Answer:
It is rich in fossil fuels and is the world's leading producer of natural gas.
Step-by-step explanation:
Russia is the biggest country in the world, and not just that, but its territory is in a location where it is abundant in natural resources. The most important natural resources for Russia are fossil fuels, and it has an abundance of the two most demanded ones, oil, and natural gas. When it comes to oil, Russia is not the top producer in the world, but it is among the biggest ones, but when it comes to natural gas, it is by far the biggest producer.
These two resources are great to have when taken into consideration that they are highly demanded and at a good price, but it is always dangerous for the economy to rely on so few products as even the smallest oscillation in price or demand can have a huge negative impact. This is why in the past couple of decades Russia has been developing other sectors as well, like agriculture where it is becoming a global force, and timber since it has the largest forest in the world.
