There are many different alternative energy sources including:
1–Tidal. 2–Wind. 3–Solar. 4–Waterfall.
Match the Type of alternative energy you would most likely find in each region.
Alta. N.S. B.C. Ont.
Wind energy is one of the fastest-growing renewable energy sources after a number of countries have turned to the technology in an effort to reduce their emissions.
The process involves using wind to produce electricity through the use of the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems.
[tex] \\ [/tex]
2. Solar energy :-Solar energy involves converting energy from the sun into thermal or electrical energy using one of the cleanest and most abundant renewable energy sources.
Alongside wind, solar photovoltaic (PV) is the most established of the low-carbon energy technologies and, as it grows in scale, the costs of development are coming down.
[tex] \\ [/tex]
3. Hydro energy :-Hydroelectricity is produced by harnessing the gravitational force of flowing water. The technology is broadly classified into four categories – conventional (dams), pumped-storage, run-of-the-river and offshore marine (tidal).
Compared to fossil fuel-powered energy plants, hydropower plants emit fewer greenhouse gases – but the construction of the plants and dams requires huge investment.
[tex] \\ [/tex]
4. Biomass energy :-A collective term for all plant and animal material, biomass can take many forms – from plants and wood, to animal and agricultural waste.
In power generation it is commonly used as wood pellets that are harvested from forests and burned to release energy.
[tex] \\ [/tex]
5. Tidal energy :-Tidal energy is generated from converting energy from the force tides into power and its production is considered more predictable compared to wind energy and solar power.
Although the world’s first large-scale plant of its type became operational in 1966, tidal power is still not widely used.

the greek island of santorini has no rivers, and freshwater is hard to find, what do people from santorini do to get fresh water?
Answer:
Desalination Rain water stored in cisternsRecyclingExplanation:
Santorini is a very beautiful island in Greece that consistently ranks amongst the most beautiful places in the world.
They have a water shortage problem in the island and have resorted to investing in desalination plants in the island to make ocean water safe to use.
They also store rainwater in cisterns which are large waterproof receptacles that can hold thousands of cubic meters of water at their maximum.
Finally the people are very conscious of using water in the island such that they manage the water effectively. They reuse when they need to and recycle water as much as they can.
what is the difference between the total fertility rate and the rate of natural increase
Answer:
See explanation.
Explanation:
Put simply, natural increase is the difference between the numbers of births and deaths in a population; the rate of natural increase is the difference between the birthrate and the death rate
The rate of population growth is the rate of natural increase combined with the effects of migration. Thus a high rate of natural increase can be offset by a large net out-migration, and a low rate of natural increase can be countered by a high level of net in-migration.
Vào ngày hạ chí ánh sáng mặt trời chiều vuông góc ở chí tuyến bắc, tại sao ngày đó lại chưa phải là ngày nón nhất trong năm ở nửa cầu bắc
Answer:
Due to time required for warmup of land and water.
Explanation:
The hottest day of the year in the northern hemisphere don't fall on the summer solstice i.e. June 21, because the ground and water in the Northern Hemisphere needs time to warm up. It takes 3 weeks or one month to warm up the land and water, once it warm up the hottest day of the year started. so the hottest day of the year in the northern hemisphere comes in the month of July.
In my book there was a statement about agriculture: fields being SMALLER due to HIGHER population density. Shouldn't the fields be bigger BECAUSE there's more people?
Answer:
Fields should be bigger to feed more people, but they are smaller because people live on those lands.
Explanation:
A higher population density means that there are more people in an area. As there are more people, there is not enough space for all of them to live in the city, so new cities and towns emerge occupying the field's lands used for cattle raising and agriculture. There should be larger fields to feed all the population, but they become smaller because parts of them are now populated.

observa las siguientes imágenes y escribe como dañan el ambiente
Answer:
Desertificación.
Explicación:
La quema de combustibles en industrias y vehículos produce gas dióxido de carbono en una gran cantidad que contamina el aire. Este gas de dióxido de carbono es un gas de efecto invernadero que se acumula en la atmósfera y bloquea la radiación solar que va al espacio después de la refección, lo que provoca un aumento de la temperatura de la tierra y una condición de sequía que conduce a la desertificación. Debido a esta desertificación, la vegetación se elimina por falta de agua suficiente.

Discuss TWO measures that have been implemented at the national level of MOST countries to ensure the sustainability of coral reefs . Use examples to support your answer .
Answer:
Lower the emission of carbondioxide gas and planting more trees.
Explanation:
Lower the emission of carbondioxide gas and planting more trees are the two measures that have been implemented at the national level of countries to ensure the sustainability of coral reefs. Carbondioxide emission is the main reason for the destruction of coral reefs because more carbondioxide emission causes decrease the pH level of ocean. This acidic water of ocean damaged the skeleton of coral reefs and as a result thousands of organisms lost their habitat.

Which statement about Earth's layers is true? A. They all consist of liquid rock. B. They each vary in size and temperature. C. They are all under an equal amount of pressure. D. They will soon combine, forming
Answer:
I believe that the answer is B
Explanation:
Answer:
B. They each vary in size and temperature.
Explanation:
Earth's layers vary vastly in terms of temperature, the core being the hottest, and the crust being the coolest. This is the result of the immense pressure, literally the weight of the world, that is forced towards Earth's core by gravity.
The size of these layers varies greatly as well. The crust, in comparison to all other layers, is extremely thin, making up only around 15% of Earth, while the mantle makes up around 84% for comparison.

Differentiate between slope decline and slope retreat
Answer:
The difference between the given topics is described below.
Explanation:
Slope decline:
The decline has been characterized as anything being rejected, downhill, diminished, or sinking from perspective. Somebody else says anything when approached for supper would be an illustration of decline.Slope retreat:
The gradual retreat of something like a scarp or perhaps the mountainous slope has been considered as an explanation for the erosion of backward as well as downwards.The slope is high and low on the land surface. The slope decline is the shrinkage of the slope angle, while the retreat is the change of the scrap position.
What is the slope?The slope is the high and low or up and down of the land surface. It can be convex, concave, straight, or compound.
Slope decline:
The decrease in the angle of slope as the incision of the river becomes uniform. The decline or shrinkage of the slope. This makes the slope gentler and it combines with regolith (the upper crust of the earth).
Slope retreat:
The geologic process by which the position of the escarpment changes. By escarpment is meant the slope lift of the hills or mountains that it can retreat for about ten kilometers.
Therefore, the above statements aptly explain slope decline and slope retreat.
