When plant material becomes compacted and concentrated over time, coals begin to form bituminous  is a black rock that is shiny, but not metallic in appearance Therefore the correct option is A.

This process is known as coalification and results in the formation of black, shiny rocks that are not metallic in appearance. Coal typically appears dark brown to black in color with a glossy or dull sheen. Coal usually has a soft surface to the touch and can be crumbled easily between the fingers, although there are also coals that are hard and

dense. Coal is considered a combustible organic rock, and when burned it gives off carbon dioxide, water vapor, sulfur dioxide, nitrogen oxide, hydrogen sulfide, mercury and other pollutants into the atmosphere. Coal power plants generate most of their electricity by burning this fossil fuel which results in increased air pollution.

Hence the correct option is A.

Answer:A True/Top soil contains an A horizon above a C horizon, but a sub

The correct option is A True

Topsoil is also called as A horizon. A horizon is the layer which is beneath the O horizon and above the E horizon. Topsoil is predominantly made up of humus and minerals. Humus is the organic matter formed due to the decomposition of dead plants and animals.

A mollic soil contains an A horizon above a C horizon, but an argillic soil contains a B horizon. So, the correct answer is "mollic soil, argillic soil."

A soil horizon is a horizontal layer that is parallel to the soil surface and distinctive in its physical, chemical, and biological characteristics. In general, soils consist of three layers: A horizon (topsoil), B horizon (subsoil), and C horizon (parent material).The mollic soil is a thick, dark soil with a high organic matter content and is soft and crumbly. The A horizon is dark in color due to the presence of organic matter and humus. The C horizon is less fertile and has a pale color, indicating that it has been weathered.The argillic soil, on the other hand, is a clay-rich soil with a low permeability. The B horizon contains the accumulation of clay and mineral materials that have leached from the overlying A horizon, which is rich in organic matter and nutrients. The argillic horizon is rich in clay and other mineral nutrients that have been leached from the upper layers of the soil and can be used for crops.

about tectonic plates and earthquakes in East Asia.

1. Identify the relevant tectonic plates: In East Asia, the key tectonic plates involved are the Pacific Plate, the Philippine Sea Plate (not the "Preppine Plate"), the Indo-Australian Plate, and the Eurasian Plate.

2. Understand plate interactions: The Pacific Plate and the Philippine Sea Plate are both converging with the Eurasian Plate, leading to subduction zones, which are areas where one plate slides beneath another. The Indo-Australian Plate is also converging with the Eurasian Plate, resulting in the formation of the Himalayan mountain range.

3. Examine the locations of the countries mentioned:
Japan is situated at the junction of the Pacific Plate, the Philippine Sea Plate, and the Eurasian Plate, which results in frequent earthquakes and volcanic activity.
Taiwan lies at the boundary between the Philippine Sea Plate and the Eurasian Plate, making it susceptible to earthquakes as well.
North Korea, South Korea, and China are located on the Eurasian Plate. They experience occasional earthquakes due to their proximity to plate boundaries and fault lines.
Note that the North American Plate is not relevant to East Asia, as it pertains to a different geographical region.

4. Analyze data on earthquakes: By examining seismic data, such as the magnitude and frequency of earthquakes in each of the mentioned countries, you can better understand the impacts of tectonic activity in East Asia. For example, Japan experiences a higher frequency of earthquakes and more severe impacts due to its location on multiple plate boundaries.

In conclusion, understanding the tectonic plate interactions and locations of countries in East Asia helps us analyze and predict the occurrence of earthquakes in this region.

The Earth’s mantle is made up of Tectonic plates that are forever moving as the Earth cools down. This happens over billions of years, and one of the most notable ones is around the Pacific rim where Earthquakes, (seismic activity) happens quite often

The Rift Valley in Ethiopia lies along the edge of the African Tectonic Plate, and continues down through parts of Somalia and into Kenya.

Just recently a rift opened up in Kenya, which seismologists seem to think is the pre-cursor of a major tectonic plate movement, splitting apart a part of Africa, which could include Ethiopia.

The Earth's core is composed of primarily molten iron and nickel. Currents in this core are responsible for generating the Earth's magnetic field.

The Earth's core is made up of molten iron and nickel. Its outermost layer is the outer core, which is primarily liquid and about 2,300 kilometers thick. The inner core, on the other hand, is mostly solid, with a diameter of about 1,220 kilometers.What is the function of currents in the Earth's core?The Earth's magnetic field is generated by currents in the Earth's core.

These currents are generated as a result of the movement of molten metals in the Earth's core, such as iron and nickel. These currents, in turn, generate a magnetic field that is essential for the survival of life on Earth. The Earth's magnetic field protects the planet from harmful solar winds, which could cause damage to the planet's atmosphere and, eventually, make the planet uninhabitable.

Question 1:

The Earth is divided into the inner and outer core, mantle, asthenosphere, and the lithosphere.

The lithosphere contains the upper parts of the mantle and the crust, and is broken into pieces called tectonic plates that move, collide and slide apart over time.

Tectonic plates move when partially molten rock in the asthenosphere flows with hot material rising and cooler material sinking. Molten rock in the mantle heats and rises to the upper mantle and asthenosphere, eventually causing it to cool and sink down with convection currents. The process repeats.

Question 2:

Evidence/explanation: Geologic occurences such as earthquakes, volcanoes,  mountain ranges, and valleys occur near faults, meaning that they occur near plate boundaries. This suggests that there may be some movement within tectonic plates that can be linked to these occurences.

The minimum possible lens diameter you would need in order to resolve two stars depends on the angular resolution of the lens, which is determined by its diameter.

To calculate the angular resolution, you can use the formula:
Angular Resolution = 1.22 * (wavelength / diameter)
where wavelength is the wavelength of light and diameter is the lens diameter. To resolve two stars, you need the angular resolution to be smaller than the angular separation between the two stars. If the angular separation is given, you can use the formula above to calculate the minimum lens diameter needed. Please provide the angular separation or any additional information for a more specific answer.

The most explosive volcanoes (aside from the super volcanoes) tend to be found at subduction plate boundaries. What is a Volcano? A volcano is an opening on the earth's surface where molten rock, ash, and gas escape.

It is formed by a volcanic eruption that occurs when magma and other volcanic materials are expelled from a volcanic vent. Volcanoes can be found in various places, including mid-ocean ridges, divergent plate boundaries, convergent plate boundaries, and hotspots. What are Explosive Volcanoes? Explosive volcanoes are a type of volcano that releases a large amount of explosive energy during an eruption. They have a tendency to build up a large amount of gas before erupting, which causes them to explode violently when the pressure becomes too great.

As a result, explosive volcanoes are far more dangerous than their more passive counterparts. Subduction plate boundaries and explosive volcanoes The most explosive volcanoes (aside from the super volcanoes) tend to be found at subduction plate boundaries. Subduction occurs when two tectonic plates converge, with one plate sliding beneath the other, and is responsible for some of the most destructive earthquakes and tsunamis in history. Because of the extreme heat and pressure at subduction plate boundaries, magma is more viscous and gas-rich than in other areas, which is why explosive eruptions are more common.
