Answer: East to West
Explanation:
A Roche Moutonnée is a rocky mass formed by abrasion when a glacier passes over a bedrock. The glacier moves from the east to the west, creating different slopes on each side of the Roche Moutonnée. this is due to different processes o each side. When the glacier travels up the bedrock, it smoothens the edges, creating rounded tips. On the downward journey, melted ice from the glacier leaks into the rocks. On refreezing, the ice creates cracks in the rock and breaks away parts of the rock.
<h3>Peruvian adaptations to their physical environment</h3>
Explanation:
The Peruvians adapted to their natural environment of high altitude mountains like the Andes. The mountains created environmental challenges like low temperature, decreased precipitation, poor thin soil etc.
The Peruvians utilized the mountains in the most sustainable and efficient way both for agriculture as well as irrigation purposes. They followed terrace agriculture along the high mountain regions and built aqueducts to supply water for drinking and irrigation.
The agricultural terraces were constructed in such a way it received a good amount of sunlight even though sunlight was blocked by the surrounding high mountains. The crops were spaced widely to ensure proper sunlight and crop growth.
The irrigation system through aqueducts was constructed to prevent flooding.
The achievements of the Tang and Song Dynasties include "the invention of gunpowder and the growth of Confucianism".
The Song dynasty (960-1279) takes after the Tang (618-906) and the two together constitute what is regularly called "China's Golden Age."
The utilization of paper cash, the presentation of tea drinking, and the innovations of gun powder, the compass, and printing all happen under the Song. (The way that the tradition traverses the year 1000 may make it simpler for students to find these advancements in time.)
