Answer:
The correct answer is A. Greenhouse gases allow visible light to pass through and warm the Earth's surface, and prevent heat energy from radiating back out into space.
Explanation:
The greenhouse effect of the gases is due to the fact that they transmit sunlight at a higher frequency than infrared, which heats up soil, trees and water. That heat cannot then radiate into space again like infrared radiation because the greenhouse gases partially absorb it. The effect is that the Earth's temperature rises until a completely new equilibrium temperature is reached. The most significant greenhouse gases are water vapor, carbon dioxide, methane, and tropospheric ozone.
The concentration of greenhouse gases in the atmosphere is constantly increasing at an accelerating rate due to human activities. The annual growth rate is currently two millionths of a year.
Answer:
Sustainable development refers to development that meets the needs of the present generation without compromising the needs of the future generations.
Explanation:
This definition of sustainable development was first introduced after the Brundtland Commission Report. It explains that humans social, economic, and environmental activities should be done in balance. Also, the Report further noted the driving force behind humans activities is "needs"; and as such this "needs" should be kept in balance.
Answer:
1- Efectivamente, hoy en día nos encontramos viviendo en un mundo globalizado, ya que se trata de un sistema mundial interconectado, donde todas las sociedades y gobiernos tienen una comunicación fluida y constante entre sí en forma rápida y dinámica. Esto se ha logrado a través del desarrollo de los medios de comunicación, que permiten la conectividad a gran escala.
2- Un aspecto positivo de la globalización en mi vida personal es que el desarrollo de las comunicaciones y las tecnologías me permite poder comunicarme con personas de mi familia que viven en otro país a decenas de miles de kilómetros de distancia, con solo apretar un botón y esperar tan sólo unos pocos segundos. Es decir, la globalización acorta las distancias y reduce los tiempos, uniendo más a las personas y, por ende, a los pueblos y países.
3- Un efecto negativo de la globalización es que todos los eventos políticos y sociales que ocurren en un país tienen repercusión en los demás países. Por ejemplo, una ley en los Estados Unidos puede influir en el desarrollo del comercio en Latinoamérica, influyendo negativamente en las economías de países con menor desarrollo, pudiendo causar problemas económicos a estos.
This is an absolute address of a place, which means that you can find this address without knowing anything else, such as addresses of other places. (so the answer is: absolute address or absolute location of a place)
Another kind of address would be be a relative address, such as "to the left of the school"
