What causes climate change?

Answers

Answer: As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history.

Generating power

Generating electricity and heat by burning fossil fuels such as coal, oil, and natural gas causes a large chunk of global emissions. Most electricity is still produced from fossil fuels; only about a quarter comes from wind, solar, and other renewable sources.

Learn more about generating power at UN.org

Manufacturing goods

Manufacturing and industry produce emissions, mostly from burning fossil fuels to produce energy for making things like cement, iron, steel, electronics, plastics, clothes, and other goods. Mining and other industrial processes also release gases.

Learn more about manufacturing goods at UN.org

Cutting down forests

Cutting down forests to create farms or pastures, or for other reasons, causes emissions, since trees, when they are cut, release the carbon they have been storing. Since forests absorb carbon dioxide, destroying them also limits nature’s ability to keep emissions out of the atmosphere.

Hot spots are one of the places where volcanoes form may be the result of cracks in the Earth

What is a hotspot ?

A hot spot is a location on Earth where the magma is hotter than the nearby magma. These locations could be over a mantle plume or beneath the crust, the rocky outer layer of the planet. The magma plume causes widespread volcanic activity causing the hard crust to melt and thin.

The tectonic plates are moving away from one another along constructive plate boundaries. To make room for rising, hot lava to flow on to the surface, the Earth's crust is split apart. In these conditions, volcanoes can occasionally occur, Iceland is one example.

Answers

A problem with the decline in newspapers is dwindling funds for paying trained reporters.

The decline of newspapers serves as both a case study and a tool for understanding and observing how a culture's beliefs change over time. Depending on the area, newspapers may be losing readers. Newspaper closures have been related in studies to losses in civic participation, rises in government waste, and rises in political division.

The decline of newspapers has a number of negative effects, particularly on the local level. The growing "nationalization" of municipal elections has also been related to the decline of local news. Numerous newspapers have reduced their most costly reporting initiatives, including overseas bureaus and investigative journalism, as a result of declining earnings. Investigations might take months, with no guarantee of success.

Answers

When you are traveling away from San Diego, CA along a meridian in a northern direction, as your latitude increases, you can expect the maximum solar zenith angle to decrease.

A solar zenith angle is the angle between the sun and a line perpendicular to the Earth's surface. It is the angle that the sun's rays make with the line that is vertical to the Earth's surface (at the point of interest) in the sky.The angle is always between 0 and 90 degrees. A zenith angle of 0 degrees indicates that the sun is directly overhead, while a zenith angle of 90 degrees indicates that the sun is on the horizon.

The solar zenith angle is affected by the latitude of the observer. As you move away from the equator towards the poles, the zenith angle increases, meaning that the sun is lower in the sky. Conversely, as you move closer to the equator, the zenith angle decreases, meaning that the sun is higher in the sky.

Compare and contrast Relative and Absolute age dating. Give an example of each.




If a rock has a radioactive parent to stable daughter product ratio of 12.5 (Radioactive) to 87.5% stable daughter, HOW many half-lives have passed?



If a rock has shown by its radioactive to stable ratio to have had 4 half-lives pass and the duration of each half life is 600,000 years. How old is the rock?

Answers

Relative age dating and absolute age dating are two methods used in geology to determine the age of rocks or geological events.

Relative age dating involves comparing the ages of different rock layers or fossils to determine their relative order of formation. This method does not provide an actual numerical age, but it helps establish a sequence of events. For example, if we find a fossil in a rock layer that is below another layer containing a different fossil, we can infer that the lower fossil is older.
Absolute age dating, on the other hand, provides a specific numerical age for a rock or event. This is done through techniques like radiometric dating, which measures the decay of radioactive isotopes. For instance, if we measure the ratio of a radioactive parent isotope to its stable daughter isotope in a rock sample, we can calculate the number of half-lives that have passed. In the given example, if the radioactive to stable daughter ratio is 12.5 to 87.5%, it means that 4 half-lives have passed. Each half-life lasts 600,000 years, so the rock is approximately 2.4 million years old (4 half-lives x 600,000 years).
In summary, relative age dating helps determine the sequence of events, while absolute age dating provides an actual numerical age based on radioactive decay.

At which point is ocean water the warmest? 1 2 3 4

Answers

Ocean water is typically the warmest at the equator, where solar radiation is most intense.

This is due to the fact that the sun's rays are most direct at the equator, and the water absorbs more of this energy than it does at higher latitudes. Additionally, the higher temperature of the water at the equator causes more evaporation, which further contributes to the higher temperature of the water in this region.

The temperature of the ocean water also varies depending on the depth and the season. Water near the surface tends to be warmer than deeper water because the sun's rays are able to penetrate the surface and warm the water. The temperature of the water also fluctuates with the seasons, with the warmest waters generally occurring in the summer and the coldest waters in the winter.

As a result of humans' increased use of the water in the Colorado River, "fisheries in the upper Gulf of California have been hurt."

This is because the Colorado River is currently being used for irrigation of farms, generation of hydroelectric power, and supply of potable water to the urban region in the surrounding areas.

This constant use of the Colorado River has greatly affected the marine lives inside it, as it forces them to migrate due to the forced direction of the water.

It has also reduced other organisms that can enhance the lives of the fisheries inside it.

Hence, in this case, it is concluded that the intense use of the Colorado River has affected the marine organisms in the river, including the fish.

Answer:

Higher temperature increases the speed of solubility

Explanation:

"Solubility" refers to the ability of a solute to be dissolved in a solvent. Solubility and temperature are directly proportional. This means that as the temperature increases, the solubility of a substance increases too. In the same manner, as the temperature decreases, the solubility of a substance decreases too.

High temperature produces high heat (increase kinetic energy) that triggers the solvent to break the solutes apart. This is mostly true for many solid-state solutions.

in the discussion of earth's annual energy balance, we saw that earth absorbed approximately 51 units of solar energy but emitted 117 units of infrared energy. what prevents earth from getting colder and colder?

Answers

In the discussion of the Earth's annual energy balance, it has been seen that the Earth absorbed about 51 units of solar energy but emitted 117 units of infrared energy. The Earth is prevented from getting colder and colder by the greenhouse effect.

The greenhouse effect is a process that takes place in the Earth's atmosphere in which greenhouse gases (carbon dioxide, methane, and water vapor) trap some of the outgoing energy from the Earth's surface, thereby warming the planet's lower atmosphere and the surface. The energy is trapped because of the greenhouse gases, which act like a blanket, keeping the planet warm. If the greenhouse gases were not present in the Earth's atmosphere, most of the infrared radiation would be lost into space, resulting in a much colder planet.

The Earth's annual energy balance refers to the balance between incoming solar radiation and outgoing infrared radiation. The Earth's energy balance is a dynamic process in which energy is constantly being absorbed and emitted, but over the long term, the incoming energy and outgoing energy are balanced.Therefore, the greenhouse effect is the process that prevents the Earth from getting colder and colder despite emitting more energy than it absorbs.
