Answer:
B. Geothermal refers to heat sources on the Earth’s crust
Explanation:
- The geothermal energy is the heat that is derived from the storing of energy that creates by the earth's temperature and the earth's crust is origin for this type of energy along with the radioactive decay of the elements of the crust.
- <u>Thus said to be earth's internal heat and needs to be trapped as it can get lost during the formation stages. </u>
- The temperature that occurs at the earth's core and the metal zone reaches up to 4000°C and thus the high temperature causes the rocks to melt and give rise to the temperature in the plastic mantle to get activated by the convection currents that reach the surface.
- Some examples of this geothermal energy are those of the hot spring and the rising lava or the magmas.
Answer:
A canal that connected the Hudson River to Lake Erie.

The construction of this channel was something innovative and that generated very positive reactions to the public. First, this was a bold construction that used many innovative concepts, being considered one of the newest wonders in the world. Secondly, this construction would improve the lives of many people, as it would allow a fixed and continuous connection from the northwest to New York, facilitating transportation in a great way.
Answer: Hydroelectricity.
Explanation:
Answer: EVAPORATION.
Explanation: Salinity can be defined as the saltiness or the concentration of salt dissolved in a body of water. Measured in grams of salt divided by the kg of water.
Evaporation increases the salinity of water. Basically, evaporation is the process of converting liquid into gaseous state. In essence, concentration of a solution can be increased by evaporation and since the salinity of water is measured in grams of salt divided by the kg of water, therefore, the lesser the amount of water per salt, the higher the salinity.
