Answer:

fastest in rivers, slowest in groundwater

Explanation:

Water bodies undergo self purification by conversion of pollutants into harmless substances through various factors such as:

1. Production of Oxygen as a by-product of photosynthesis by aquatic plants. The oxygen helps in the self- purification of the water body.

2. Aquatic bacteria and plants also help in the release of nutrients which helps in self purification by decomposition of matter in the water.

Rivers, lakes and groundwater are the options. However the largest water body in these options is the River and it contains more amounts of oxygen and aquatic plants which makes self purification faster.

The Lakes are second in size to the river.

The Groundwater contain lesser amounts of oxygen and aquatic plants which makes it the slowest in self purification.

Answer:

​fastest in rivers, slowest in groundwater

Explanation:

For rivers, lakes and groundwater, self-purification is ​fastest in rivers and slowest in groundwater.

When groundwater becomes contaminated, it tends to remain contaminated because the dissolved oxygen levels are low or non-existent.

Given: EF is a diameter of the circle Find m∠EGF. A) 45° B) 60° C) 90° D) 100°
Law Incorporation [45]

Answer:

∠EGF = 90°

Explanation:

Question is incomplete as the attachment is missing.

To solve this I'll make an assumption that ∠EGF is an angle inscribed in the circle.

Given that

Line EF is a diameter;

Then the arc formed by EF is 180° (semi circle).

The inscribed angle theorem states that an angle θ inscribed in a circle is half of the central angle 2θ that subtends the same arc on the circle.

So, the inscribed angle

Arc EF = 2 * ∠EGF

Make ∠EGF the subject of formula

∠EGF = ½ EF

∠EGF = ½ * 180°

∠EGF = 90°

If normal faults uplift a block of rock, a fault-block mountain forms. What are some real world examples of fault block mountain
Rom4ik [11]

Answer:

A perfect example of fault-block mountains can be found throughout the territory of the Republic of Macedonia where every single mountain is formed in this manner.

Explanation:

The mountains can be formed in several different manners, one is by an uplift of a block of rock by a normal fault. The mountains that form in this manner are usually not very large in area, though they can reach significant heights. Many regions in the world have mountains formed in this manner, but probably the best examples are the mountains of the Republic of Macedonia.

This small country is actually the country with the highest number of mountains in the world. It has almost 60 separate mountains in its small territory. The reason for this is that it is located near the complex convergent boundary of Eurasia and Africa. All of the country's territory is divided into miniature crustal pieces with a lot of faulting. Each of the numerous mountains has formed because of the uplift of block of rock by normal faults, and they are all relatively small in area, but they range in height anywhere from around 1,000 m above sea level to over 2,700 m above sea level. Some of the mountains are Korab, Jakupica, Jablanica, Stogovo, Maleshevo Mt., Belasica, Osogovo Mt., Nidze, Kozhuf, Shar Mt., Busheva Mt., and many others.
