The correct answer is bar screening physically removes large objects or secondary clarifiers in wastewater treatment.
Clarifiers operate on the settling principle of gravity. Due to the quiescent circumstances offered in the Clarification zone, the heavier suspended materials settle in the clarifier. With the aid of moving scraper blades, the settled solids are swept to the center well designed for collecting sludge.
The secondary clarifiers eliminate wastes and suspended solids from the biological contactor units' rotating effluent. By allowing the wastewater to pass through the clarifiers at a slower speed than necessary for the larger particles to settle out, the settleable solids are removed.
To separate biological floc from the treated liquid waste stream, supplementary clarifiers are used. Most frequently, secondary clarifiers are addressed in combination with biological wastewater treatment systems for suspended growth.

difference between timber and medicinal plants
Timber plants and medicinal plants are two types of plants that differ in definition and usage.
Timber plants are tall perennial woody trees whose main trunks and branches are cut and used for aesthetic purposes. Medicinal plants are herbs whose parts are used for medicinal purposes.
Timber plants are used for construction, furniture making, paper manufacturing, and as fuel sources. Medicinal plants are used to cure bacterial, fungal, or parasitic diseases.

An ocean current that flows parallel to the coast is called a longshore current. Large waves that crash against the shoreline at an angle and force water down the length of the beach in one direction are what produces it.
This sheet of water can "catch" and carry beach debris back out to sea as it flows on and off the beach. Longshore drift is a mechanism that may significantly erode a shoreline.
In a "sheet-like" arrangement, water in a longshore current moves up the beach before returning to the ocean. This sheet of water can carry beach sand back out to sea as it passes over and off the beach.

What is groundwater and its advantages?
Groundwater is groundwater found in cracks and crevices in soil, sand, and rocks. It is stored and slowly moves through formations of soil, sand, and rock called aquifers.
It's pretty hard to imagine how much water is stored underground, but try it. The Ogallala Aquifer, which occupies most of the Midwest and South, holds more water than all the Great Lakes combined.Another advantage is that the water in aquifers is usually very clean to begin with, so cleaning is easy. Usually not contaminated with viruses, sludge, chemicals, etc.However, there is a problem and it is entirely our fault. We think that these aquifers hold so much water that they can be pumped indefinitely, but this is not entirely true. increased to the point where the water source was completely depleted. What is your source? aquifer. No matter how much water there was in an aquifer, a large, heavy-consuming population could deplete it, much like what happens with coal and oil. Overuse is a big problem.Another problem is contamination. Most often originate from human sources.

Answer:

Explanation:
the intrusive and extrusive, felsic igneous rocks are:
The intrusive and extrusive, felsic igneous rocks are Granite and rhyolite.
Extrusive and intrusive igneous rocks are divided into these two main categories. Lava, which is magma that has surfaced from beneath the Earth, is what gives rise to extrusive rocks. Intrusive rocks are created when magma cools and solidifies within the earth's crust.
When lava cools down inside the earth's crust, granite is created. It is a rock made of igneous intrusion. It is referred to as coarse-grained because the crystals are big. Granite and rhyolite have a tight relationship. Granite differs from it because its crystals are significantly finer. Because the crystals are so minute, they cannot be seen with the human eye. Rhyolite forms when lava cools down on or near the earth's surface, unlike granite. Extrusive igneous rock describes it. Rapid cooling causes it to develop, giving it a glassy look.

When individual water molecules escape as gas from liquid water, the process is called Evaporation. when water vapor molecules in the air bind together to form liquid water droplets, the process is called Condensation.
A liquid turns into a gas through evaporation. The forces of attraction between molecules cannot stop them from drifting away when a liquid is sufficiently heated or when the pressure on the liquid is sufficiently reduced. As a result, the liquid evaporates into a gas.
The transition from a vapor to a condensed form is known as condensation (solid or liquid).
The forces of attraction between molecules in a gas prevent the molecules from drifting apart when the gas is sufficiently cooled or, in many situations, when the pressure on the gas is increased sufficiently. As a result, the gas condenses into a liquid or a solid.
