Scientists claim that climate change is happening because Earth is warming. They also claim that humans have helped cause the warming by adding greenhouse gases to the atmosphere. Other people claim that Earth is not experiencing climate change because some winter days are still very cold. Use evidence to evaluate each claim about climate change.
help
this is science.
Answer:
There is solid proof that global warming is increasing and getting worse by t he day. The ice caps slowly melt more and more each year due to this which is a proven fact. On top of that, it has been proven that carbon emission by humans is bad for the environment and it helps increase the problem of global warming by weakening our atmosphere. As for the cold days, just because we have global warming doesn't mean the earth weather wont be cold. global warming is something that slowly happens and over time the temperature global has actually been increasing at a not very notice able pace.
Explanation:
Yes, climate is changing because of the human activities which are causing harm to the environment causing global warming.
What is global warming?Global warming is the long-term warming of Earth's climate system that has been seen from the pre-industrial period (between 1850 and 1900) as a result of human activity, principally fossil fuel combustion, which raises heat-trapping greenhouse gas levels in the atmosphere.
Evidence which claim about climate changeGreenland, Antarctica, and tropical mountain glaciers have all provided ice cores that illustrate how the Earth's climate responds to fluctuations in greenhouse gas levels. Tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks all contain ancient data.Yes, 97 percent of actively published climate scientists agree that people are to blame for global warming and climate change.Based on the data, nearly 97 percent of climate scientists agree that human-caused climate change is happening, according to the American Association for the Advancement of Science (AAAS).To know more about Global warming here

A pitcher throws a softball toward home plate. When the ball hits the catcher’s mitt, its horizontal velocity is 32 meters/second. The softball’s velocity goes to 0 meters/second in 0.8 seconds when caught. If the softball has a mass of 0.2 kilograms, what’s the force of the impact? Use F = ma, where .
Answer:
To calculate the force of impact F, first lets calculate the acceleration a of the ball:
a=v/t where v is the velocity of the ball and t is time
a=32/0.8=40 m/s²
To get the force F we need the Newtons second law:
F=m*a where m is the mass of the ball and a is the acceleration.
F=m*a= 0.2*40 = 8 N
So the impact force is F= 8 N.

can someone write about genetically modified foods and the genetic modification process?
Answer:
ok :)
Explanation: genetically modified organisms (GMOs) are being made by inserting a gene from an external source such as viruses, bacteria, animals or plants (etc) into foods. Genetically modified foods seem to be not as healthy as unmodified foods, according to research. also many people are against it due to the fact that some people go overboard and add too many genetically modified organisms, which causes health risks and unfortunately harms people. sometimes genetically modified food contains toxins and antibiotics. srry i couldnt find much on the process but this is based off my background knowledge so yeah
Compare the chemical reaction that causes the Statue of Liberty to look green with the chemical reaction that causes a bike to rust.
Both the situations are examples of corrosion. The green colour seen in statue of Liberty is due to the copper oxide formation whereas the resulting in bike parts is due to the formation of iron oxide in the surface.
What is corrosion?Corrosion is a chemical process by which the metals are destroying and change in colour. Metal surface when open to air or water will react with the oxygen forms corresponding oxides.
Corrosion is an electrochemical process where the oxygen acts as the anode and the metal surface cathode where the oxide deposits and the colour changes. Materials containing iron will react with oxygen forms a red iron oxide called rust which then completely corrode the metal.
Similarly, the statues are made of metal alloys containing copper. Copper also reacts with air or water forms the copper oxide which is green in colour that is why the statues are turning to a gree patchy colour over time.

Which of the following events could increase Earth's temperature?
Question 2 options:
A. a decrease in the relative percent of greenhouse gases
B. planting more trees
C. widespread removal of tropical forests
D. a reduction in the use of fossil fuels
Answer:
The answer is C & A.
Hope this helped you out!^^
Temperature measures the average kinetic energy of particles of the substances. Therefore, the correct option is option C that is widespread removal of tropical forests.
What is temperature?Temperature is used to measure degree or intensity of heat of a particular substance. Temperature is measured by an instrument called thermometer.
Temperature can be measured in degree Celsius °c, Kelvin k or in Fahrenheit. Temperature is a physical quantity. Heat always flow from higher temperature source to lower temperature source.
We can convert these units of temperature into one another. The relationship between degree Celsius and Fahrenheit can be expressed as:
°C={5(°F-32)}÷9
A decrease in the relative percent of greenhouse gases, planting more trees and a reduction in the use of fossil fuels will decrease the temperature of the earth. Widespread removal of tropical forests increase the temperature of earth.
Therefore, the correct option is option C that is widespread removal of tropical forests.
