What are the primary factors that determine whether a volcano erupts explosively or relitivly quietly.

Answers

Answer 1
Answer:

The intensity of the volcano eruption depends on the character and composition of the magma.

Further Explanation:

Magma is formed when the lower crust or upper mantle of the earth is melted. This magma is discharge by a volcano, which is referred to as a vent or opening through which magma is released. Many factors can trigger a volcanic eruption. The major reasons are:

  • The density of the magma
  • Pressure from the gases present in the magma
  • Addition of a newly formed magma into an already filled magma chamber

The intensity of volcanic eruption could be of two types, explosive and quite. There are two primary factors which determine whether the volcanic eruption is quite or explosive named are:

  • Viscosity
  • Content of gases in magma

As the viscosity and gas content of magma is low, then volcanic eruption is less explosive or quite. On the other hand, if the viscosity and gas content is high, then the volcanic eruption is explosive.

Answer 2
Answer: chemical composition,temperature, viscosity
different chemicals in an erupting volcano's magma affects the temperature, which in turn affects the viscosity, which affects the eruption itself
for example, less silica content in the magma means lower temperature which means the lava cools down faster and hardens faster, which means the viscosity increases, which in turn results in  relatively quiet explosion.

Answers

Answer:

A compound has a ph of 6 in solution where very little of it has ionized the compound is a weak acid.

Explanation:

As you may know the pH scale is a scale that measures the degree of acidity of the substances. This scale has values ranging from 0 to 14.

On the pH scale, substances whose pH is less than 7 are classified as acidic, those with a pH greater than 7 are classified as basic, and those with a pH around 7 are considered neutral. The further away from number 7 the stronger the acid or base is. In this case, if a substance has a pH of 6, it means that that substance is a very weak, almost neutral acid.

The compound is known as a weak acid

Which method would allow you to study the behavior of a tiger in its native habitat in India?

Answers

The answer is field investigation.

A field investigation includes observation of free-living animals in their natural habitat without affecting them, their behavior, or their habitat. So, observation of tigers' activity in their native habitat is an example of the field investigation. The investigator would simply observe their behavior, not affecting the tigers in any way.

snow hail sleet rain These are all a source of __________ on the Earth. A) wind B) water C) climate D) natural disaster

Answers

Answer: B). Water

Explanation:

Snow, hail, sleet and rain are the forms of precipitation. These form due to accumulation of water vapor in the atmosphere which lead to the formation of clouds. The clouds when condense lead to the formation of precipitation in the form of snow, hail, sleet, and rain.

b. water. because snow has water molecules. hail is when ice falls. sleet consists of snow. and rain is falling water.
