The correct answer is - B. Slope of the land.
The watersheds are defined by the slopes. They can be small, medium sized, or very large. All parts of the land on planet Earth belong to one watershed or another.
The watersheds have boundaries, and those boundaries are along the highest points of the mountains or the hills. In most cases, one of the slopes of the mountain or hill is in one watershed, while the other one is in another watershed.
The water from the watershed goes into a single place as its final destination. The water can run down the slope on the ground after a heavy rainfall, get into smaller streams and rivers, get directly into a bigger river, but in the end all of that water will get to the biggest water body in the watershed.
Answer: b. Asteroids can cause great damage if they collide with Earth.
Explanation:
The main idea is that asteroids can cause great damage to earth if they collide with our planet. This is what the entire article was centred around starting with an example of the effects of the last time there was a collision with Earth.
It then goes forward to talk about the chances of being hit by another asteroid and what scientists will do if the Earth is at risk of being hit by one which shows that the whole point of the article is the damage asteroids can cause on earth and why this should be avoided.
