Answer: large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.The idea of a large-scale displacement of continents has a long history. Noting the apparent fit of the bulge of eastern South America into the bight of Africa, the German naturalist Alexander von Humboldt theorized about 1800 that the lands bordering the Atlantic Ocean had once been joined. Some 50 years later, Antonio Snider-Pellegrini, a French scientist, argued that the presence of identical fossil plants in both North American and European coal deposits could be explained if the two continents had formerly been connected, a relationship otherwise difficult to account for. In 1908 Frank B. Taylor of the United States invoked the notion of continental collision to explain the formation of some of the world’s mountain ranges.
Explanation:
B is your answer because there was very little wood in the area
Answer:
La opción correcta es C. Los lagos son ideales para la construcción de centrales hidroeléctricas.
Explanation:
Una central hidroeléctrica es una central eléctrica que utiliza agua corriente o que cae para poner una turbina en movimiento y generar electricidad a través de este. El uso de energía hidroeléctrica no produce contaminación ni residuos radiactivos peligrosos. Por eso se considera que las centrales hidroeléctricas generan energía verde.
En este contexto, los lagos son fundamentales para la construcción de las represas que almacenan el agua que se utiliza para hacer funcionar las centrales hidroeléctricas, ya que en el caso de los ríos, muchas veces ocurre que el ancho del caudal no es suficiente para poder realizar una construcción efectiva, con lo cual se construyen embalses artificiales que son un gasto extra de tiempo y dinero.
Answer:
Mid latitude cyclone are low pressure regional cyclone system formed in 30 to 55 N or S. In this region continental polar and tropical air masses collide to form fronts. Fronts are the boundary between two air masses. This front pushes the warm air to the north and cold air to the south and generating a clockwise rotation. Cyclone starts to form from southwest and reaches mature stage to form a well developed cold front and warm front.This cyclone become weak, both cold and warm front merge as occluded front, this causes the snow and poor weather condition in northeast US, same time southwest is the formation zone, so mild temperature.
