How do convection currents in the atmosphere form?

A Warming air expands, becomes denser, and sinks. As the air sinks, it displaces cooler, less dense air which rises
B Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down
C Cooling air contracts, becomes denser, and sinks. As the air sinks, it displaces warmer, more dense air which rises
D Cooling air contracts, becomes less dense, and rises. As the air rises, it pushes warmer, more dense air down

Answers

Answer 1

Answer:

B. Warming air expands, becomes less dense, and rises. As the air rises, it pushes cooler, more dense air down.

Explanation:

The options D and A can be eliminated because when a gas expands without gaining additional mass, it will become less dense; when a gas contracts without losing mass, it becomes more dense. Therefore, these two options conflict with the idea of density and cannot be true.

Option B is superior to Option C because convection currents are typically portrayed as beginning with the rise of warm air, which displaces/is replaced by cooler, dense air from the upper atmosphere. While Option C is similar, it describes the opposite series of events.

What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?(this is for gizmos lab carbon cycle)

Answers

Answer: When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere.

9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.

What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?

According to the Intergovernmental Panel on Climate Change, the average annual increase in carbon dioxide concentration from 2000 to 2009 was about 1.9 parts per million (ppm) per year, of which about 55% came from the burning of fossil fuels and industrial processes, and about 45% came from land-use change, primarily deforestation.

Thus, in terms of actual amounts, this translates to roughly 9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.

Living things are mostly made up of four elements: carbon, hydrogen, nitrogen, and oxygen. Describe how plants and animals obtain these elements.

Answers

Answer:

Explanation:

Animals obtain carbon by eating and gaining nutrients. This gives them carbon. They get hydrogen by water and glucose. They get nitrogen from food.

Animals obtain these essential elements through the consumption of food and water on basis of their mode of nutrition. While plants directly synthesize these elements with the help of the process known as photosynthesis.

What are the roles of these four elements?

Carbon is considered the building block of living creatures. While other elements like oxygen, nitrogen, and hydrogen are also required by these living entities in order to complete their life cycle, perform growth and development, energy synthesis, metabolism, etc.

The process of obtaining these essential elements in plants and animals differs a lot. This is because the mode of nutrition for both living entities varies.

Plant being autotrophs synthesize their food through photosynthesis and takes essential nutrients from the soil. On contrary, animals get these elements by eating other animals or plant-derived products.

B. Sexual reproduction
C. Mitosis
D. Somatic cells

Answers

Answer:

B. Sexual reproduction

Explanation:

Reproduction in living organisms, which is the process of creating new copies of a particular species, can occur asexually or sexually. The asexual method of reproduction involves only one organism however, the sexual reproduction involved two organisms of different sexes (male and female).

In sexual reproduction, the male organism produces male gametes (sperm) while the female organism produces female gamete (egg). These two sex cells or gametes come together in a process called FERTILIZATION to form one new cell called ZYGOTE, which eventually develops into a new organism.
