I would say that the Rocky Mts were the youngest of all these mountain ranges as they were created between 80-55 million years ago during the Laramide Orogeny and also they are generally much taller than the other mountain ranges mentioned here which is a characteristic of young mountain ranges and their features are sharper as they haven't been eroded the way most of these others have so have been subject to erosion for less time than the others.
35 because 105 divided by 3 is 35
<u>Answer:</u>
<u>The Continental drift</u> is the displacement of continental masses relative to each other. This hypothesis was developed in 1912 by Alfred Wegener, who affirmed <u>that thousands of years ago there was a single and unique supercontinent, called </u><u>Pangea</u><u>, which later became separated.
</u>
His formulations were based mainly on the way in which the forms of the continents seem to fit on each side of the Atlantic Ocean, such as Africa and South America. He also took into account the distribution of certain fossils that coincided in continents far from each other.
<h2>
At first this approach was discarded by most of his colleagues, because <u>
his theory lacked a logical and geological explanation for its epoch. </u></h2><h2>
</h2>
He proposed that the continents move on another denser layer of the Earth that made up the ocean floor. But it was not until the 1960s, with the development of the theory of tectonic plates, that the movement of the continents could be adequately explained.
Answer:
Option D.
Explanation:
Wind, geothermal, biomass, is the right answer.
Renewable energy is the energy which is obtained from renewable supplies, that are normally renewed on a personal timescale, like wind, sunlight, tides, rain, waves, and geothermal energy. Electricity generation, water and air heating/cooling, rural energy services and transportation, are the four main areas for which renewable energy usually provides energy. According to the question, geothermal, wind, solar and biomass are exceeding hydro-power as the predominant modes of renewable electricity.
