Notice how the melting curve for wet peridotite occurs at much lower temperatures than the melting curve for dry peridotite at similar depths and pressures. Of course, rocks can also be partially melted by heating them up. Crustal rocks are primarily melted by temperature increases. Determine the primary means of melting that would occur at divergent boundaries, convergent boundaries, and within a plate (intraplate).

Answers

Answer 1

Answer:

In the convergent boundary, as the plate go deeper pressure increases and temperature also and when the pore water will be released they helped in partial melting. So while the condition will be there as at the melting curve, then an increase in temperature will produce huge partial melt due to presence of water. As shown in the above curves of melting curve of wet peridotite.

In the intraplate melting, the pressure is not changing only temperature of the peridotite is changing . So when temperature will increase it will start to melt (As shown in figure).

In divergent boundary the melting occurs due to decompression. There is no role of temperature here . As temperature is almost constant and the rock will come up it will undergo decompression and will produce melt (As shown in fig 3, decrease in pressure results in melting).

Explanation:

One person buys a compact sedan that costs $21,000 and gets 25 miles per gallon. Another person pays $25,000 for the hybrid version of the same compact sedan, which gets 50 miles per gallon. Each owner drives 12,000 miles per year and plans on keeping the vehicle for 10 years.

A gallon of gas emits 20 pounds of CO, when burned in an internal combustion engine. The average cost of a gallon of gas over the 10-year ownership period is $3.00.


a. Calculate how many gallons of gas each vehicle uses per year.

b. Calculate the cost of the gas that each vehicle uses per year.

c. Calculate the amount of CO, that each vehicle emits per year.

Answers

Answer:

The answer is below

Explanation:

a) compact sedan costs $21,000 and can go 25 miles per gallon. If owner drives 12000 miles per year, the number of gallons needed is:

number of compact sedan gallons needed per year = distance covered in a year / distance covered per gallon = 12000 miles per year / 25 miles per gallon = 480 gallons

Hybrid compact sedan costs $25,000 and can go 50 miles per gallon. If owner drives 12000 miles per year, the number of gallons needed is:

number of hybrid compact sedan gallons needed per year = distance covered in a year / distance covered per gallon = 12000 miles per year / 50 miles per gallon = 240 gallons

b) cost of compact sedan gas needed per year = number of gallons needed * cost of gallon = 480 gallons * $21000 = $10,080,000

cost of hybrid compact sedan gas needed per year = number of gallons needed * cost of gallon = 240 gallons * $25000 = $6,000,000

c) Amount of CO emitted by compact sedan gas vehicle = number of gallons * 20 pounds of CO per gallon = 480 gallons * 20 pounds of CO = 9600 pounds

Amount of CO emitted by hybrid compact sedan gas vehicle = number of gallons * 20 pounds of CO per gallon = 240 gallons * 20 pounds of CO = 4800 pounds

a) compact sedan costs $21,000 and can go 25 miles per gallon.

If owner drives 12000 miles per year, the number of gallons needed is:

Number of compact sedan gallons needed per year

= distance covered in a year / distance covered per gallon

= 12000 miles per year / 25 miles per gallon

= 480 gallons

Hybrid compact sedan costs $25,000 and can go 50 miles per gallon. If owner drives 12000 miles per year, the number of gallons needed is:

number of hybrid compact sedan gallons needed per year

= distance covered in a year / distance covered per gallon

= 12000 miles per year / 50 miles per gallon

= 240 gallons

b) Cost of compact sedan gas needed per year

= number of gallons needed * cost of gallon

= 480 gallons * $21000

= $10,080,000

Cost of hybrid compact sedan gas needed per year

= number of gallons needed * cost of gallon

= 240 gallons * $25000

= $6,000,000

c) Amount of CO emitted by compact sedan gas vehicle

= number of gallons * 20 pounds of CO per gallon

= 480 gallons * 20 pounds of CO

= 9600 pounds

Amount of CO emitted by hybrid compact sedan gas vehicle

= number of gallons * 20 pounds of CO per gallon

= 240 gallons * 20 pounds of CO

= 4800 pounds

Answers

Given:

A figure of a triangle.

To find:

The remote interior angles of angle 1.

Solution:

Exterior angle theorem: According to this theorem, an exterior angle of a triangle is equal to the sum of the two opposite interior angles of that triangle.

Those two interior angles of the triangle are called remote interior angles of that exterior angle.

From the given figure it is clear that the angle 1 is an exterior angle, and the two opposite interior angles of the triangle are angle 5 and angle 5.

[tex]\angle 1=\angle 5+\angle 6[/tex]            (Exterior angle theorem)

So, ∠5 and ∠6 are the remote interior angles of ∠1.

Therefore, the correct options are B and F.

How will climate affect the recovery from tsunamis?

Answers

Answer:

This means small tsunamis that might not be deadly today could wreak havoc in the future.

“Our research shows that sea-level rise can significantly increase the tsunami hazard, which means that smaller tsunamis in the future can have the same adverse impacts as big tsunamis would today,” said Robert Weiss, a professor of geosciences at Virginia Tech.

Weiss worked with the Earth Observatory of Singapore, the Nanyang Technological University and the National Taiwan University to map the dangers of future tsunamis.

He explained that small tsunamis generated by earthquakes occur frequently around the world, and may eventually be far more hazardous.

The researchers created computer-simulated tsunamis at current sea levels and then compared them to the same simulations with sea-level increases of 1.5 feet and 3 feet.

Weiss’ simulations charted the effect of a tsunami in Macau, a densely populated region in southern China.

The area is generally considered safe from the threat of tsunamis. At current sea levels, an earthquake would need to measure a magnitude of 8.8 or higher to cause “widespread tsunami inundation” in Macau.

But with a sea-level rise of 1.5 feet, the frequency of tsunami-induced flooding in the simulation rose by 2.4 times.

And for the 3-foot increase, the frequency of flooding rose to 4.7 times.

“We found that the increased inundation frequency was contributed by earthquakes of smaller magnitudes, which posed no threat at current sea level, but could cause significant inundation at higher sea-level conditions,” said Lin Lin Li, a senior research fellow at the Earth Observatory of Singapore.

Scientists used 5,000 tsunami simulations generated from “synthetic earthquakes” in the Manila Trench.

The Manila Trench is the main hazard point for large tsunamis in the South China Sea.

It hasn’t experienced an earthquake larger than magnitude 7.8 since the 16th century.

But study co-author Wang Yu said that the region shares many similarities to the source areas that led to the deadly 2004 Indonesian earthquake and Japan’s 2011 quake – both of which led to huge tsunamis.

In the future, it’s possible that smaller-magnitude earthquakes could instigate similar events – all thanks to rising sea levels.

It’s estimated that sea levels in the Macau region will increase by 1.5 feet by 2060, and by 3 feet by 2100.

“The South China Sea is an excellent starting point for such a study because it is an ocean with rapid sea-level rise and also the location of many mega cities with significant worldwide consequences if impacted,” explained Weiss.

“Sea-level rise needs to be taken into account for planning purposes, for example for reclamation efforts but also for designing protective measures, such as seawalls or green infrastructure.”

He went on: “What we assumed to be the absolute worst case a few years ago now appears to be modest for what is predicted in some locations.

“We need to study local sea-level change more comprehensively in order to create better predictive models that help to make investments in infrastructure that are or near sustainable.”

Sea levels aren’t just rising in the South China Sea – they’re rising globally.

The rise is largely attributed to global climate change: partly due to warming seas, causing “thermal expansion” of the water, and partly due to melting ice sheets and glaciers on land.

It’s estimated that we’ll see a rise of between 1 and 8 feet during the 21st century.

The force of gravity between two objects decreases as the distance between the two objects increases.

Answers

Answer:

True

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

True, the gravitational force between two objects weakens as the distance separating them increases.

Gravitational force is a fundamental force of nature that exists between objects with mass. It is responsible for the attraction between objects and governs the motion of celestial bodies, such as planets and moons.

The magnitude of gravitational force is directly proportional to the mass of the objects involved and inversely proportional to the square of the distance between them.

This means that as the distance between two objects increases, the gravitational force between them decreases. Gravitational force plays a crucial role in maintaining the stability and dynamics of the universe, shaping the orbits and interactions of celestial objects.

Therefore, the given statement is true.
