The function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.
What is subsurface mining?Subsurface mining is the process in which mineral ores are too deep to extract at with this mining techniques, subsurface mining methods are used .
An advantage and good thing of subsurface mining is that it will not disturb land than surface mining it only disturbs less than one-tenth the surface amount of land as surface mining and the method.
Therefore, the function of tunnels and passageways in subsurface mining to drain underground lakes where minerals are found. option C is correct.

The local newspaper has published the passage below.
Last week, scientists released incredible images of aurora australis, known as the northern lights, as seen from the Hubble telescope. The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn.
Which statement in the news passage above is inaccurate?
The aurora australis cannot be seen from space.
The Hubble telescope does not orbit our planet.
The aurora australis is known as the northern lights.

Explanation:
The cycle of water erosion has been here since forever thanks to the rain rivers, ponds lakes, the sea and the ocean because it first starts off with the rain then the rain fills up the lakes and pond and start rivers and the rivers lead to the sea and ocean and from there the water evaperates then it rains again and the lakes and ponds help with the evaporation.
Write a paragraph on why food needs to be digested. :)
Please hurry I need it.
Answer: You die if no digest
Explanation:
Food needs to be digested because your body can't contain large stuff whole, so it has to be converted into a smaller amount. For Instance, if you were to eat a entire turkey then your body would just explode I guess if you wouldn't digest it. Also, without digesting food you can't enter new food into your body. Therefore, this is why food needs to be digested.

Explain the flow of energy in the food chain and why stored energy is an important concept of it.
Answer:
"The process of transfer of energy to various trophic level of food chain is known as flow of energy. Energy flow in ecosystem from energy source to autotrophs to heterotrophs."
Explanation:
The energy flow from the primary members, plants to the other level of organism in food chain. Storage of energy is very important because, the stored energy in plants are distributing to all other levels in food chain and utilizing for activities.
What is energy distribution in food chain ?The sun is the main source of energy for practically all ecosystems on earth. Energy moves from one trophic level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose.
Primary producers are then consumed by primary consumers, who are in turn eaten by secondary consumers, and so on. The sun is the main source of energy for practically all ecosystems on earth.
Energy moves from one trophic level, or level of the food chain, to the next as primary producers take energy from the sun to make their own food in the form of glucose. Only 10% of energy is distributed to the other level and 90% are lost to the surroundings.

Solid pills have less surface area and will not dissolve.
C.
Solid pills have more surface area and will take longer to dissolve.
D.
Powders have less surface area and will dissolve faster.
Answer:
A.
Powders have more surface area and will dissolve faster.
Explanation:
please mark this answer as brainlest
The solute-like solids can dissolve in the solvent through the dissolution process. Powders have more surface area that permits more dissolution.
What is surface area?The surface area is the amount of space covered or occupied by an object. It is directly dependent on the solubility and increases with an increase in the solubility.
The surface area of the powder is more compared to the solid pill and hence, the solubility of the scoop of powder is more than the pill.
Therefore, powder dissolves faster because option A. has more surface area.
