Pollution
Pollution is the process of giving out contaminants such as smoke and carbon dioxide, and too much of a certain product such as light, heat and sound that both cause harm to the environment.

Hypothesis of when when a river is full of garbage?
A hypothesis is a testable prediction about some kind of phenomena. Regarding a river full of garbage, a good hypothesis might be, 'When the river is heavily polluted, the fish in the river will die.'

An infarct occurs when proper blood flow has been restricted to the point of tissue death. There are two types of infarcts, hemorrhagic and a white infarction.
gypsum

you can write about loss of habitat of animals, soil erosion, less rains causing droughts, deforestation, excess co2 in the atmosphere, global warming etc.
How are some nations working to protect the earth's resources?
creating laws to regulate the amount of pollution that is released into the air,
planting trees at the same rate they are being cut down,
teaching citizens about water consumption and waste
Phenology can be a useful tool in environmental monitoring.here what is phenology in this context?
Phenology is the study of how climate affects the environment. For example, when the birds start to go south for the winter, the climate will change or has already changed to cooler temperatures.
What do badgers do for the eco-system?
Badger hair is traditionally used to make various types of brushes, and in northern China their skin has been used to make rugs. Also, badgers may cut down on unwanted pests, since they eat insects and carrion.
Does littering killing your fish?
If litter gets into the ocean it may cause polution. This efects fish because if a fish is hungry it may eat the litter. Litter like ballons can be poisonus to fish. So if a fish eats a poisonis piece of garbadge i may become very sick and die. The moral of the story is litter kills fish.
What was the 1st mass produced car?
The first automobile to be mass produced in the United States was the 1908 Ford Model T
Wrong!!
The actual first car to be produced in the U.S was the Curved Dash Oldsmobile is credited as the first high-volume gasoline automobile It was introduced by the Oldsmobile company in 1901 and produced through 1907. offently miscredited to the ford!!, it was Olds who acctually came up with the idea of the production line
Wrong!!
i don't exactly know the model but i do know that the first mass produced car was made by Thomas Alva Edison.
How does moving water affect land?
Moving water affects the land in many ways. As a river bends, inertia in the water pushes into the outside bank, eroding it away. As this happens, on the inside bank sand is deposited and starts creating sort of a spit inside the river.
Trees and other vegetation thrive along the coast of rivers, known as buffer zones. This stops surrounding land, like urban or farmland, from affecting the river.
Why are thedifferent gases in air important to life on earth?
Without different gases there will be no air, if there is air, how can oxygen travel?
Does swallowing air cause gas?
Yes it some people cause of there gases are being backed up just like burping!
What is the difference between normal rain and acid rain since normal rain is acidic anyway?
Normal rain is slightly acidic but it occurs naturally, as oppose to acid rain caused by air pollution
How will life in water be affected if the sunlight penetrates deeper into the water?
The animals that can survive in the dark will probably not survive in the new light given that they are immune to the darkness. I used big words and im only 12 haha xD
Global warming was not invented by anyone; it is a scientific phenomenon resulting from increased greenhouse gas emissions due to human activities, such as burning fossil fuels and deforestation. The concept of global warming has been studied since the late 19th century, with scientists like Svante Arrhenius contributing early research on the greenhouse effect. Over time, extensive research has confirmed the ongoing impact of human actions on climate change, leading to widespread recognition and concern regarding global warming.
What causes a vehicle to backfire?
Improper engine timing usually
Could also be leaking / damaged intake valve(s)
or on an older engine with a carburetor if the accelerator pump is bad it will spit back when throttled up quickly
Is it safe to solder plastic and is it toxic?
Answer
If I'm a bit careless with words(there's brazing and welding too), solder is usually about joining two metal pieces together by adding a 3rd molten metal with a lower melting point where the pieces meet.
Some plastics also melt in heat, and can be used to join pieces of plastic together in a method very similar to soldering metal. It's usually done with a hot air gun with a pointy nozzle.
All types of soldering releases fumes, which are unpleasant if not outright toxic. All soldering should be done in a well-ventilated area. If you are doing lots of it, you should have a dedicated ventilation inlet righ by your work area.
Answer
By "solder" I'm presuming you mean to join using melted metal, typically for electrical conductivity (as in soldering components on a circuit board).
Since plastics, as a rule, do not conduct electricity; I'm going to guess you mean you want to solder some metal items to each other, perhaps on or through a piece of plastic.
Soldering typically involves high heat (on the order of 800 degrees Fahrenheit or more); most plastics melt or burn at such temperatures; and many plastics produce chemical fumes when heated, melted, or burned, some of which are toxic.
Another hazard of this is that molten plastic can cause serious burns on exposed skin, much like getting melted sugar on it.
I'd suggest against doing this unless you have a good reason, and do so in a well ventilated environment and protect yourself against burns if you do.
How long does it take to decompose a table?
I don't really knows how long it takes to decompose because it really depends on which material it is based on. So you would have to be specific.
There are diverse opinions and resources on overpopulation. I have linked below two sites, one that says yes and one that says no.
From my point of view, overpopulation is not a problem of number of people, but the behavior of those people.
If the population of the world expects to 'have' what our richest societies have, and that is what the poorer societies are striving for, then the answer is yes. For the entire world population to consume the resources of the earth and dispose of their waste on the scale that the richer countries do now, then it won't take long for the planet earth to become unlivable; a disaster. Of course, the more uninhabitable the earth becomes, the population will decline due to toxicity and hostilities as people blame each other and attempt to save what's left for themselves.
The other side of that coin is that there is room for more people if the world population learns to use resources wisely, recognize the long term consequences for their actions, and in general treat each other more humanely. In the history of the human race, this happens so rarely and on such a small scale that it doesn't affect the world as a whole. Can it be done? Therein lies the answer.
Does burning rubbish give off gas?
Yes it gives off carbon-dioxide, just like any other burning, it may also give off other chemicals, it depends what is in the "rubbish"
Answer:
Burning a mixture of organics and petrochemicals(ubbish) gives off a variety of gasses.
The principle gas is carbon dioxide from the actual cobustion - little or no CO is formed as there is lots of air.
The heat from the fjre volatilize some materials such as fatty acids and oils from plant and animal matter.
The heat may break down plastics to release many of the component monomers (styrene, ethylene, propylene)
If air is limited there may also be some soot (carbon particulate).
