According to the passage, carbon dioxide is the most abundant greenhouse gas on Earth. What is the leading cause of Carbon Dioxide rising in the last 100 years?
Answer the question using the CER strategy. Be sure to use evidence from source 1 and 2.
Answers
Answer:
Human activities, especially the burning of fossil fuels like coal, oil, and natural gas, are primarily to blame for the rise in carbon dioxide levels over the past 100 years. Carbon dioxide is produced as a byproduct of combustion when these fossil fuels are burned for transportation, industrial processes, energy production, and other uses. Together with other greenhouse gases, this human-caused release of carbon dioxide has significantly boosted atmospheric carbon dioxide concentrations, causing the greenhouse effect and amplification of global warming and climate change.

Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters west. His car was 20 meters from the starting line. This took 5 seconds.
What is the car’s average velocity?
4 m/s east
4 m/s west
12 m/s west
12 m/s east
Answers
The average velocity can be found by calculating the total displacement of the car and dividing it by the total time.
The car's average velocity is "4 m/s west".
First, we will find the total displacement as follows:
Total Displacement = 20 m (East) + 40 m (West)
Taking East direction as positive and west direction as negative, we get:
Total Diplacement = 20 m - 40 m
Total Displacement = - 20 m = 20 m (West)
Now, the average velocity of the car will be:
\(Average\ Velocity = \frac{Total\ Displacement}{Total\ Time}\\\\Average\ Velocity = \frac{20\ m\ (West)}{5\ s}\\\\\)
Average Velocity = 4 m/s west
The attached picture shows the description of average velocity.

Situation -- Predicted Motion
How is motion predicted?
Newton's second law of motion says that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. You can use it to predict the motion of an object. The net force is the vector sum of all the forces that act on the object.
Rolling down an open

What causes an object to roll down a ramp?
When you lift an object up off the ground, it has potential energy due to gravity. So when you roll a ball down a ramp, it has the most potential energy when it is at the top, and this potential energy is converted to both translational and rotational kinetic energy as it rolls down.
Throwing in the air
Analyzing motion for objects in freefall
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration g, the magnitude of velocity decreases as the ball approaches maximum heigh.
Dropping on the floor
The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. ... The direction of the acceleration due to gravity is downward (towards the center of Earth). In fact, its direction defines what we call vertical.

Answers
Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

What are the three types of heat transfer in the Earth’s atmosphere.
Answers
Answer:
Radiation, conduction, and convection.
Explanation:
Radiation:
Radiation heat transfer occurs through electromagnetic waves. Unlike conduction and convection, radiation does not need a medium for transmission. Solar radiation energy traverses a 93-million-mile vacuum to warm the EarthConduction:
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. Conduction occurs more readily in solids and liquids, where the particles are closer together, than in gases, where particles are farther apart.Convection:
The process by which heat is transferred by the movement of a heated fluid, such as air or water.What two gases in the atmosphere do animals and plants need to breathe and grow?

Which of these correctly describes what would happen to a system if 100 J of heat energy is added to it?
1. The potential energy of the system will increase and this will increase the attraction between its particles.
2. The strength of the bonds in system will increase and this will decrease the speed of its particles.
3. The kinetic energy of the system will increase and this will increase the speed of its particles.
4. The kinetic energy of the system will decrease and this will decrease the speed of its particles.
Answers
The correct statement to describe that when a 100 J of heat energy is added to the system, then the kinetic energy of the system will increase and the speed of the particles will also increase. Hence, option 3 is correct.
What is Kinetic energy?The force that an object has because it is moving is known as kinetic energy in physics. It is defined as the quantity of effort required to accelerate anybody of a specific mass from rest to its specified velocity. The body keeps its kinetic energy after acquiring it during acceleration, barring changes in speed.
When slowing from its current pace to a condition of rest, the body expends the very same amount of energy. Any term in the Lagrangian of a system that has a derivative in regard to time is formally referred to as kinetic energy.
When the energy is added to the system the gap between the particles will increase due to which the velocity of the molecules will increase and with increase in the velocity the kinetic energy will also increase automatically.
