Answer:
Ridge and valley landscapes are created by the<u> tectonic movements of the tectonic plates.</u>
Explanation:
The lithosphere is a rigid outermost shell of the Earth. This lithosphere is broken into<u> tectonic plates.</u> The large scale movements of the tectonic plates result in the formation of topographic features like<u> the mountains, volcanoes, valleys, ridges and oceanic trenches. </u>
Therefore, if the tectonic plates are moving away from each other and create a split, it leads to the formation of a<u> valley</u>. Other environmental factors that can facilitate the formation of a valley are climatic weathering, water, wind erosion etc.
The formation of<u> ridges</u> generally occurs due to tectonic deformation driven by subduction zones, thrust faults, etc. Ridges can also be formed by the tectonic deformation caused by magma present in the deeper layers of the Earth. As, the magma pushes the two plates away, a ridge is formed.
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.
Answer: 53
Explanation:
That's only if you're talking about absolute value though. Sorry if that's the wrong answer.
