It is best to say that marine debris _______.
Answers
Marine debris are among the biggest threats in the oceans nowadays. These include materials that are intentionally or unintentionally left in the ocean or any marine environment. Marine debris may include cigarette butts, food wrappers, bottle caps, straws, grocery bags and others.
It is best to say that marine debris is harmful to the environment. Marine debris' detrimental impacts on marine ecosystems, wildlife, and even human health have made it a major global concern.
Any human-made garbage that finds its way into oceans, seas, or other bodies of water is referred to as marine debris, also known as marine litter. It includes a variety of substances, such as rubber, paper, glass, metal, and plastic. The purpose of this note is to clarify the origins, effects, and potential remedies of this urgent problem.
Damage to Marine Life: Marine species are seriously at risk from marine garbage. Injuries, asphyxia, and even death can result when animals like sea turtles, seagulls, whales, and dolphins get tangled in garbage or mistake it for food. Damage to Ecosystems: Sensitive habitats including coral reefs, seagrass beds, and mangroves can suffer damage from marine trash. It interferes with their natural processes, has an impact on biodiversity, and changes nutrient cycles.

Coal combustion causes a chemical change. Burning coal in a furnace will result in a chemical change. Therefore, option A is correct.
What is chemical change ?
A chemical change is the transformation of one material into another, the formation of new materials with different properties, and the formation of one or more new substances. It occurs when one substance reacts with another to form a new substance.
Coal combustion causes a chemical change. The main component, carbon, is converted to carbon dioxide when coal is burned. This process is irreversible.
When carbon is burned, it produces carbon dioxide, and hydrogen produces water. Each of these reactions generates a different amount of heat. Because this process cannot be reversed, coal combustion is a chemical change.
Thus, option A is correct.

Answer: Option (C) is the correct answer.
Explanation:
Solid and liquid are the states of matter. Plasma is also a state of matter where a number of electrons move freely around the nucleus of an atom.
Whereas water is a liquid itself and liquid is a state of matter but water is not a state of matter.
Therefore, we can conclude that water is not a state of matter.
is not a state of matter.
Further Explanation:
Matter:
Anything that acquires space and has mass is termed as matter. It is made up of atoms. These atoms can be bonded so strongly or can be far apart from each other. The states of matter can be classified on the basis of features that are visible or can be felt.
States of matter:
1. Solid
It has a definite shape and volume. These are generally hard and have a regular arrangement of its constituent particles. These can be amorphous or crystalline. The intermolecular forces in the solids are very strong and thus the motion of particles in solid is almost negligible. Rock, wood, sugar, and diamond are examples of solids.
2. Liquid
It has a definite volume but can have the shape of any container in which it is placed. The intermolecular forces in the liquids are weaker than that in solids and thus the motion of particles in liquids is more as compared to solids. These have the property to flow. Water, mercury and bromine are examples of liquids.
3. Gas
It has neither a definite shape nor a definite volume. These are highly compressible and have an irregular or disordered arrangement of its constituent particles. The intermolecular forces in the gases are the weakest and thus the motion of particles in a gas is very high. Oxygen, hydrogen and carbon dioxide are examples of gases.
4. Plasma
It has neither a definite volume nor a definite volume. It is present in ionized gases but its uniqueness differentiates it from gases. Plasma contains free charges that make it conductive. Stars and neon signs are examples of plasma.
So solid, liquid and plasma are the states of matter. But water is an example of liquid and therefore an example of a state of matter. Therefore water is not a state of matter.
