Mafic materials are usually dark in color and have relatively high specific gravities grater than 3.0 Felsic materials are usual at lighter in color and have specific gravities less than 3.0
T,Q,R,S
Reasoning: T is hit with the most pressure then Q then R and S
Answer:
Three factors are used.
The availability of sunlight.
The distance from shore and
The water depth.
Explanation:
<u>Availability of Sunlight
</u>
The photic zone is the upper part of the ocean into which sunlight penetrates.
<u>Distance from Shore
</u>
The intertidal zone is the strip of land where the land and ocean meet and overlap, or the zone between high and low tides.
The neritic zone is the marine-life zone that extends from the low-tide line out to the shelf break.
The oceanic zone is the marine-life zone beyond the continental shelf.
<u>Water Depth</u>
The pelagic zone is open zone of any depth. Animals in this zone swim or float freely.
The benthic zone is the marine-life zone that includes any sea-bottom surface regardless of its distance from shore.
The abyssal zone is a subdivision of the benthic zone characterized by extremely high pressures, low temperatures, low oxygen, few nutrients, and no sunlight
Answer:
Renewable energy: solar radiation
Farm example: Farm located in Heggelbach, Germany
Explanation:
Solar radiation is one of the most used types of renewable energy. It proportionates light during the whole day (even during the cloudy days), which is received by solar photovoltaic panels. These photovoltaic panels are formed by solar cells that turn the solar light (photons) into electricity (electrons) through the photoelectrical process. Certain materials are capable of absorbing photons and releasing electrons, generating by this movement, electric current.
Solar energy is being used in many places to avoid using fossil fuels as energy sources and replace them. Specifically, in farms, this energy is used for equipment operation and machinery use.
Even the combination of solar panels and agriculture is taking place in the same land area or parcel. In the same place where solar panels are installed, and under them, vegetables are being grown. The advantage for certain vegetable species is that panels protect from excessive radiation or other adverse climatic conditions.
<u>Example:</u>
In 2018 in Heggelbach - Germany- a five meters structure of solar panels was installed on a farm. Under them, different crops were grown. The production under the photovoltaic system was highly superior to the traditional one. The efficiency of land use increased by 186% per hectare with the agro-photovoltaic system.
