(Q020) Diamonds a. are brought from the mantle to the surface in magma that hardens into kimberlite. b. are found in carrot-shaped structures called pegmatites. c. of industrial quality (non-gem quality) have no use and are usually discarded. d. are exceedingly rare, which is why their price is so high.
Answer:
A. are brought from the mantle to the surface in magma that hardens into kimberlite
Explanation:
Diamonds are brought to the surface from the mantle in a magma that is known as the kimberlite. This kimberlites is rich in gases and it is an igneous rock that has the following minerals,olivine, phlogophite, serpentine etc.
The origination of diamonds in the mantle happens as carbon transformation occurs due to heat and pressure occurs. The kimberlite pipes and what brings the diamonds to the surface
What are the solutions to overcome problems caused by fold mountains?
Answer:
They form when two plates with landmasses on them move towards each other.
The plates push layers of accumulated sediment in the sea into folds between them.
This becomes a fold mountain range.
Most fold mountains continue to grow as the plates constantly move.
Examples: the Himalayas (Asia), Rockies (USA), Andes (South America), Alps (Europe)

(Q017) The age of oceanic crust a. is the same throughout the world's oceans. b. is greatest at the mid-ocean ridge and least farthest from the ridge. c. has been determined by radiometric dating. d. indicates that the oldest oceanic crust is approximately 600 million years old.
Answer:
c. has been determined by radiometric dating
Explanation:
Radiometric dating is a method that is used to determined by the age of rocks as per the age of the oceanic crust the plates near the mid oceanic ridges are the most recent or new. The plates that are located farther away form there ridges are oldest and hence the age of the oceanic crust is not the same in all the places of the world oceans.Can someone please help me with these problems!

Which letter in this diagram represents evaporation?
A
B
C
D
Answer: The Answer is A
Explanation: Because that cycle shows the process of evaporation .
The salt Intrusion is being condensed to water vapour through heat from the sun.
HOPE THIS HELPS!!!!
Evaporation is the process that allows a liquid to change of phase to a gas phase or vapor.
We will see that the correct option is A.
In the image we can see the cycle of water, we know that roughly it works as:
Water liquid.Water evaporates and goes to the clouds.Rain makes the water come down to the Earth.Finally, that water comes again to the larger masses of water.So looking at the image, we can see that the point that represents the evaporation of water is point A, where we have arrows that show the direction that water takes, meaning that it goes from the liquid to the clouds (goes from liquid to gas)

2 List five different environments you know
Answer:
Forests, grasslands, deserts, tundra, freshwater, and marine.
Explanation:
Answer:
Five different environments are the forest, desert, grasslands, freshwater, and mountains.
Explanation:
A forest environment is a complex ecosystem consisting mainly of trees that buffer the earth and support a myriad of life forms. The trees help create a special environment which, in turn, affects the kinds of animals and plants that can exist in the forest. Plants provide habitat to different types of organisms.Desert environments are extremely dry environments that are home to well-adapted plants and animals. The main types of deserts include hot and dry deserts, semi-arid deserts, coastal deserts, and cold deserts.Grassland environments are areas in which the vegetation is dominated by a nearly continuous cover of grasses. Grasslands occur in environments conducive to the growth of this plant cover but not to that of taller plants, particularly trees and shrubs. Freshwater environments are defined as having a low salt concentration — usually less than 1%. Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration (i.e., ocean). There are different types of freshwater regions, such as ponds, lakes, rivers, streams, and wetlands.Mountain environments are made up of complex living organisms in mountainous areas. Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, or tundra.How did Britain's policy of salutary neglect contribute to the Revolutionary War?
ОА.
Because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
O B. Because the colonies did not have de facto independence, they revolted when Britain withdrew military and other aid.
OC. Because the colonies had de facto independence, they revolted when Britain granted other colonies true independence.
OD. Because the colonies felt de facto neglected by Britain, they revolted when it stopped contributing to their economy.
Answer:
A. Because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.
Explanation:
The American Revolutionary War was a war of independence of the United States of America that was fought between the 19th of April, 1775 and 3rd of September, 1783. The war started when the delegates from the thirteen (13) American colonies in Congress (First continental congress) revolted against the Great Britain over their lack of representation in the colonies and refusal to give consent to parliament's taxation such as Stamp Act and Townshend Acts.
Hence, Britain's policy of salutary neglect contributed to the Revolutionary War because the colonies had de facto independence, they revolted when Britain enforced taxes and regulations on them.

Explanation:
La producción primaria y agraria Las actividades primarias
1-¿Cuáles son las actividades primarias? Explique cada una.
Answer:
El sector primario es el sector económico que recibe beneficios de la naturaleza. El sector primario incluye las siguientes industrias: agricultura, caza, apicultura, silvicultura y pesca. Parte del sector primario se utiliza sin procesar, pero la mayor parte es materia prima de empresas del sector secundario. El sector primario a veces incluye la industria minera, pero principalmente las empresas mineras son empresas de otras industrias.
El sector primario fue la primera actividad económica en la historia de la humanidad (recolección y caza). Hasta el comienzo de la revolución industrial, tenía la mayor participación en la economía mundial, pero dentro del sector, la agricultura era la más importante.
En la economía actual, el predominio del sector primario indica que un país o región está rezagado. Este es el caso de la mayoría de los países africanos, donde la mayor parte de la población sigue empleada en la agricultura. Un país donde predomina el sector primario es una sociedad agraria.

If the formula for the area of a polygon is 1/2 (perimeter)(apothem), the area of the hexagon is ___ 3 square units
Answer:
The correct answer would be - 3ab.
Explanation:
Given:
area of polygon = 1/2 (perimeter)(apothem)
let assume the length of a side of the hexagon = x
The length of the apothem = a
Formula used:
the perimeter of polygon = number of sides*length of the side
for hexagon = 6*x .....1
Solution:
As the formula for the area of a polygon is given, and the hexagon is a polygon as it has six sides then the area then,
Area of hexagon = (1/2)* (6x) (a)
= 6ax/2
= 3ax
put the value of a and x and get the numeric value.
