The composition of magma is determined by the rock from which it was formed (by melting) and the circumstances of that melting. They are dominated by oxygen and silicon.
The composition of magma is determined by the rock from which it was formed and the conditions under which it was formed. Although mantle magmas contain higher amounts of iron, magnesium, and calcium, they are still almost certainly dominated by oxygen and silicon. Magma is classified into three types: basaltic, andesitic, and rhyolitic, each with its own mineral composition. All types of magma contain a significant amount of silicon dioxide. Iron, magnesium, and calcium are abundant in basaltic magma, but potassium and sodium are scarce.

the capillary fringe is thicker in fine-grained sediments and thinner in coarse-grained sediments. group of answer choices true false
It is true that the capillary fringe is thicker in sediments with finer grains and thinner in sediments with coarser grains.
Capillary fringe: what is it?The subsurface layer known as the capillary fringe is where groundwater seeps up from a water table to fill pores through capillary action. Due to tension saturation, water has filled the pores at the capillary fringe's base. Due to the mix of pore sizes, the saturated portion of the capillary fringe is smaller than the overall capillary rise.
For several feet above the water table, soils may be completely saturated with water if the pore size is small and fairly uniform. The saturated portion will also only rise a few inches above the water table when the pore size is large.
A vadose zone, whose water content decreases with elevation above the water table, is supported by capillary action above the saturated base. The unsaturated zone can be several times thicker than the saturated zone in soils with a wide range of pore sizes.

Explain what role melted water from glaciers has in creating distinguishing landforms
As glaciers melt, they often leave behind additional depositional landforms in addition to moraines.
There is a lot of silt produced by the vigorous grinding operation.
This silt, together with sand and gravel, is carried by rivers of water melting from the glacier and dumped in a region known as an outwash plain in front of the glacier.
This is further explained below.
What is the glacier?Generally, A glacier is a long-lasting mass of compacted ice that is always moving because it is being pushed and pulled by its own weight. When, over the course of many years and maybe centuries, the accumulation of snow is greater than its ablation, a glacier will begin to form.
When glaciers melt, they leave behind various depositional landforms in addition to moraines.
These landforms are called moraines. The intensive grinding process results in a significant amount of silt being produced.
This silt, together with sand and gravel, is carried by the streams of water that originate from the glacier's melting and is deposited in a region that is known as an outwash plain in front of the glacier.

faults can be recognized in the field, even if the fault plane itself is not exposed, because
Rock units offset by faults allow for the identification of faults in the field even when the fault plane itself is not accessible.
In geology, a fault is a flat or slightly curved fracture in the rocks that make up the Earth's crust where compressional or tensional forces cause the rocks on either side of the fracture to move relative to one another. Few centimeters to many hundreds of kilometers is the range in length of a fault, while less than a centimeter to many hundreds of kilometers is field the range in displacement along the fracture surface (the fault plane).
In some cases, the movement is dispersed along a belt of field faults that is hundreds of meters wide and is made up of numerous separate faults. Flaws are distributed differently across different geographic regions; some big areas have essentially no faults, while others have countless faults.

why reducing the county s dependency on coal WOULD have a negative impact on the economy
Answer: negative impact on trade balance, exchange rate, and the growth of other sectors
Coal mining also has a negative impact on the trade balance, exchange rate, and the growth of other sectors, particularly when commodity prices decrease.
Explanation:The coal industry asserts that continued investment in coal is needed to grow developing economies and combat poverty. The logic runs that coal is necessary to provide the energy required for industrialisation, the process of structural change from an agrarian society to one based primarily on manufacturing. Historically, industrialisation has enabled some countries to rapidly increase economic productivity, employment and income levels. The consumption of coal and other fossil fuels for industrialisation, however, is a major cause of global warming. A shift away from coal is necessary for climate protection.

The problems that come with a balanced population pyramid is that each location will be allocated resources equally even, if there are lesser revenue generated from therein.
What is a population pyramid?Basically, a population pyramid refers to the graph that shows the age-sex distribution of a given population such as the graphic profile of the population’s residents. On the graph, the gender is shown on the left/right sides, age on the y-axis and the percentage of population on the x-axis.
This population pyramids are mostly used by demographers as a tool for understanding the make-up of a given population whether of a city, country, region or the world at large. However, the population pyramid does not tell you the actual population in numbers, rather, it does displays the percentages and shows what portion of people fall into each cohort.

Subduction is the time period while the oceanic plate movements under the a lot lighter continental plate. The downward grade could be very steep and while the rock turns into molten it's going to then upward thrust up and shape a volcano because it releases the stress from the construct up.
The required details for Subduction in given paragraph
Accrection happens while the oceanic plate slowly comes collectively with a continental plate accordingly the downward grade isn't as steep. The end result is a sluggish buildup of the crust upward and outward. Subduction is a geological system wherein the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the much less dense lithosphere of a 2d plate, the heavier plate dives under the second one plate and sinks into the mantle. A vicinity in which this system happens is called a subduction zone, and its floor expression is called an arc-trench complex.
The system of subduction has created maximum of the Earth's continental crust. Rates of subduction are usually measured in centimeters according to yr, with the common price of convergence being about to 8 centimeters according to yr alongside maximum plate boundaries.

What is a plate boundary?In geography, a plate boundary refers to a 3 dimensional zone across which there is a significant change in the velocity of the motion of one lithospheric plate in relation to the adjacent other lithospheric plate. The plate boundary is the location that are associated with some geological events such as earthquakes and creation of topographic features like mountains, volcanoes, mid-ocean ridges, oceanic trenches etc.
Therefore are three types of plate boundary which includes:
Convergent boundary: It is an area on Earth where two or more lithospheric plates collide. When one plate eventually slides beneath the other, the process is known as subduction which is responsible for occurence of earthquakes occur.Divergent boundary: It is the area two tectonic plates are moving away from each other. The divergent boundaries within continents initially produce rifts which eventually become rift valleys.Transform boundary: This is the area that had fault along a plate boundary where the motion is predominantly horizontal.

what separates the troposphere and stratosphere
Question: ) what separates the troposphere and stratosphere ??
Answer: The troposphere is bonded on the top by a layer of air called the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth.
Explanation: Troposphere:
It is the lowermost and densest layer of the atmosphere. It spreads till a height of about 8 km over the pole but over the equator, it is 18 km. About 80 percent or more of the total mass of the atmosphere lies in this layer. With increase in height, the temperature keeps on decreasing till the limit of this layer. This is said to be the normal lapse rate. On an average, the decrease in temperature with height is 60 Celsius per km. The upper boundary is known as the troposphere , placing between 8 and 18 km. At this level, the average temperature spreads to minus 500 to minus 600 Celsius. Water vapour is available in this layer in plenty and about 99 percent of the total atmospheric water vapour is focused here but wide variation is seen in terms of height and longitudes. Vapour plays a very vigorous role in regulating the temperature of the earth by producing greenhouse effect.
Stratosphere:
The Stratosphere is the upward second layer as well as the middle layer of the atmosphere. It starts from tropopause to approximately a height of 50 km. The temperature at the tropopause remains nearly constant till the height of 20 km. After that, it starts increasing and continues to increase till the height of 50 km. At this level, the projected temperature is about minus 100 to minus 150 Celsius. Though the temperature is on advent, there is no atmospheric turbulence. This layer is completely free from clouds and other weather settings.
