Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.


Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.

Answers

Answer:

The total amount of carbon in the world is not changing. Because matter is

conserved in all processes and reactions, carbon must decrease in one place if it increases in another.

To clean their drain pipes, some people make a solution of baking soda and vinegar. Baking soda, also known as sodium bicarbonate (NaHCO3), reacts with acetic acid (C2H4O2) in vinegar. When these substances combine, the solution becomes colder, and sodium acetate (NaC2H3O2), water (H2O), and carbon dioxide gas (CO2) form. The gas creates bubbles that help clean the inside of the pipes. is this reaction endothermic or exothermic?

Lightning rods (and the accompanying protection system) are designed to protect a house or building from a direct lightning strike and, in particular, a lightning-initiated fire, Static electricity is the result of an imbalance between negative and positive charges in an object. These charges can build up on the surface of an object until they find a way to be released or discharged. One way to discharge them is through a circuit, and An electroscope is an early scientific instrument used to detect the presence of electric charge on a body. It detects charge by the movement of a test object due to the Coulomb electrostatic force on it.

Answers

1. Manipulated: Water

Responding: Growth Height

2. Manipulated: Chocolate Given

Responding: Amount of Homework

3. Manipulated: Trees with Leaves

Responding: Number of Bird Nests

4. Manipulated: Acid Rain

Responding: Fish Population

5. Manipulated: Calcium Given

Responding:  Bone Strength

Think about the manipulated variable as the changing item in the experiment. If this changes, the response will. (This is the Independent Variable)

Think of the Responding Variable as the result of the variable only can change when Manipulated is changed. (This is the Dependent Variable)

Hope This Helps :)

Manipulated variable in each case are watering of plants, number of chocolates, trees having leaves,water in acid rain, amount of calcium respectively and responding variables are growth  height, amount of homework,number of bird nests,fish population,bone strength.

What are variables?

Variables are defined as any characteristics, number or quantity which can be measured . It can also be called as a data item . It is called as variable because they can vary and can have variety of values.

There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variable  which do not change

Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Explanation:

hope this helps dude

According to the concept of solubility, carbonic acid is a mixture of water and carbon dioxide.

Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.

The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

A mixture of water and carbon dioxide under high temperature and pressure forms carbonic acid as it is highly soluble,thus carbonic acid is a mixture of water and carbon dioxide.

mild winters
hot summers
many tall trees
moderate amounts of precipitation

Answers

Answer: D : moderate amounts of precipitation

Explanation:

The one characteristic that temperate marine and temperate continental climates have in common is moderate amounts of precipitation. Thus, the correct option for this question is D.

What is Climate?

Climate may be characterized as the long-term pattern of weather in a particular area. It is different from the weather in a way that can change from hour to hour, day-to-day, month-to-month, or even year-to-year.

According to the context of this question, A maritime climate is influenced by a nearby ocean. A continental climate is influenced by nearby land. The temperature of offshore currents affects nearby land areas.

A maritime climate is less extreme than a continental climate because the ocean moderates temperatures. Due to this, both temperate marine and temperate continental climates have moderate amounts of precipitation.

Therefore, the correct option for this question is D.
