Step-by-step explanation:
1) A mixed economic system protects private property and allows a level of economic freedom in the use of capital, but also allows for governments to interfere in economic activities to achieve social aims.
2) Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
3) there is a lot of rivers and lakes, with a small population, it is also hot. I would be using the process of water mapping geography.
