Hello! Polar climate is in North & South Poles, where the weather there is extremely cold. Just by looking at the answer choices alone, A and B are both eliminated, because it is not hot, warm, or humid. Plus, the weather described in those answer choices does not fit at all. D is out as well, because the weather does not vary in the poles. It is very cold year-round. The only answer choice that even makes sense in this problem is C. Therefore, the answer is C.
Answer:
Human activity - Produces greenhouse gasses.
Greenhouse gasses - Cause atmosphere to trap more heat.
Sun's output - Can vary.
Ice age - Peaked 20,000 years ago.
Explanation:
Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.
The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.
The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.
There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.
Answer:
A
Explanation:
The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%.
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.
