Deforestation can represent the impact that colonialism had on the region
Answer: Option A
<u>Explanation:</u>
Colonialism is the colonizing of a country by some other country which was more powerful and had more authority. Colonies are made because the powerful countries search for natural resources, wealth, precious items in their colonies.
These colonies are also a place for raw material or for increasing trade of the finished goods of the country. All this leads to exploitation of the colonies also leading to deforestation where colonies have to cut down their trees and damage the environment for the benefits of the colonists.
Answer:
b. flat rotation curves in spiral galaxies
Explanation:
Dark matter accounts for majority of the matter in the universe (about 85%). It is considered to be composed of subatomic particles which are yet to be discovered. Dark matter cannot be observed because it does not emit light that can be detected. Only its gravitational effect is visible.
Astronomers when calculated the mass of the visible matter and tried to account for the observed speed of stars in the galaxy, there was a mismatch. To understand what caused this mismatch, astronomers gave name to the invisible matter as the Dark Matter.
The expected velocity of stars should decrease away from the near the center of the galaxy but a constant velocity of stars was observed that is a relatively flat rotation curve was obtained.
Thus, flat rotation curves in spiral galaxies in an evidence of Dark Matter.
Answer:
This question is incomplete, because there is no picture, but I attached one, related with the question. The correct answer Trade winds are shown as number 1.
Explanation:
Trade winds and permamnet winds which blow between Tropic of Cancer, Equator and Tropic of Capricorn (which is between 30 degrees N and 30 degrees S.
These wind always flows from Tropics towards the Eqautor, because around the Eqautor is permanent low pressure area, and around the Tropics is permanent high pressure area. Air always flows from high pressure towards low pressure area.
Due to Earth's rotation trade winds curve a little bit, a they become prevailing Northeasterly Trades (in Northern hemisphere) and Southeasterly Trades (in Southern hemisphere). Earth rotates in west-east direction, and that is the reason for their deflection.
Trade winds got their name in the Age of Discovery (14-15 century) when sailing around the world and explorations were very common. Explorers find out that in specific regions exist winds with permanent direction. That was very importnant in the Middle Ages, so explorers always followed their patterns. Term '<em>trade</em>' is actually from Middle English and it means '<em>track</em>'.
