What happens at a convergent boundary?

A. Magnetism occurs as lithospheric plates are attracted toward each other by gravity.

B. Mountains form as lithospheric plates move side by side past each other.

C. Earthquakes occur as lithospheric plates move away from each other.

D. Collisions occur as lithospheric plates move toward each other.

Answers

Answer:

At convergent boundaries, collisions occur as lithospheric plates move toward each other.

Explanation:

A is not correct because the movement of the tectonic plates is not driven by magnetism.

B is not correct because at this type of boundary the tectonic plates move toward each other, not slide past each other.

C is not correct because the plates move toward each other at this type of boundary, not move away from each other.

D is correct because at this type of boundary the plates move toward each other, and as they do collisions occur, resulting in the formation of mountains and subduction zones.

Which statement best describes the characteristics of areas near the equator?
A
Areas near the equator get less direct sunlight so the temperatures are lower.

B
Areas near the equator get more direct sunlight so the temperatures are higher.

C
Areas near the equator have more yearly rainfall so the temperatures are lower.

D
Areas near the equator have less yearly rainfall so the temperatures are higher.

Answers

Answer:

B . Areas near the equator get more direct sunlight so the temperatures are higher.

Explanation:

At equator, the sun is always over head and hits the surface directly. The surface is no at an angle to the sun.

The insolation here is very great and they received more direct sunlight.

Due to the high insolation, the temperature is higher than most part of the earth. Rainfall levels are also high as rain cloud easily forms here. In most equatorial region, both temperature and rainfall is high all year round.

solving the system of equation x--2y=5 and 3x+15=-6

Answers

x=-7

y=-6

Further Explanation  

One variable linear equation is an equation that has a variable and the exponent number is one. Can be stated in the form:

ax=b  ax + b = c,

where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

ax+by=c  

x, y = variable

x--2y=5 ⇒ equation 1

3x+15=-6 ⇒ equation 2

Solve equation 2 for x

[tex]\tt 3x+15=-6\\\\3x=-21\\\\x=-7[/tex]

Input x to equation 1 for y

Answers

Answer:

Some of the natural resources found in Latin America are oil, timber, and water.

Explanation:

Latin America is a region that is rich in numerous natural resources. Some that stick out are the oil, timber, and water. The oil is mostly found in the northern, northeastern, and eastern parts of this region, the timber in the northern and central parts, and the water is abundant across most of the region.

The constantly growing demand, unfortunately, has led to large-scale destruction of the forests and endganering a lot of species.The water is abundant in most of this region which has led to a lot of exploitation of the same, mostly in the energy, water supply, and agriculture industries. The energy production has led to a change of the water properties and blocking the movement of the species living in water, the water supply hasn't yet caused any problems, while the agriculture has led to big pollution.
