instruments.

Sparke describes the process whereby new regional trading blocks are formed as examples of deterritorialization. True or False?

Answers

The statement that "Sparke describes the process whereby new regional trading blocks are formed as examples of deterritorialization" is TRUE.

According to Sparke, the formation of new regional trading blocks is an example of deterritorialization, as these blocks lead to a reduction in the significance of national borders in economic exchanges.

The creation of trading blocks promotes greater economic integration between countries, which can result in the erosion of traditional territorial boundaries.

This process facilitates the flow of goods, services, and capital across borders, ultimately fostering a more globalized economy.

As a result, the importance of geographic territories is diminished, illustrating the concept of deterritorialization in the context of regional trading blocks.
