Earth Science Quiz 4 Energy Resources Flashcards
_____ is a capacity to do work. It can be changed from one to another but it can neither be created nor be destroyed.
Energy
An ______ _______ is something that can produce heat, power life, move objects, or produce electricity.
Energy Resources
What are the two types of energy?
Potential Energy and Kinetic Energy
Type of Energy. It is stored energy that depends upon the relative position of various parts of a system.
Potential Energy
Type of Energy. It is the energy an object has because of its motion.
Kinetic Energy
What are the two main types of energy resources?
Renewable and Non-Renewable Sources of Energy
Type of Energy Resource. These energy sources are produced in nature and are NON-exhaustible.
Renewable Energy Source
5 examples of renewable sources of energy:
- Solar Energy
- Hydro Energy
- Geothermal Energy
- Wind Energy
- Tidal Energy
Type of Energy Resource. These energy sources were formed long ago and are accumulated in nature but are exhausted easily. These CANNOT be replaced.
Non-Renewable Energy Resource
These are examples of NR resources, it is also sources of energy from the deposits of plants and animals, buried thousands of years ago. It is also found in the earth’s crust and contain carbon and hydrogen.
Fossil Fuels
Fossil Fuel explained separately.
Fossil - Remains or traces of prehistoric life.
Fuels - Sources of energy.
What are the three types of fossil fuels?
Coal, Oil, Natural Gas
It is a hard, black-colored sedimentary rock. The largest source of energy for generating electricity in the world.
Coal
How is coal formed?
It is formed when dead plant matter submerged in swamp environments and is subjected to the geological forces of heat and pressure over hundreds or millions of years.
The major types of coal in order:
Peat –> Lignite –> Subbituminous –> Bituminous –> Anthracite
It is an organic material formed from the incomplete decomposition of plant matter under anaerobic conditions.
Peat
This is also known as crude oil or petroleum. It is very precious, and rare and its wide range of uses in many industries.
Oil
This is a gas that is clean and non-toxic type of fossil fuel. No color, no odor, and can be easily transferred through pipelines. Often found near oil deposits.
Natural Gas
Renewable Energy Resources. Heat derived within the sub-surface of the earth. It is a known type of renewable energy obtained from the earth’s core.
Geothermal Energy
The three types of geothermal heat pump:
Dry Steam Plants, Flash Steam Plants, Binary Cycle Plants
Geothermal Heat Pump. Hot steam is piped directly from geothermal reservoirs into generators. The steam spins turbines to generate electricity.
Dry Steam Plants
Geothermal Heat Pump. Water that’s between 300 nd 700 degrees fahrenheit is brought up through a well.
Flash Steam Plants
Geothermal Heat Pump. Moderately hot geothermal water is passed through a heat exchanger, where its heat is transferred to a liquid that boils at a lower temperature than water.
Binary Cycle Plants
Renewable Energy Resources. It refers to the conversion of energy from flowing water into electricity. Considered as such because the water cycle is constantly renewed by the sun.
Hydropower Energy
Three types of hydropower facilities:
Impoundment, Diversion, and Pumped Storage.
Hydropower Facilities. These are the most common technology which uses a dam to create a large reservoir of water. Electricity is made when water passes through turbines in the dam.
Impoundment Facilities.
Hydropower Facilities. These rely more on natural water flow rates, diverting just a portion of river water through turbines….
Run-Of-River Facilities
Type of Dams. ____________ are installed to raise the water level of a body of water to allow the water to be redirected.
Diversion Dams
Hydropower Facilities. It has a second reservoir below the dam. Water can be pumped from the lower reservoir to the upper reservoir, storing energy for use at a later time.
Pumped Storage Facilities
A _____ is a barrier that restricts or stops the flow of water, helps suppress floods, as well as providing irrigations.. etc.
Dam
Seven types of dams:
Diversion, Buttress, Embankment, Cofferdam, Storage, Detention, Gravity Dam
Types of Dams. To divert water. They provide pressure to push water into ditches, canals, or other areas used for conveyance.
Diversion Dam
Types of Dams. Takes many forms, but all consists of a sloping deck supported by intervals of ________. These dam include Multiple Arch Type, Massive Head Type, and Deck Type. Use less concrete but are not cheaper.
Buttress Dam
Types of Dams. It is a large, artificial dam that is constructed with natural excavated or industrial waste materials.
Embankment Dam
Types of Dams. It is a temporary, portable dam used for a variety of projects including bridge repair, shoreline restorations, …. etc. It is used to CLOSE OFF some or all of a construction area.
Cofferdam
Types of Dams. These are not mean to divert or keep water out, but to keep water IN.
Storage Dam
Types of Dams. These are specifically constructed for flood control by retarding flow downstream, helping reduce flash floods.
Detention Dam
Types of Dams. It is a massive, man-made concrete dam designed to hold LARGE volume of water. It is also used to block rivers in wide valleys and must be built on a strong foundation of bedrock.
Gravity Dam
