Answers

Answer 1

Answer:

C) the rock surrounding the ore was too hard for picks and hammers.

Explanation:

Miners realized that the newly discovered Comstock Lode would require different technology than usual instruments of mines in California because  the rock surrounding the ore was too hard for picks and hammers. The rocks surrounds the ore is very hard which can't be broken with the help of picks and hammers so for the extraction of ore, new technology is needed to extract the ore from the rocks.

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.

In August 2005, Hurricane Katrina wreaked havoc on the Gulf Coast. It was the costliest and one of the deadliest hurricanes in US history. Since that time, the simulations that meteorologists run to track and model hurricanes have significantly improved. With global climate change, scientists expect the hurricane season to become longer and the number of large storms to increase. However, they expect the advances in modeling to improve our ability to predict and prepare for storms in the future. Which are contributing factors to the improvements in modeling and simulation of hurricanes

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.

Answers

1. Wind energy :-

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.

Differentiate between slope decline and slope retreat​

Answers

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.

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?

Answers

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.
