Answer:
Ridge and valley landscapes are created by the<u> tectonic movements of the tectonic plates.</u>
Explanation:
The lithosphere is a rigid outermost shell of the Earth. This lithosphere is broken into<u> tectonic plates.</u> The large scale movements of the tectonic plates result in the formation of topographic features like<u> the mountains, volcanoes, valleys, ridges and oceanic trenches. </u>
Therefore, if the tectonic plates are moving away from each other and create a split, it leads to the formation of a<u> valley</u>. Other environmental factors that can facilitate the formation of a valley are climatic weathering, water, wind erosion etc.
The formation of<u> ridges</u> generally occurs due to tectonic deformation driven by subduction zones, thrust faults, etc. Ridges can also be formed by the tectonic deformation caused by magma present in the deeper layers of the Earth. As, the magma pushes the two plates away, a ridge is formed.
Answer:
It's important to understand that the U.S. we have a "republic" and it's a representative democracy. The citizens have a say in the government, however we have to vote on representatives that have the same ideas as us. Unlike ancient Greece, e.g Athenians, who voted directly on the law without having to go through representatives.
Explanation:
Each year 500 names were chosen from all the citizens of ancient Athens. Those 500 citizens had to actively serve in the government for one year. During that year, they were responsible for making new laws and controlled all parts of the political process. When a new law was proposed, all the citizens of Athens had the opportunity to vote on it. To vote, citizens had to attend the assembly on the day the vote took place. This form of government is called direct democracy.
The United States has a representative democracy. Representative democracy is a government in which citizens vote for representatives who create and change laws that govern the people rather than getting to vote directly on the laws themselves.
Answer:
<u>Thus due to the fact that the sun is so hot and is larger in size as compared to the rest of the plants in the solar system, and presence of earth near the sunalos effect.</u>
Explanation:
- The 93 million miles means 150 million kilometers from the earth but still, the earth gets 100% of the energy it needs from the sun as the diameter of the sun is about 1.39 million kilometers and has a mass of 330,000 times that of Earth.
- Sun has hydrogen 73% and helium 25% and heavier elements, like carbon, neon, and the iron sun is a G type star and sun's heat is transferred from its core by radiation and has a metallicity of 84%.
- The chromosphere of the sun can have coronal temperatures to 2,000,000 K as the solar flare can reach out of this sphere and as a result, the atmosphere of mercury and venus is barren.
- Corpuscular energy from the sun reaches the earth in the abilion of fraction and another phenomenon also known as the northern and southern lights is also produced due to the same impacts of the sun on the outer surface of the earth.
Answer: True
Central America has had difficulty in finding a good political and economic balance following centuries of domination by European nations because the people of Central America were not united. Corruption had been one of the main obstacles to development in Central America and the inability of the government to eradicate corruption resulted in political and economic instability.
