Questions and Answers
- 1.
Geothermal energy is created from water that is super heated by ______ within the earth’s crust.
Explanation
Geothermal energy is created from water that is super heated by magma within the earth's crust. Magma is a molten rock found beneath the Earth's surface. As magma rises towards the surface, it heats the surrounding rocks and water. This superheated water can be tapped into and used to generate electricity or for heating purposes. Therefore, magma plays a crucial role in the creation of geothermal energy.Rate this question:

Thermal means _______.
Explanation
Thermal means heat. The term "thermal" is used to describe anything related to heat or temperature. It can refer to the transfer of heat, the measurement of temperature, or the properties of materials at different temperatures. In this context, "thermal" is synonymous with "heat".Rate this question:
- 4.
The deeper one travels into the earth, the cooler the temperature becomes.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
As one travels deeper into the earth, the temperature actually increases rather than decreases. This is due to the geothermal gradient, which is the rate at which the temperature increases with depth in the Earth's interior. The deeper one goes, the higher the pressure, and with increased pressure comes increased temperature. Therefore, the statement that the temperature becomes cooler as one travels deeper into the earth is incorrect.Rate this question:

_________ causes heat and magma to rise through the earth, sometimes breaching the earth’s crust.
Correct Answer
ConvectionExplanation
Convection is the process that causes heat and magma to rise through the earth, sometimes breaching the earth's crust. In convection, the hotter material rises while the cooler material sinks, creating a circular motion. This circular motion transfers heat and energy, causing the movement of magma and the upward movement of heat towards the surface. As the magma rises, it can breach the earth's crust, leading to volcanic activity and the formation of new landforms.Rate this question:

Trapped sub-terrestrial pockets of heat and steam are known as geothermal _________.
Correct Answer
reservoirsExplanation
Geothermal reservoirs are sub-terrestrial pockets of heat and steam that are trapped underground. These reservoirs contain hot water and steam that can be harnessed to generate electricity or for direct use in heating and cooling systems. They are formed when heat from the Earth's core is transferred to the surrounding rocks and water, creating a reservoir of high-temperature fluids. The heat and steam in these reservoirs can be accessed through wells and used as a renewable energy source.Rate this question:
- 7.
Cracks in the earth’s surface are known as _______.
Correct Answer
fissuresExplanation
Cracks in the earth's surface are known as fissures. Fissures are narrow openings or cracks that can occur in rocks or the earth's crust. These cracks can be caused by various geological processes such as tectonic plate movements, volcanic activity, or erosion. Fissures can range in size from small, hairline cracks to large, deep crevices. They can have significant impacts on the landscape and can also serve as pathways for the movement of water, magma, or gases.Rate this question:

- 10.
Because the water cycle is non-ending, geothermal energy is considered a form of __________ energy.
Correct Answer
renewableExplanation
Geothermal energy is considered a form of renewable energy because it is derived from the heat generated within the Earth's core, which is constantly replenished by the natural processes of radioactive decay and residual heat from the planet's formation. This means that geothermal energy is virtually inexhaustible and can be continuously utilized without depleting its source. Therefore, it falls under the category of renewable energy sources that can be harnessed for various purposes.Rate this question:
- 11.
The eastern region of the United States is an excellent source of geothermal energy.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement is false because the eastern region of the United States is not an excellent source of geothermal energy. Geothermal energy is typically found in areas with high levels of volcanic activity or tectonic plate boundaries, which are more common in western regions like California and Nevada. The eastern region of the United States does not have the same geothermal resources, making it a poor source of geothermal energy.Rate this question:

The four layers of the earth are the ______, the _______, the _______ core, and the ______ core.
Correct Answer
crust mantle inner outer
crust mantle outer inner
mantle crust inner outer
mantle crust outer innerExplanation
The correct answer is "crust mantle inner outer, crust mantle outer inner, mantle crust inner outer, mantle crust outer inner". This answer is correct because it lists all the four layers of the earth in different arrangements. The crust is the outermost layer, followed by the mantle, which is further divided into the inner and outer layers. The arrangement of the layers can vary, so all the possible combinations are included in the answer.Rate this question:
- 17.
The mantle of the earth is composed of semi-molten rock.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The mantle of the earth is composed of semi-molten rock because it lies between the crust and the core. It is made up of solid rock that is under high pressure and temperature, causing it to become partially molten. This semi-molten rock is responsible for the movement of tectonic plates and the occurrence of volcanic activity.Rate this question:

- 18.
The _____ core of the earth is solid.
Correct Answer
innerExplanation
The inner core of the earth is solid because it is composed primarily of iron and nickel, which are known to be solid at the extreme pressures and temperatures found at the earth's core. The solid inner core is surrounded by a liquid outer core, and together they create the earth's magnetic field.Rate this question:
- 19.
The _______ core of the earth is liquid.
Correct Answer
outerExplanation
The outer core of the earth is liquid because it is composed of molten iron and nickel. This layer is located beneath the earth's mantle and surrounds the solid inner core. The high temperatures and pressure in the outer core cause the metals to be in a liquid state. This liquid outer core is responsible for generating the earth's magnetic field through the movement of the molten metals.Rate this question:
