Could somebody explain fracture throughly? It is on the rocks and minerals topic

stepladder [879]

Fracture is the tendency of a mineral to break along curved surfaces and non-straight surfaces. Cleavage is when it breaks into flat pieces.
Hope this helped!

How could erosion affect humans and wildlife that live near the river? Explain your answer.

Minchanka [31]

Answer:

Erosion can cause water in the rivers to become heavily polluted. The water might carry pesticides, heavy metal ions and other toxic wastes. When this water will be used for irrigation purposes, the growth of plants will be heavily affected by them.

When humans use water this contaminated water from the rivers, it will led to many diseases in humans. Also, the wild- life animals which depend on this river might take in toxic compounds due to which they might die.

oksano4ka [1.4K]

Answer:

The answer is A

Typhoons are basically like hurricanes, formed by weather and climate.

Tornados are formed by weather activity.

Floods can happen from weather or tectonic activity, but its more of an indirect effect rather than a direct one.

Earthquakes are from tectonic activity, the right of fire is the boundary of a tectonic plate.

In nuclear fission and fusion reactions mass is converted into energy. The average person in US uses around 100,000,000 J of ene

daser333 [38]

Answer:

a) The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) The energy that would be released if a 60 kg person were converted entirely into energy is $5.4\times 10^{18}$ Joules.

c) 180 years would this amount of energy support a population of 300 million.

Explanation:

a) Average energy consumed by single person of US = 100,000,000 J/year

Then 300 million US citizen will consume:

300 million = 300 × 1,000,000 = $3\times 10^8$

The yearly energy consumption for a US population :

$100,000,000 J/year\times 3\times 10^8=3\times 10^{16} J/year$

The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) $E = m\times c^2$

E = Energy from converted mass of m

c = speed of light

Given mass of person = m = 60 kg

$E=60 kg\times (3\times 10^8 m/s)^2 = 5.4\times 10^{18} J$

c) Energy calculated in part (b) = $E=5.4\times 10^{18} J$

The yearly energy consumption for a US population of 300 million in an year = $3\times 10^{16} J/year$

Let the that would be supported by $5.4\times 10^{18}$ Joules of energy be x.

$x\times 3\times 10^{16} J/year=5.4\times 10^{18} J$

$x=\frac{5.4\times 10^{18} J}{3\times 10^{16} J/year}=180 years$

180 years would this amount of energy support a population of 300 million.

Explain why the town in canada is colder than the amazon village<br>

tigry1 [53]

Answer:

Canada is colder because it is up North. It isn't as humid as it is in the south so it makes the air more dry and thin, making it colder. Where in the Amazon, it is warm and moist because it is by the equator and is near the tropics.

Explanation:

I hope this can help... I just answered with what I learned in science...
