Which of the following statements are correct about the nitrogen cycle? Check all that apply.

Lightening oxidizes N2 to nitrogen oxides

There are nitrogen sinks in both water and soils

Bacteria are part of the nitrification portion of the nitrogen cycle

Bacteria are part of the de-nitrification portion of the nitrogen cycle

It contains nutrients such as nitrates, nitrites, and ammonia, which are essential to all life on earth.

Humans have interrupted the nitrogen cycle with excessive use of fertilizers

One of your classmates states: "Acid rain, is a consequent of climate change that results when compounds like sulfur dioxide and nitrogen oxides...under go chemical reaction in our atmosphere." Please gently correct this classmate with clear links between relevant molecules and the consequences of having too many of each type of molecule in our atmosphere.

Which of the following statements can be considered as facts? Check all that apply.

Question 9 options:

Carbon dioxide, CO2, is a greenhouse gas.

The burning of fossil fuel (or any other carbon-based fuel) releases carbon dioxide

Human activities have been increasing CO2 emissions while taking away CO2 sinks

Humans are too insignificant to change our planet

Too much of anything in nature upsets her balance.

We live in a world of infinite resources

A co-worker tells you that 400 ppm of CO2 is not a big deal.  After all, that is 0.04% of our atmospheric content.  What’s the big deal with such a small part of our atmospheric content?  Please respond in one to two sentences demonstrating your ability to think critically and analytically.

Which of the following statements are correct about the Jevons paradox? Check all that apply.

Question 16 options:

It was first formulated due to increasing coal consumption despite decreasing coal reserves

It states that technological progress increases the efficiency of resource utilization, thus enabling increased demand for that resource despite depletion of that resource.

It has been confirmed for all natural resource use

It states that humans continue to use natural resources as thought the are infinite even though we live in a world with finite resources

It states that humans are emotional animals.

Which of the following statements are correct about the phosphorus cycle? Check all that apply.

Question 20 options:

It contains a nutrient, phosphate, which is essential to all life on earth.

There are phosphorous sinks in both water and soils.

One of the issues with human interruption of the phosphorous cycle is excessive runoff of phosphates.

Phosphorous is present in all three phases, gas, solid, and liquid

It is found as phosphorous in nature

Human bodies are part of the phosphorous, nitrogen, carbon, and sulfur cycles.

In a previous class, a student stated "When we burn coal, oil, or gas, carbon dioxide is released into the atmosphere. This gas causes stratospheric ozone depletion and tropospheric formation because the gas is making this boundary expand." Please gently correct this student with a few well-chosen sentences.

Question 25 options:

Save

True

False

Explanation / Answer

Ques1. yes it is true and mainly it contrain sulphur adn that also in form of dimethyl sulphide.

Ques2. here CFCs and Nox are the main molecules playing a vital rule in ozone depletion.

CFCl3 + electromagnetic radiation Cl· + ·CFCl2

ClO + O3 Cl· + 2 O2Cl· + O3 ClO + O

and same thing is performed by  nitric oxide radical.

Ques3.

Buying more stuff impacts the environment. Because they are processed products and are manufactured in a industry and that industry releases gases like CFCs and No which are harmful.
