Dr. Alley once helped a Grand Canyon ranger answer a tourist’s question: "Why is the Canyon wider at the top than at the bottom?
lina2011 [118]

Complete Question:

Dr. Alley once helped a Grand Canyon ranger answer a tourist’s question: "Why is the Canyon wider at the top than at the bottom?" The tourist had their own favorite theory. Based on the materials that have been presented to you’ve in this class, what geologically accepted answer would Dr. Alley and the ranger have given the tourist?

A) The river cuts down, and that steepens the walls of the canyon, which fall, topple, slump, creep or flow into the river to be washed away, thus widening the canyon above the river.

B) The canyon is really the same width at the top as at the bottom, but the well-known "optical illusion" of distant things appearing smaller causes it to look as if the canyon is narrowing downward.

C) The bulldozer that made the canyon was wearing out its blade as it dug down.

D) The river used to be much wider because it was not steep, and water spreads out when running slowly (a little tap feeds a big bathtub...); then, as the Rockies were raised, the river steepened and narrowed, so it used to cut a wide canyon and now cuts a narrow one.

E) The river used to be much wider before the desert formed, and so cut a wide canyon, but the river has narrowed as the drying occurred, and now cuts only a narrow canyon

According to Wikipedia, Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).

Grand Canyon is part of the Colorado River Basin,it has layered bands of red rock revealing millions of years of geological history.It towering cliff was craved by the copper-colored Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.

The Canyon is wider at the top than at the bottom because the river (Colorado River and its tributaries) cuts down, and that steepens the walls of the canyon, which fall, topple, slump, creep or flow into the river to be washed away, thus widening the canyon above the river.

Porque el clima de República Dominicana es tropical - cálido? ​
miskamm [114]

Answer:

La República Dominicana, la parte oriental de la isla Hispaniola, tiene un clima tropical, caluroso todo el año, con una temporada más calurosa y bochornosa de mayo a octubre y una estación relativamente fresca de diciembre a marzo, mientras que noviembre y abril son meses intermedios. .

En cuanto a las precipitaciones, a lo largo de las costas este y sur, hay una temporada de lluvias entre finales de abril y octubre, mientras que la costa norte, expuesta a los vientos alisios, es lluviosa durante todo el año, aunque la costa noroeste experimenta una disminución. en lluvias de junio a septiembre.

Las temperaturas en República Dominicana son altas durante todo el año, al menos en las llanuras, sin embargo, durante la temporada de verano, de mayo a octubre, el calor es sofocante, mientras que es más agradable, pero aún un poco húmedo, en invierno.

Debido a los vientos alisios del noreste, que soplan de noviembre a marzo, las laderas orientadas al norte suelen ser más húmedas que las expuestas al sur. Sin embargo, la presencia de cadenas montañosas puede aumentar o disminuir el efecto de los vientos alisios, tanto que algunas áreas tienen un clima muy húmedo y una vegetación exuberante, mientras que otras son casi áridas.

Por ejemplo, en Azua, en la costa de la bahía de Ocoa, sólo caen 640 milímetros (25 pulgadas) de lluvia al año, y menos aún en el lago Enriquillo, cerrado entre las dos Sierras; la costa suroeste de la provincia de Pedernales también es bastante árida. Por el contrario, en Santo Domingo, que se encuentra en la costa sur pero no está protegida por montañas, las precipitaciones ascienden a unos 1.450 mm (57 pulgadas) por año.

En República Dominicana, como ocurre generalmente en el Caribe, las lluvias ocurren principalmente en forma de chubascos cortos y tormentas eléctricas, a veces intensas, que por lo tanto no reducen mucho las horas de sol; además, a menudo se concentran en ciertos períodos, por lo que es posible que no llueva durante toda una semana, incluso en la temporada de lluvias.

De vez en cuando, de diciembre a marzo, el país puede verse afectado por algunos sistemas frontales de Estados Unidos, que pueden traer nubes y lluvias, y también un viento fresco, capaz de bajar algunos grados la temperatura, aunque en un tiempo. De manera menos notoria que en Cuba y Yucatán (México), que están más cerca del continente americano. Sin embargo, en estos casos, la temperatura puede descender por debajo de los 10 ° C (50 ° F) en las zonas montañosas del interior y alrededor del punto de congelación en las montañas.
