Why Darwin's theory of evolution a theory in crisis?
The theory of evolution has passed on and is no longer just Darwin's theory and the only crisis in this theory is in the heads of delusional creationists.
How much water does a greenhouse need?
The amount of water needed in a greenhouse depends on the size of the greenhouse and the amount of irrigation it has. Plants in a greenhouse generally need far less water than regular plants.
Isn't evolution just a theory?
Yes, evolution is a theory. But it is not "just a theory" in the sense that you probably mean. In layman's terms, we might speak of a theory as simply an idea or an opinion, such as "Well, that's YOUR theory..." In science, it is something else entirely, and when something becomes scientific theory, it has been very well substantiated. It is more synonymous with the word "fact" in this usage, unlike the previous usage I used as an example. in fact, all scientific discoveries are considered theories. hell, the fact that our bodies are made up of cells that reproduce is still just a theory.
What is your theory on evolution?
I accept the modern theory of evolution by natural selection. You can not just on a whim put forth a scientific theory. I suggest you access a good dictionary. The scientific meaning of " theory " is generally the primary meaning.
Is Darwin's theory becoming expired?
Darwin's theory is no longer just Darwin's theory. In the 150 years + that the theory has been around it has been modified and strengthened by repeated testing and has made myriad predictions and generated a plethora of testable hypotheses. No, the theory of evolution by natural selection is not expired.
Are greenhouse gases just a theory?
Greenhouse gases do exist and are not just a theory. Scientists have known for hundreds of years that some atmospheric gases (water vapour, carbon dioxide, methane and others) absorb heat rising from the surface of the earth.
How does the increase in greenhouse gases support the theory of global warming?
Part of the theory of global warming is that greenhouse gases capture the earth's heat. If more greenhouse gases are added to the atmosphere then more heat will be retained.We can measure that levels of greenhouse gases have increased, and we can measure that temperatures have risen. These measurements thus support the theory of global warming.
What gas do plants use in a greenhouse?
Humorous answer: greenhouse gasses Correct Answer: Carbon dioxide, just like when outside and not in a greenhouse.
How can a pound of gasoline equals 3 pounds of greenhouse gas?
Short answer, it can't. Long answer, the "theory" is that the individual components of gasoline combine with components of the air when combusted to produce "greenhouse gas".
Why do you think greenhouse gases get that nickname?
Because they have the same effect as a greenhouse. They trap heat inside them, just like a greenhouse does to help the plants grow.
What is a good sentence with the word greenhouse effect in it?
The greenhouse effect is when gases get trapped inside the earths atmosphere and cannot get out so the sun heats them up and the earth gets warmer. just like a greenhouse
Why are some greenhouse gases and some not greenhouse gases?
"Greenhouse gas" is just a catchy term that means "traps heat." Due to the way the atmosphere is layered, some gases trap more heat than others; CO being about the weakest "greenhouse gas."
What are solutions for addressing green house gases?
One theory is to increase the input of greenhouse gases so that the next "ice age" can be averted.
What country has made the most greenhouse gasses?
China just recently surpassed the US as the largest producer of greenhouse gases.China
What does the greenhouse effect maintain?
The greenhouse effect maintains temperature. Another word for a greenhouse is "hothouse." Without the greenhouse effect of our atmosphere, earth's surface would be more like that of the moon--baked during the day and cold at night. Just not quite as severe, as the lunar day is a month long.
Why aren't greenhouse frames painted and why don't they rust?
cause they just dont
What provides strong observational support for the claim that greenhouse gases make a planet wamer than it would be otherwise?
Venus has a higher average temperature than Mercury. The fact that Venus is hotter than Mercury despite being nearly twice as far from the Sun tells us that its thick carbon dioxide atmosphere must warm it significantly-just as we expect from the theory of the greenhouse effect.
