A respeito do extrativismo mineral, marque a alternativa correta. O Brasil é pobre em reservas minerais. O extrativismo mineral não gera impactos ambientais. O Brasil é rico em minérios como: nióbio, ferro, manganês e alumínio. No território brasileiro não há reserva de nióbio.

Answers

Answer:

O Brasil é rico em minerais como: nióbio, ferro, manganês e alumínio.

Explicação:

Altas reservas de nióbio, ferro, manganês e alumínio estão presentes no Brasil. O nióbio é um metal muito precioso e importante que é usado como ligas porque fornece resistência ao metal em uma temperatura muito baixa. É usado principalmente em foguetes porque a temperatura do espaço é muito baixa, cerca de -270 Celsius, o que é insuportável para o aço, então ele quebra, mas a liga com o nióbio o torna mais difícil nessa baixa temperatura. É por isso que o nióbio é um metal muito caro.

The birthrate and death rate were about equal.
B.
The death rate far exceeded the birthrate
C.
The birthrate was much higher than the death rate.
D.
This question cannot be answered using the given information.

Answers

C

Given that the World population changed little between this time, we can gather than the birth and death rates were similar, since they seem to cancel each other out from 1200-1400. To clarify, think of this. If you add something to a total (think births to population), but take away the same number (think deaths from population) you end up with the same total as before. Because of this, A is the correct answer choice (The birth rate and death rate were about equal).

Answers

Answer:

Wilderness areas are generally protected areas that have a high level of biodiversity, endemic and endangered species.

The use of fire even if they are controlled fires is not a useful practice, especially since it leads to the fragmentation of forests, geographical environments and the destruction of living habitats.  

Fires can affect both the area that is prone to controlled fires and other wild areas.

Explanation:

Lines b and c are parallel. Horizontal and parallel lines b and c are cut by transversal a. Where line b intersects line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: (13 x + 9) degrees, 2, 4, 3. Where line c intersects line a, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 6, (5 x + 9) degrees, 8. What is the measure of Angle6?

Answers

Answer:

  54°

Explanation:

We believe the intended angle numbering is as shown below. This means the marked angles are supplementary, so ...

  (13x +9) +(5x +9) = 180

  18x +18 = 180

  x + 1 = 10

  x = 9

Angle 6 is congruent to (5x+9), so has measure ...

  (5(9) +9) = 54 . . . . degrees

Angle 6 is 54 degrees.
