The temperature of the mantle is_____.
- A.
450-775
- B.
870-2200
- C.
4500-5001
- D.
2600-3000
Correct Answer
B. 870-2200Explanation
The temperature of the mantle is believed to range between 870 and 2200 degrees Celsius. This range is based on various scientific studies and observations, including the analysis of volcanic rocks and the behavior of seismic waves passing through the Earth's interior. The mantle is a layer of the Earth located between the crust and the core, and it is composed of solid rock that can deform and flow over long periods of time. The high temperatures in the mantle are primarily due to the heat generated by the decay of radioactive elements and residual heat from the planet's formation.Rate this question:

The Outer core is made up of:
- A.
Liquid metal
- B.
Plasticity
- C.
Solid metal
Correct Answer
A. Liquid metalExplanation
The outer core is made up of liquid metal. This is because the outer core is the layer of the Earth located beneath the mantle and surrounds the inner core. It is composed mainly of iron and nickel, which are both metals that have a high melting point. The intense heat and pressure in the Earth's core cause these metals to exist in a liquid state. This liquid metal is responsible for generating the Earth's magnetic field through a process called the geodynamo.Rate this question:

The outer core's main elements are______ & Nickel
Correct Answer
ironExplanation
The outer core is composed mainly of iron and nickel. These elements are the primary constituents of the outer core, which is the liquid layer surrounding the solid inner core of the Earth. Iron and nickel are both dense and metallic elements that are believed to be present in large quantities in the outer core due to their high melting points. This composition is supported by seismic data and the study of meteorites, which have similar elemental compositions to the Earth's core.Rate this question:

The lithosphere is approximately ____ km thick
Correct Answer
100Explanation
The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle. It is approximately 100 km thick. The lithosphere is divided into tectonic plates, which float on the semi-fluid asthenosphere below. This layer is responsible for the movement and interaction of these plates, leading to various geological phenomena such as earthquakes and volcanic activity.Rate this question:
- 8.
The lithosphere includes the ___ & Upper mantle
Correct Answer
crustExplanation
The lithosphere is the outermost layer of the Earth, consisting of the crust and the uppermost part of the mantle. It is a rigid and solid layer that encompasses the Earth's landmasses and ocean basins. The crust, which is the outermost layer of the lithosphere, is the thinnest and most superficial part of the Earth's structure. Therefore, the correct answer is "crust."Rate this question:
- 9.
The lithosphere is made up of___
- A.
Plates
- B.
Iron
- C.
Nickel
- D.
Plasticity
Correct Answer
A. PlatesExplanation
The lithosphere refers to the rigid outer layer of the Earth, which is divided into several large and small plates. These plates are composed of the Earth's crust and a portion of the upper mantle. They float on the semi-fluid asthenosphere beneath them. The movement of these plates, known as plate tectonics, is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. Therefore, the correct answer is plates.Rate this question:

What layer is composed of solid metal?
- A.
Inner Core
- B.
Outer Core
- C.
Mantle
- D.
Crust
- E.
Moho
Correct Answer
A. Inner CoreExplanation
The inner core is composed of solid metal. This is because it is located at the center of the Earth, where the pressure is extremely high. The pressure is so intense that it prevents the metal from melting, despite the high temperatures. Therefore, the inner core remains in a solid state, primarily made up of iron and nickel.Rate this question:

The asthenosphere is located inside the _____.
Correct Answer
mantleExplanation
The asthenosphere is a layer located inside the mantle. The mantle is the region between the Earth's crust and the core. It is composed of solid rock that is capable of flowing slowly over long periods of time. The asthenosphere specifically refers to the upper part of the mantle, where the rock is partially molten and behaves like a plastic material. This layer plays a crucial role in plate tectonics, as it is responsible for the movement of the Earth's lithospheric plates.Rate this question:
- 12.
The asthenosphere is made up of solid rock that has the property of ____.
- A.
Iron
- B.
Nickel
- C.
Plasticity
Correct Answer
C. PlasticityExplanation
The asthenosphere is made up of solid rock that has the property of plasticity. This means that the rock in the asthenosphere is capable of flowing and deforming under stress, even though it is solid. This property allows the asthenosphere to undergo convection currents, which play a crucial role in plate tectonics and the movement of Earth's lithospheric plates. Plasticity is essential for the asthenosphere to accommodate the movement and interaction of these plates.Rate this question:
-
- 13.
The ______ Is solid due to pressure.
Correct Answer
inner coreExplanation
The inner core is solid due to pressure because it is located at the center of the Earth where it experiences immense pressure from the layers of the Earth above it. This pressure is caused by the weight of the overlying rock and materials. The intense pressure compresses the iron and nickel in the inner core, preventing it from melting despite its high temperature. As a result, the inner core remains in a solid state.Rate this question:
- 14.
Lithosphereic plates move on top of the___
Correct Answer
asthenosphereExplanation
The lithospheric plates move on top of the asthenosphere. The asthenosphere is a semi-fluid layer of the Earth's mantle beneath the lithosphere. It is composed of partially molten rock that allows the rigid lithospheric plates to move and slide on top of it. This movement of the plates is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges. The asthenosphere acts as a lubricating layer that facilitates the plate tectonic movements.Rate this question:

- B.
Iron
- C.
Nickel
- D.
Magnesium
- E.
Helium
Correct Answer(s)
B. Iron
C. NickelExplanation
The outer core of the Earth is primarily composed of iron and nickel. These elements are believed to be in a liquid state due to the high temperatures and pressures found in this region. This composition is supported by seismic data and the study of meteorites, which have similar elemental compositions to the Earth's core. Potassium, magnesium, and helium are not typically found in the outer core and have different roles in other parts of the Earth's structure.Rate this question:

The mantle is made up of ________, _________, iron and magnesium
Correct Answer(s)
silicon and oxygenExplanation
The mantle is composed of silicon and oxygen, as well as iron and magnesium. These elements are the main components of the Earth's mantle, which is the layer located between the crust and the core. Silicon and oxygen form the majority of the mantle's composition, with iron and magnesium also present in smaller amounts. This combination of elements gives the mantle its unique properties and contributes to the overall structure and dynamics of the Earth's interior.Rate this question:

I am a sedimentary rock. I am very coarse grained. I have a brownish color. Who am I?
Correct Answer
conglomerateExplanation
Conglomerate is a sedimentary rock that is characterized by its coarse-grained nature and brownish color. It is composed of rounded fragments and pebbles that are cemented together. The large grain size indicates that the rock was formed from the deposition and compaction of larger particles, such as gravel and pebbles. The brownish color may be due to the presence of iron oxide minerals or organic matter. Therefore, based on the given characteristics, the correct answer is conglomerate.Rate this question:
