Answer:
The scratch test (also known as Mohs Hardness scale) is a way you can test a mineral or stones for its endurance. The minerals you test are scratched by a penny and are measured on a scale of 1-10 on how durable they are. Stones such as quartz have a much stronger endurance to a scratch in the test than marble because of quartzes makeup. Another way to differentiate between the two would be to look at the mineral’s luster. The luster of a mineral is the way the light bounces off of its surface. There are different lusters that different minerals give off. There are two major types of lusters and they are Metallic or nonmetallic. A metallic luster is typically shiny while a nonmetallic luster can have many different types like musty or solid. Because quartz is a quartz it will be metallic because it is shiny while marble will be nonmetallic because it does not reflect light.

Which of the following scenarios are examples of positive-feedback mechanism? Check all that are correct
Answer: Deforestation near the Sahara Desert causes the soil to be exposed. Exposed soil evaporates moisture more readily. Insufficient moisture leads to the death of trees.
A warmer atmosphere causes more evaporation. Water vapor is a greenhouse gas, so this increases the temperature.
Warmer temperatures cause snow to melt. This makes the ground darker, allowing more solar radiation to be absorbed. The warmer ground warms the atmosphere.
Explanation:
Positive feedback mechanism refers to, the changes in a system, which induces further changes. It exists in an environment that leads to the rise in the causative effect of the environment which can change the precipitation, temperature, precipitation and other climatic conditions of the area
Therefore, the examples of positive-feedback mechanism include:
• Deforestation near the Sahara Desert causes the soil to be exposed. Exposed soil evaporates moisture more readily. Insufficient moisture leads to the death of trees.
• A warmer atmosphere causes more evaporation. Water vapor is a greenhouse gas, so this increases the temperature.
• Warmer temperatures cause snow to melt. This makes the ground darker, allowing more solar radiation to be absorbed. The warmer ground warms the atmosphere.

The Sahara Desert in northern Africa is the largest region in the world having the BWh climate. Name another desert in each of the northern and southern hemispheres having the BWh climate.
Southern Hemisphere:
Northern Hemisphere:
Answer:
Northern Hemisphere: Thar desert
Southern Hemisphere: Great Australian desert
Explanation:
The BWh climate is a desert climate. It is a hot and arid climate o the deserts, as classified by the Köppen climate classification of BWh and BWk. The BWh zone falls on the hot and arid regions.
One desert in the Northern hemisphere which contains BWh climate is Thar desert in India. It is a very hot desert with very sandy and rocky surfaces.
One desert in the Southern hemisphere having BWh climate is the great Australian desert. It is a sandy desert with very less precipitation.

8. Son las actividades que consisten en la transformación de la materia prima en productos elaborados o manufacturados.
Answer:
Actividades industriales.
Explanation:
La industria es la parte de la economía que produce bienes y proporciona servicios, a partir de la modificación de las materias primas obtenidas de la naturaleza.
La industria se puede dividir en cuatro partes. La primera parte son las industrias donde los recursos naturales se convierten en productos como la minería, la tala y la agricultura. La segunda parte son las industrias en las que las materias primas se convierten en productos, como la automoción y la siderurgia. La tercera parte son las industrias de servicios como el comercio y la banca. La cuarta parte es la investigación, el diseño y el desarrollo que pueden conducir al cambio y al progreso tecnológico. Los países en desarrollo suelen tener economías basadas más en la primera y segunda partes, mientras que en los países industrializados se pone más énfasis en la tercera y cuarta partes que en los países en desarrollo.
PLEASE HELP ME ANSWER THIS…thank you
Briefly explain why there was a split in Islam that resulted in the creation of the two different sects.
Answer: It is not realy a "split". That would imply two relatively large groups. The fact is that at least 85% of those who call themselves Muslim are all from one group. They are the people who follow the Qur'an and the example of Prophet Muhammad (peace be upon him). They are called 'sunni' Muslims, by some people. In fact, they are simply true Muslims.
The other 15% are all deviant sects that have corrupted the true, original teachings. Anyone who studies Islam can see how the other groups have changed the original message.
Shiites, Ahmadiyyah, Alawi, Ismaili, Druze are some names of deviant groups.
In fact, Muhammad said that there would be such deviants; and he condemned their teachings as leading away from God. He said that the only rightly-guided group would be the one that stuck to the Qur'an and to his example. We thank God that it is the clear majority.
For an understanding of why the Shiite sect developed, you can go to Wikipedia for a detailed explanation. For examples of how they have gone astray from the healthy and true religion, you can go to You Tube and search: Real Shiah Faces.

Answer:
D
Explanation:
In the Layers panel, turn on Borders and Labels and also Gallery > Volcanoes, then double-click on the Problem 7 placemark. Divergent boundaries often begin as triple junctions composed of three rift "arms" at ~120° apart (which may or may not evolve into divergent boundaries). Knowing that rifts (red lines) generally open perpendicular to the rift (or sub-parallel to the light blue transform faults), which of the statements below about this area is incorrect?
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Answer:
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Explanation:
Many crust plates move over the mantle. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types: Divergent, Convergent, and Transforming.
Divergent boundary: Occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. New crust is created by the molten materials rising from the mantle. The two plates at each side of the rift separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom, which separates the plates. The divergence direction is transversal to the rift orientation. Old plates get separated, and the new crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction. CORRECT → The diverging direction is perpendicular to the rift orientation.
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction. CORRECT
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction. CORRECT.
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast ⇒ INCORRECT. The collision between plates creates volcanic arches and continental arches. This process belongs to the convergent boundaries, in which two oceanic plates collide, or one oceanic plate crushes with a continental one.
explain in your own words the three mechanisms that cause air to be displaced into the atmosphere
Answer:
orographic, convectional and cyclonic lifting
Explanation:
orographic is when air mass is forced from lower to higher elevation. convectional lifting is warming up parcel of air at the surface of the earth by conduction. cyclonic lifting is lifting of air mass due to differences in pressure this is when cold air meets warm air.
The three mechanisms that cause air to be displaced into the atmosphere are orographic, convectional, and cyclonic lifting. This is further explained below.
What is air displacement?Generally, Air displacement is simply defined as plethysmography a well-known and scientifically confirmed method of measuring human body composition.
In conclusion, orographic, convectional, and cyclonic lifting affect air displacement now try to rephrase them to aid your essay.
