Sometimes, some partly molten material rises towards the Earth's surface because either it gets added to the magma in the due course of the upward movement of magma and the magma doesn't get enough to melt it completely, or the material consists of elements with extremely high melting points.
Explanation: The magma carries molten material from the mantle towards the surface of the Earth. In its course of rising up, sometimes some materials get added to it after it is just about to reach the Earth's surface. Such material doesn't melt completely and reaches the surface in a partly molten form. In other cases, the magma consists of elements with melting points above 1200° Celsius to 1300° Celsius. Such materials sometimes reach the Earth's surface in a partly molten form.The net primary productivity of cultivated land is most similar to the net primary productivity of which ecosystem?
The net primary productivity of cultivated land is most similar to the net primary productivity of the temperate grassland. Temperate grassland is a terrestrial ecosystem whose main plants consist of shrubs or grass. The environment is temperate and it ranges from semi-humid to semi-arid.
The net primary productivity of cultivated land is probably most similar to that of tall-grass prairies or temperate deciduous forests, which have significant natural productivity, unlike the extremes of tropical rainforests or deserts.
The net primary productivity (NPP) of cultivated land can be compared to various natural ecosystems based on their energy accumulation and conversion efficiency. As the table provided does not specify the exact NPP of cultivated land, we must infer based on general knowledge about ecosystems. Typically, cultivated lands have moderate to high NPP due to human management, including the use of fertilizers, irrigation, and crop breeding, to optimize production. Therefore, the NPP of cultivated land might be most similar to ecosystems like tall-grass prairies or temperate deciduous forests, which have substantial natural productivity and are often associated with fertile soils and favorable water availability. Cultivated land's productivity generally would not match that of a tropical rainforest, which has the highest NPP, nor would it be as low as a desert ecosystem.

The rebellion was crushed by the British.
The rebellion was fought in the 1950s.
A) The rebellion began when Kikuyu took land from the Masai.
Explanation:The Mau Mau rebellion is a result of battles fought during the colonial times in Kenya revolting against the colonist settlers. The country was faced with a lot of challenges politically, economically, etc. However, the colonial settlers worsened the situation by enforcing laws that in their favor for land ownership capturing land from the natives.
The revolution began with various attacks against the European settlers that led to damaging their property and they further gained support from Kenyan natives across the country through their uprising movement to gain back the land and eradicate the European settlers.

How is cotton farming harmful to the soil what was done to keep the earth usable?
Cotton plants require large quantities of nutrients and they absorb all the nutrients from the soil, what has been done to have the soil beneficial is cotton farmers ought started crop alternating.
Explanation:Indeed if cotton farmers follow crop rotation because the pesticides and fertilizers do not endure on the plants themselves, they can influence later cotton crops, other food yields an area that may not relate to the cotton farmer at complete.
which is a wave-cut platform?
A)a sand ridge
B)a flat bench like surface
C)a ridge of sand projecting the bay
D)a sandbar
ANSWER:
A wave cut platform is a 'flat bench like surface'.
EXPLANATION:
This a narrow flat area that is found along a shoreline. The area is created because of erosion caused by water that hits the shoreline.A 'wave cut platform' can be easily seen when the tide is low. 'Wave cut platforms' are usually huge areas of 'flat rocks'. These are mostly formed because of the cliff erosion and the rocks are more resistant that undergo weathering but are rarely carried away by water.What is the heaviest element that can be fused in the core of a star?
Answer:
The heaviest element which can be fused in the 'core of a star is iron'.
Explanation:
Throughout a stars lifetime, there is a 'continuous fusion reaction' going on in its core. This reaction is fed by various elements present near the core of the star.These elements can most probably be hydrogen, helium, carbon, oxygen, nickel, and iron. When the star runs out of one elements, it uses the other to continue the fusion reaction going on in its core.Compared with the rest of Brazil, the northeast region has _____.

How does trade and exchange affect groups of people? How does this relate to wealth in Brazil?
Trade and exchange mostly always benefits those nations that engage to it, nevertheless only when it is average to the total national economy. Also, a minority is always hurt by the evolution of trade patterns, and they’ll always ask for protection. In relation with this, Brazil is composed of a only a few wealthy people and a lot of very poor people. This gap among the highest and lowest socials levels is so huge, even though it already decreased during the late 1990s. However, stabilization to the economy, by means of lower inflation levels has likely added more purchasing power to the less fortunate.

Which region of the early universe was most likely to become a galaxy? which region of the early universe was most likely to become a galaxy? a region whose matter density was lower than average a region whose matter density was higher than average a region with an unusual concentration of dark energy?
The answer is : a region with an unusual concentration of dark energy. A region whose dark matter density was higher than average, because gravitational runaway takes regions that are initially denser and makes them the more denser.
Answer:
The region of the 'early universe' whose matter density was higher than the average was most likely to become a 'galaxy'.
Explanation:
For an object to be subjected to gravity, it needs to have a specifically higher density. During the formation of galaxies in the early universe, 'the action of gravity' within and over the dense regions of the universe is believed to have 'played a significant role'. The regions which are found in the universe denser than average were the regions where the 'first galaxies of the universe' were formed.issues such as lack of land and lost resources are examples of this

What do most current climate models suggest will happen to global temperatures by the end of the 21st century?
ANSWER:
Most current climate models suggest that the global temperatures will rise by the end of 21st century.
EXPLANATION:
This will happen because of the global warming being caused by the greenhouse gas emissions. The rising temperatures will change the rate of precipitation which will increase because with more evaporation, the water cycle will become faster. The increased temperatures will also cause ice and snow to melt more resulting in the decrease in the glaciers and ice sheets that float on oceans. The climate will change in an extreme manner meaning that summers and winters will become more severe.When a galaxy is observed moving toward the earth, what visible radiation (as in, which color) will it emit?
Answer:
When a galaxy moves towards the earth, it will emit blue colour light.
Doppler blueshift occurs when the source of light is coming near to its observer. Alternatively, Doppler redshift occurs when the emitter of light moves away from its observer.
Blueshift occurs when wavelength of light decreases. Redshift occurs when wavelength of light increases.
Blueshift makes the colour of the light move from red towards blue.
The shift in wavelength is determined by observing the spectrum with a spectrometer.
