Water supply shortages will affect many people by the middle of this century. The process of desalination, removing the ____________________ from seawater, is one way to provide potable water.A) seed weed
B) contaminants
C) salt and minerals
D) bacteria and algae

Identify the fuel that could be classified as a nonrenewable or renewable resource.
A) biomass
B) geothermal
C) wind
D) tidal

Answers

Answer 1
Answer:

c removing salt and minerals

the process of desalination removes salt and minerals so water is safe to drink

A Biomass

This is because it is easily replenished naturally and over a short period of time but only if there is a large quantity of biomass available. If there is little biomass than it will be nonrenewable.

Answer 2
Answer:

Answer:removing minerals and salts

Explanation: took the test got it right

Why are invasive species dangerous to the environment?A. They pollute the environment.
B. They are voracious predators.
C. They threaten biodiversity.
D. They are nonrenewable.

Answers

Invasive species often upset the equilibrium maintained by the current ecosystem, so the answer would be C. They threaten biodiversity.

What are Invasive species?

An organism that is not native or indigenous to a certain location is referred to as an invasive species. Invasive species can seriously impact the local economy and ecosystem.

Non-native species are not always invasive. For instance, most of the food crops grown in the US, such as popular wheat, tomato, and rice varieties, are not local to the country.

A species must be easily adaptable for it to be invasive. It needs to multiply swiftly. It must cause damage to real estate, the local economy, or the local wildlife and plant life.

Therefore, Invasive species often upset the equilibrium maintained by the current ecosystem, so the answer would be C. They threaten biodiversity.

What sequence of events can lead to magma becoming soil

Answers

Crystallization is the sequence of events which can lead to magma becoming soil.

Crystallization is termed as the process by which a solid is formed whereby molecules are organized to a structure which is known as crystal. Crystallization occurs into major steps which are nucleation and crystal growth. 

Most of the organic molecules and minerals crystallize easily. Biochemicals particles for example proteins are difficult to crystallize. Crystallization can also be a solid to liquid separation technique where the transfer of a solute from liquid solution to pure solid crystalline phase occurs.

Magma can become soil through a sequence of events involving volcanic activity, weathering, pioneer plant colonization, organic matter accumulation, and the gradual development of soil over time.

What sequence of events can lead to magma becoming soil?

The sequence of events that can lead to magma becoming soil involves a process known as weathering and soil formation. Here is a simplified sequence of events:

1. Volcanic Activity: Magma rises to the surface through volcanic eruptions, depositing lava and volcanic ash on the land.

2. Primary Succession: Over time, weathering, erosion, and natural forces break down the volcanic rock and ash, creating a barren landscape.

3. Pioneer Plants: Hardy pioneer plants, such as lichens and mosses, begin to colonize the barren terrain. Their growth helps break down the rock further, contributing organic matter to the developing soil.

4. Soil Formation: As the pioneer plants die and decompose, their organic matter mixes with mineral particles, creating a thin layer of soil called "young soil" or "topsoil."

5. Succession Continues: Over time, larger and more complex plant species, including shrubs and trees, colonize the area. Their roots penetrate deeper, breaking up the rock and contributing more organic matter to the soil.

6. Soil Development: Through the ongoing cycle of plant growth, decay, and organic matter accumulation, the soil gradually becomes richer and deeper. The breakdown of minerals from the volcanic rock contributes to the fertility of the soil.

7. Mature Soil: After a long period of succession and soil development, the area is transformed into a mature soil ecosystem capable of supporting diverse plant and animal life.

It's important to note that the process of soil formation is complex and can take hundreds or thousands of years depending on various factors such as climate, topography, and the types of organisms present.
