How does a seismograph detect and record seismic waves?

Answers

Answer 1

Answer:

Seismic waves are studied by geophysicists called seismologists. Seismic wave fields are recorded by a seismometer, hydrophone (in water), or accelerometer. The propagation velocity of seismic waves depends on density and elasticity of the medium as well as the type of wave.

How would a strong government help you?

Answers

Answer:

Weak politics may make for good economics. This is contrary to the proposition that the Government presented to the British electorate, that the Government needed a strong mandate to negotiate Brexit. Now, among the myriad uncertainties facing the country there is one certainty. The UK will have a weak government, led by a weak Prime Minister. Weak governments will not be able to make big changes in economic policy. But that is good, not bad. Think about the three aspects of economic policy: monetary, fiscal and structural.

Answer:

I'm not too entirely sure of this, but I based it off on what I thought

Explanation:

Weak Government: A small government can't profit much off to your country, but they are much more careful of public spending and what to buy and what not. On what can be beneficial for their country and society. I think if they structure this off correctly, overtime they will gradually grow stronger.

Strong Government: A strong government definitely has a huge amount of money. I'm sure they would NEED to use it properly, so they can help out their country. They also might as well have a huge line of military forces.

a short summary about drought 90words​

Answers

Answer:

Drought is a dangerous condition which decreases the quality of life. It is termed as a natural disaster with harmful effects. A drought usually occurs when a region faces a shortage of water. This is mainly due to lesser rainfalls. In addition, droughts have proven to be fatal for mankind and wildlife as well.

Moreover, drought is the most dangerous for a farmer. As they do not have an ample supply of water, their crops dry out. This becomes a reason for worry as it is their sole income. Furthermore, drought also leads to various other problems for the environment and mankind.

Causes of Drought

Drought is caused due to various reasons. One of the main reasons is deforestation. When there will be no trees, the water on land will evaporate at a faster rate. Similarly, it lessens the soil capacity to hold water resulting in evaporation.

Moreover, lesser trees also mean lesser rainfall which eventually leads to drought.

Furthermore, as the climate is changing, the water bodies are drying up. This results in a lower flow of surface water. Therefore, when the rivers and lakes will dry out, how will the people get water? In addition, global warming is a major cause of this. The greenhouse gas emitted causes the earth’s temperature to rise. Thus, it results in higher evaporation rates.

Subsequently, excessive irrigation is also a great cause of droughts. When we use water irresponsibly, the surface water dries up. As it does not get ample time to replenish, it causes drought.

Find d(21) in the sequence given by d(n) = 2+0.4(n-1). d(21)=

Answers

Answer: 8

Explanation:

From the question, we are informed that we should find d(21) in the sequence given by d(n) = 2+0.4(n-1). This will be:

d(n) = 2+0.4(n-1)

d(21) = 2 + 0.4(21 - 1)

= 2 + 0.4(20)

= 2 + 8

= 10

Therefore, based on the above calculation, we can deduce that the 21st term is 8.

Deposition is the removing of material from an area.

True or False

Answers

Answer:

true

Explanation:

sorry if im wrong

True, Deposition involves removing of material from an area.

Geographically, Deposition refers to a process where soil, rocks and sediments are moved to a landmass through a medium such as wind, water, sea, ice, gravity etc.

The medium that transport these sediment are called "eroding agent".

When an eroding agent runs out of energy, the sediment and other particle been transported forms deposit thereon.

In conclusion, the process of Deposition involves the removal of material from an area to another area.

Which type of magma would you expect to produce the most explosive volcanic eruption?

A. low percentage of Silica (SiO2) with high gas content

B. low percentage of Silica (SiO2) with low gas content

C. high percentage of Silica (SiO2) with high gas content

D. high percentage of Silica (SiO2) with low gas content

Answers

Answer:

C

Explanation:

A high percentage of silica means that the viscosity of the magma is greater, this means it is more explosive.

Higher gas means more pressure on the magma so a more explosive eruption.

The high percentage of Silica with high gas content of magma would you expect to produce the most explosive volcanic eruption. Thus, option C is correct.

What is a volcanic eruption?

A volcano releases magma, which causes a volcanic explosion. Explosions can indeed be catastrophic or fairly quiet and expansive. Lava flows result from effervescent explosions, whereas ashes and ionized plasma are omitted in the environment.

As there will be a large amount of silica if present inside and also there will be a high gas content as well, as magma will be reacting with each other and creating a great amount of pressure.

The result will be a great amount of pressure that will intensify the eruption that will happen. Therefore, option C is the correct option.

a. Erosion is greater on a flat plain because the gentler slopes

b. Erosion is less because the mountain is covered by a thick layer of clay

c. erosion is less on the mountain because of the abundant rainfall

d. Erosion is greater on the mountain slope because the higher water velocities

Answers

Answer: d. Erosion is greater on the mountain slope because the higher water velocities

Explanation:

The erosion can be defined as the loss of fertile top layer of the soil due to the action of physical agents like water, wind, and others. The mountain slope will offer less resistance against the movement of the materials like soil, sediments, pebbles, stones, and others down the slope. The water will also flow at higher velocity without any resistance on the mountain slope and it will erode the top layer of soil along with other materials like sediments, pebbles, stones, and others.
