Explanation:
Energy can be defined as the ability (capacity) to do work. The various forms of energy are solar energy, electrical energy, chemical energy, thermal energy, wind energy, nuclear energy etc.
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
Some of the terminologies associated with energy includes the following;
1. Fuel cell: produces electrical energy chemically. It is a technology that operates just like batteries but do not need to be recharged since it doesn't run down. Also, it comprises of two (2) electrodes which are: positive electrode (cathode) and negative electrode (anode), with an electrolyte embedded in between them.
2. Alternative energy: energy sources that are still in development. These includes energy source other than fossil fuels. Some examples are petroleum, diesel and coal.
3. Energy conservation: includes lifestyle changes. It involves energy saving actions in order to reduce the level of energy consumption such as daylight savings, energy saving bulbs, etc.
4. Ocean thermal energy conversion (OTEC): produces electrical energy using the temperature difference between two layers of water.
5. Energy efficiency: percentage of energy that does useful work. It determines the amount of work that can be done at a particular time.
Answer:
Devonian, Silurian, Ordovician
Explanation:
The geologic age sequence of the surface bedrock from Ithaca to water town is Devonian, Silurian, Ordovician.
A bedrock is the hard, solid rock under the material surface of soil or grovel. The material that is on top of the material layer is mostly unconsolidated rock usually consisting of loose particles. Bedrocks have the capacity to expand hundreds of meters. They can even be found extended all the way to the earths crust.
