Answer:
A rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall. Rainforests are Earth's oldest living ecosystems, with some surviving in their present form for at least 70 million years.
Answer:
b. stratigraphically alternating sequences of sandstones, conglomerates, and shales.
Explanation:
It is unlikely that one would find igneous rocks such as basalt and granite in fluvial environments. Coal is also not usually found in fluvial environments. Limestone prefers shallow and calm waters so would not be moved by water normally. This therefore invalidates options a, c, d, e and f.
For the hypothesis to be true, one would need to find conglomerates as these contain large clasts and are present in fluvial environments. Alternating sequences involving conglomerates and sandstones would indeed show that that some floods were able to carry large clasts.
Answer:
High sea surface temperature and High rainfall
Explanation:
<em>El Niño</em> is a pattern of climate that causes the unusual warming of surface waters in the eastern part of the tropical Pacific Ocean. It affects the temperature of the ocean and changes the strength and speed of its currents, coastal fisheries' health, and local weather from South America to Australia and beyond.
It begins when warm water in the western part of the tropical Pacific Ocean moves toward the eastern part of the tropical Pacific Ocean along the equator. Usually, warm water pools near Indonesia and the Philippines, but during <em>El Niño</em>, the warmest water of the Pacific Ocean assembles at the eastern part of the tropical pacific ocean.
Moreover, trade winds weaken in the central and western part of the tropical Pacific Ocean that weaken the upwelling of nutrient-full cold water to cool warm surface water at the eastern tropical Pacific Ocean. This warm surface water of eastern part of tropical Pacific Ocean warms the atmosphere that empowers moisture-rich air to develop into thunderstorms.
In this way <em>El Niño - Southern Oscillation Event </em>causes the rise in temperature of sea surface and high rainfall at eastern part of the tropical Pacific Ocean.
