This is a coarsely crystalline igneous rock, so to identify the rock you only need to estimate its composition. Select the option that gives the closest approximation of the proportion of the minerals.
The composition of coarsely crystalline igneous rock are 15% mafic (dark) minerals, 85% felsic (light) minerals.
What is Igneous rock?Igneous rocks are formed when hot, molten rock crystallizes and changes its integrity. The melt originates from deep below the Earth near active plate boundaries or hot spots of volcanoes, then rises toward the surface.
There are two main categories of igneous rocks, are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava (magma) that emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
Therefore, Igneous rocks are 15% mafic (dark) minerals, 85% felsic (light) minerals.

What did President Carter do to upset the Iranians?
Answer:
President Jimmy Carter's activities in regards to Iran were profoundly discussed and caused pressure between the US and Iran. A critical episode that incited the Iranians was the point at which the U.S. government permitted the banished Iranian ruler, Mohammad Reza Pahlavi, to enter the US in 1979 for clinical reasons. The shah had been toppled in the Iranian Unrest, and numerous Iranians saw his entrance into the U.S. as an assault on their nation's freedom and as mediation in their inside issues.
After the shah's appearance in the U.S., a gathering of Iranian understudies assumed command over the American consulate in Tehran, catching 52 American negotiators and residents. The understudies requested the arrival of the shah to Iran to confront preliminary and made a few different solicitations in regards to U.S.- Iran ties. The prisoner emergency endured for 444 days and altogether hurt the connection between the U.S. what's more, Iran.
What are the thermal winds effect?
Answer:
Thermal winds are winds created by differences in air temperature. They are caused by differences in air pressure due to uneven heating of the Earth's surface. As hot air rises, it creates an area of low pressure. This low pressure causes air to be drawn in from other areas of higher pressure, creating winds. As the air cools, it descends and creates an area of high pressure, which draws in air from other areas of low pressure. This creates a cycle of winds that can affect local weather patterns and even global climate.
Answered By Unish ©
Verified Answer ✅
Explanation:
The thermal wind effect is a meteorological phenomenon that occurs in the atmosphere, particularly in the middle and upper levels. It is a result of the interaction between horizontal temperature gradients and the Coriolis force, which is the apparent force that deflects moving objects to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Earth's rotation.
In the thermal wind effect, a horizontal temperature gradient exists between two adjacent layers of the atmosphere. This temperature gradient causes a difference in pressure between the two layers. The Coriolis force then causes air to flow from higher to lower pressure, which creates a wind that is perpendicular to both the temperature gradient and the pressure gradient.
The thermal wind effect is an important factor in the formation of the jet stream, which is a narrow band of strong winds in the upper atmosphere that generally flows from west to east. The temperature gradient between the cold polar air and the warmer air at lower latitudes creates a pressure gradient that drives the jet stream. The Coriolis force then causes the wind to rotate and form the characteristic meandering pattern of the jet stream.

What is Pogrom?A pogrom, which is usually carried out by a dominant group, is a violent assault against a particular ethnic or religious group. Property ruin, theft, and bodily harm, such as murder, and beatings, are frequent components of pogroms. Pogroms have historically been committed against Jews, but also against other marginalised groups like Armenians and Gypsies. Pogroms can cause long-lasting effects on the communities they impact, including trauma and relocation. They are frequently sparked by ingrained prejudice, dread, and a desire for vengeance. Human rights groups have denounced pogroms as being against international law and a violation of fundamental human decency.

why does Ramamurthy think it is important to analyze gender and race in relation to production.
Answer:
Read below
Explanation:
Without additional context, it's difficult to know exactly which Ramamurthy is being referred to or what specific production is being discussed. However, in general, analyzing gender and race in relation to production can be important for a number of reasons.
Firstly, it can help identify patterns of discrimination or bias that may be present in the production process or in the industry as a whole. For example, if women or people of color are consistently underrepresented in certain roles or are paid less than their white or male counterparts, this could be an indication of discrimination or bias.
Secondly, analyzing gender and race can also help ensure that productions are more representative and inclusive. If the production team is diverse and reflects the experiences of a wider range of people, this can help ensure that the final product is more nuanced and thoughtful in its approach to issues related to gender, race, and other forms of identity.
Finally, analyzing gender and race can also help create opportunities for marginalized communities to participate in the production process and gain access to jobs and other resources. This can help address systemic inequalities and promote greater social and economic equity.
a fuel's ____ is the total amount of thermal energy released when a specific amount of that fuel burns.
A fuel's heat of combustion is the total amount of thermal energy released when a specific amount of that fuel burns.
The quantity of heat released when a specific amount of a substance undergoes burning is known as the heat of combustion, also known as the calorific value or the energy value. The term "heat of combustion" is frequently used interchangeably with "calorific value," which is the total amount of energy released after the full combustion of a given mass of a substance in the presence of (enough) oxygen under typical conditions of pressure & temperature.
When hydrocarbons are used as fuels, their potential is typically measured in terms of calorific value, which is based on the combustion reaction they go through with oxygen to produce water and carbon dioxide.

based on what we learned about igneous composition and texture, which of the following statements is true?
Based on what we learned about igneous composition and texture, the true statement is that any composition of magma/lava can cool to form any of the discussed textures, because the two properties are independent from one another.
How do most igneous rock formed?When hot, molten rock crystallizes and solidifies, it forms igneous rocks (from the Latin word for fire). Melt forms deep within the Earth near active plate boundaries or hot spots and rises to the surface. Igneous rocks are classified as intrusive or extrusive based on where the molten rock solidifies.
When magma is trapped deep within the Earth, igneous rock forms. Massive globs of molten rock rise to the surface. Some of the magma may feed volcanoes on Earth's surface, but the majority remains trapped below, where it slowly cools over thousands or millions of years until it solidifies.

what is an equation of a line that is perpendicular to the line whose equation is 2y+3x=1?
Answer:
4x - 6y = 3
Explanation:
To find the slope of the original line, we can put the equation in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. To do this, we can solve for y:
[tex]2y+3x=1[/tex]
Subtract 3x on both sides
[tex]2y=-3x+1[/tex]
Divide by 2
[tex]y=-\frac{3}{2}x+\frac{1}{2}[/tex]
The slope of the original line is [tex]-\frac{3}{2}[/tex]. The negative reciprocal of this is [tex]\frac{2}{3}[/tex] (flip the fraction and change the sign) which becomes the slope of the perpendicular line.
To find the equation of the perpendicular line, we can use the point-slope form of the equation of a line, which is: [tex]y-y1=m(x-x1)[/tex] where x1 and x2 is a point on the line and m is the slope.
We can choose any point on the line; for simplicity, we can choose the y-intercept of the original line, which is (0, 1/2).
[tex]y-\frac{1}{2} = \frac{2}{3}(x-0)\\[/tex]

Vegetables, fruits, flowers, ornamentals, and lawn grassesare examples of horticultural crops and are typically produced on a smaller scale with more intensive management than agronomic crops. Some horticultural crops are grown for aesthetic enjoyment and recreation.
The word horticulture is derived from two Latin words (hortus[garden]+cultura [culture]), and is defined as “the art and science of growing fruits, vegetables, herbs, nuts and ornamental plants (trees, shrubs, flowering plants and turf).
horticulture, the branch of plant agriculturedealing with garden crops, generally fruits, vegetables, and ornamental plants. The word is derived from the Latin hortus, “garden,” and colere, “to cultivate.” As a general term, it covers all forms of garden management, but in ordinary use it refers to intensive commercial production. In terms of scale, horticulture falls between domestic gardening and field agriculture, though all forms of cultivation naturally have close links.

The boiling point is the five words or phrases that most closely relate to one another. Hence, option (4) is right.
What is meant by surface tension?When at rest, liquid surfaces have a tendency to condense into the smallest surface area possible due to surface tension. Sharp blades and insects with densities greater than those of water, like water striders, can float on the water's surface without even partially submerging. Surface tension makes this possible.
The higher attraction of liquid molecules to one another (due to cohesion) than to the molecules in the air is what causes surface tension at liquid-air contacts (due to adhesion).
