the answer is A. they are using alliteration. Look at the use of the letter F in the text.
The study of geography helps educate people on preserving the climate.
For example , we learn about how deforestation affects the quality of the water, and leads to loosened soil. We learn that we need plants to purify our water.
Deforestation also means lesser plants to give out oxygen and as a result increase global warming, creating extreme changes to climates. This can create droughts and famine and affect food production for the community.
The main reason why the tectonic plates move is the conversational currents. There is magma between the upper mantle and the asthenosphere that heats up at the upper mantle. The weight is so small that the magma rises with the help of these conversational currents. When the magma has ascended towards the asthenosphere, it has nowhere to go so the magma lies along the asthenosphere. There the magma cools down again because the asthenosphere is colder than the upper mantle, which makes the magma heavier and goes back down to the upper mantle, where the magma heats up again and everything starts all over again and so it goes on over and over again. Scientists have concluded that the earth's gravity causes two other processes that also cause the tectonic plates to move.
Ridge push - in the spreading zones, the sides of the tiles are raised and slide to the side as in a slide.
Slab pull - when a plate is pulled down by gravity in a subduction zone like an anchor.
Answer:
twice as long
Explanation:
If Stardust managed to cover 50 miles on his first trip to the forest, and later managed to cover 300 miles by going 3 times faster, then we can easily come to the result as to how much more time Stardust needed comparably between the two trips, just by using these three numbers.
If Stardust was going 3 times as fast on the second trip, then we need to multiple that number with the number of miles of the first trip:
50 x 3 = 150
This means that Stardust managed to cover 150 miles on the second trip in the same amount of time as the 50 miles in the first trip. In order to see how much more time Stardust needed to cover the 300 miles, we just need to divide the total amount of miles, with the 150 miles of the 3 times faster speed:
300 / 150 = 2
So we get a result of 2, meaning that Stardust needed twice more time to cover the 300 miles, than what he needed to cover the 50 miles of the first trip.
