Answer: They are younger than the Appalachian mountains
They are taller than the Appalachian mountains
Explanation:
The Appalachian mountains highest peak is about 6,684 feet while the Rocky mountains highest peak is 14,440 feet
The Appalachian mountains are 480 million years old while the Rocky mountains are only about 300 million years old
To be frank, I don't think your question is specific enough, but I would say that the answer would be the Rocky mountains, or just mountains. those are the only major kinds of landforms I can think of
because they're different ways
South Asia is a really difficult place to try and centralize the countries. A big problem are the large populations in the countries, with the likes of India, Pakistan, and Bangladesh all being in one of the most populated countries in the world, so centralizing them would mean that hundreds of millions of people will either live on the verge of existence (even worse than it is now), or will be moving towards the city where the centralization will be taking place, and there's no such place that can function properly if that amount of people flood in it. Another problem is that there's multiple cities that are very big, with millions of people living in them, and if centralization takes place, they will start to decline in every aspect, and that will cause huge problems of all sorts on national level.
The correct answer is (c.) troposphere
The troposphere is the lowest portion of the atmosphere but also it is where most gas particles are located. It holds 75 percent of the atmosphere's mass. It is typically a hundred meters deep to 2 km. Above the troposphere is the tropopause, bordering between troposphere and the stratosphere.
