What conditions make for a violent volcanic eruption?
OA. Magma with low gas content
OB. Magma with low viscosity
OC. Magma with high silica content
OD. Magma that can flow easily

Answers

Answer 1

Answer: B

Explanation:

Magma with low viscosity

Answer 2

Magma that has high content of silica will lead to a violent volcanic eruption. Thus, the correct answer is option C.

What kind of magma results in violent volcanic eruption?

Magma that has a high content of silica will have high viscosity. This is due to the bond formation between silicon and oxygen, forming a Si-O tetrahedron.

These tetrahedra combine with each other and result in polymerization which increases the resistance of the liquid to flow. This type of thick magma does not flow easily and will result in an explosive eruption.

High amount of silica causes a lot of gas to be trapped in the volcano.  High-viscosity magma does not allow for the exsolution of gas bubbles.

Thus, the gas bubbles will be trapped inside and increase pressure on the magma column to explode. The trapped gas thus provides the driving force for the explosion.

Thus, the correct answer is option C.

Her teacher replied, "I don't know. See if you could find out."
So Belinda did a lot of research in the library and come upon the idea that
eating carrots will make turtles go faster. She decided to test her ten turtles.
She fed five turtles their normal turtle food. She fed the other five carrots. All
the turtles got their normal sleep and water requirements. Then, after a week

Which evolutionary mechanism increases inheritable variations

Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift

Answers

Answer:

Recombination Of Genes

Explanation:

Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.

What are genetic variations in a population?

Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.

Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.

Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.

Therefore, option A is correct.

Mrs. Jones took care of the boy's hunger.
The boy asked for the money to buy shoes.
Mrs. Jones taught the boy to have manners.
The answer is the boy asked for money

Answers

Answer:

The characters learned to respect each other enough to discuss why the boy tried to grab the purse.

Explanation:

In the short story "Thank You, Ma'am" by Langston Hughes, a young, hungry boy was about to rob a woman of her purse. But as circumstances would turn out, he was unsuccessful in that attempt but then learned a valuable lesson from the very woman he had targeted.

One conflict that was resolved in the resolution was that both of the characters, Mrs. Luella Bates Washington Jones and Roger, learned to respect one another. By her act of inviting him to her home and preparing food for him, Roger also came to respect and trust the woman. It was this faith that helped them discuss the events that led to Roger's failed attempt of robbing Mrs. Jones, and Roger left the house with a sense of appreciation and a change of heart.

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere

Answers

Answer:

B

Explanation:

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.

Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.

Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.

The correct option is B.
