A. Describe the roles of mechanical and chemical weathering in the formation of the sediments that are eventually incorporated i
Serhud [2]

Answer:

As explained below.

Explanation:

  • Sedimentary rocks that are formed due to the accumulation of sediments that are derived from the deposition of small particles and their cementation of minerals and organic particles in the seafloor by the impact of various geological and earth processes like the wind, water, and glacier erosion.  
  • Earth's crust is covered by 73% of sedimentary rocks and about 8% of the total crustal surface. Based on their formation, these rocks are thus classified as  Siliciclastic, Carbonate, Evaporite, Iron-rich, and Phosphatic sedimentary rocks.
  • The color of these rocks is always determined by the iron and oxide contents, their size texture is a result of the density and permeability of the rocks like in the case of sandstone and limestone.
  • The relationship between the plate tectonics and the earthquakes is explained through the seismic waves that travel; through the three-layer of the earth from core to mantle to crust.
  • Earthquakes are directly related to plate boundaries as these are areas where these waves come out in the form of shocks and shaking of lands thus we expect of seeing three types of boundaries as  Convergent, Divergent and Transform.

What is a FREE TRADE area?
kipiarov [429]

Answer:

a group of countries that have agreed to eliminate tariffs and trade barriers

Explanation:

    Free trade area is a trade agreement made between countries whose main intention is to increase trade relations between them by eliminating tariffs and quotas on the import and export of goods and services.

    The Free Trade Area is considered one of the intermediate phases for the formation of an economic bloc.

    It is noteworthy that it is not a customs union, because there is no common trade policy between countries, not even the establishment of external tariffs valid for all.

    These agreements are governed by the WTO (World Trade Organization) or by agreements between the member countries themselves.

What environmental impacts are caused by both surface mining and underground mining? Select the two correct answers.
UkoKoshka [18]

Answer:

B. local water contamination

D. destruction of ecosystems

Explanation:

The mining, be it a surface one or underground one, has several negative impacts on the surrounding area. Two common negative impacts of both types of mining are contamination of the local waters, as well as the destruction of ecosystems.

The waters get heavily polluted with toxic chemicals pretty much always ad everywhere where there is mining. The main reason for this is that the nus-products from the mining are released into the waters. This causes high level pollution of the waters, thus making it not good for anything, and the aquatic life in the waters dies out rapidly.

The fact that the waters are heavily polluted means that everything that comes in touch with them becomes heavily polluted as well. Also, apart from releasing chemicals in the waters, the mining requires space, so the area is cleared out, and after that lot of toxic material is disposed on it. The majority of the plants can sustain that, so they die out, and since they are the basis of the ecosystems, the animals die out as well.

If you could drill from the outer surface of Earth all the way to the center, you would pass through the major divisions of Eart
natima [27]

Answer:

- crust

- mantle

- core

Explanation:

The Earth is a planet that is divided into three major divisions, or layers. The top layer is the crust, which is brittle solid, and it is also the thinnest ones of the all. The second layer is the mantle, which is a layer that has higher temperature and pressure, composed mostly of molten rock, and being responsible for the tectonic movement on the crust above. The third, deepest layer, is the core. The core is the hottest and has the highest pressure. It is the layer that is responsible for the magnetic field of the planet.
