Answer:
By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice coring has been around since the 1950s.
Based on what you learn from these resources, write a brief essay giving specific examples of how human activity has contributed to the problem of desertification in the Sahel region. How has the problem affected Lake Chad? How has it endangered the local population's way of life?
Answer:
Use of agricultural lands, poor irrigation practices, deforestation, and overgrazing.
Explanation:
Human activity has greatly contributed to the problem of desertification in the Sahel region. Factors such as use of agricultural lands, poor irrigation practices, deforestation, and overgrazing are the main problems created by human activities. Over extraction of water by humans for their daily needs is the main problem that greatly affected lake Chad. Due to lowering of water in the lake, the people that settle around the lake and depends on this lake migrated to other regions due to this water crises.
Answer:
Explanation:
Human activity, including irrigation practices, hydroelectric dams, and intense agricultural use, have led to desertification in the Sahel region. In addition, global warming has added to the problem. Over time, the soil becomes overused and sterile. As that dry and arid soil moves, it begins to encroach on local bodies of water. Lake Chad, as a result, has shrunk in size. Just 40 years ago, this lake contained 15,000 square miles of water. It now contains just over 500 square miles of water.
The locals of this region depend heavily on both fertile soil and healthy bodies of water for survival. Desertification can greatly endanger their way of life. For example, famers cannot produce the necessary crops, and fishers cannot rely on as much seafood. The article mentions that fishers who used to be able to fill hundreds of traps can now barely fill one. Desertification in the Sahel and its impact on Lake Chad will have a lasting effect and could possibly mean a different way of life for generations to come in the region.

Se refiere al comportamiento de los componentes del espacio geográfico, o a los procesos o fenómenos que suceden en un lugar en específico y no tienen un alcance significativo fuera de ese lugar.
La respuesta correcta para esta pregunta abierta es la siguiente.
A pesar de que no se anexan opciones o incisos para responder la pregunta, podemos comentar lo siguiente.
Se refiere al comportamiento de los componentes del espacio geográfico, o a los procesos o fenómenos que suceden en un lugar en específico y no tienen un alcance significativo fuera de ese lugar.
Este concepto se refiere a la "Escala Local."
Cuando nos referimos a la escala local significa que el evento o la situación sólo tiene un interés en el lugar específico donde sucede, y nada más. No llega a trascender a un nivel regional, estatal, o nacional. Eso quiere decir que no existe un efecto importante o no requiere de la atención de otras instancias de gobierno.
Significa que su magnitud es limitada y su alcance es proporcional.
La definición contenida en el enunciado se refiere a los comportamientos locales de los componentes del espacio geográfico, puesto que se mencionan que están circunscritos a un lugar en específico.
Análisis de una afirmación con respecto a las cuestiones fundamentales de la geografíaLa estudio en el ámbito de la geografía puede debe entenderse en dos componentes fundamentales que se relacionan entre sí:
Geografía física - Correspondiente a los elementos ecosistémicos, orográficos e hidrográficos de un entorno.Geografía humana - Correspondiente a los grupos humanos que se encuentran en un entorno determinado.De la interacción de esos dos elementos surgen especializaciones de la geografía tales como la geografía económica, la geografía política, la geografía económica, la geografía social y la geografía ecológica.
También el estudio de la geografía puede categorizarse en función del alcance de los procesos geográficos (i.e. locales, regionales, continentales, mundiales). Es evidente que la definición contenida en el enunciado se refiere a los comportamientos locales de los componentes del espacio geográfico, puesto que se mencionan que están circunscritos a un lugar en específico.

(GIVING BRAINILEST) Read the passage. Then evaluate the need for a solution and consider each solution suggested. Which solution do you think is more likely to be successful? Explain your reasoning.
People traveling to an island accidentally introduced mice into an ecosystem that previously had no mice. The population of mice quickly grew out of control. It started harming populations of native plants and birds. Scientists offered two solutions. One was to introduce cats to the island. The cats could hunt and eat the mice. The other suggestion was to introduce a disease that could infect the mice and reduce their population.
Read the assignment carefully and make sure you answer each part of the question or questions.
After you've written your response, go back and read it again to make sure your thoughts are clear.
Answer:
I would introduce the cats if it is a suitable environment for them. I say this because the disease could kill much more species than just mice. That could ruin the whole ecosystem by killing animals that are necessary for the ecosystem to function.
My suggestion would be to introduce cats, so that it could eat mice and reduce its population in the island.
Why cats would be needed in that island?If cats are introduced in that island and it suits them, they would hunt mice and the island would be free from mice.
But if disease is introduced into the island, it may harm other plants, animals and insects also. Disease may have harmful effects om environment as well. Cats will eat the mice which will lead to reduction in their population.
Therefore, we can conclude that cats should be introduced in the island.
