False, herodotus was not the founder of modern geography
Answer: C. The overall temperature of the Earth will increase.
Explanation:
Let's begin by explaining that Earth has a layer, the atmosphere, that is almost transparent to solar radiation, which is composed mainly of shortwave radiation (ultraviolet (UV) and visible light). Then, this layer allows to pass most of the sunlight (visible light and a small part of the UV radiation), without being absorbed.
When this radiation reaches the Earth, it is absorbed by the water 
), soil, plants, animals; well, everything that inhabits and also the buildings. Once this absorption process ends, the light turns into long wave (IR) radiation, generating heat that is then released into outer space and known as albedo.
However, due to climate change (caused by the humankind), the Earth now tends to absorb more energy than it emits to the space as IR radiation. If this process is mantained for a long term, the planet's global temperature will highly increase.
The reasons as to why the Indo-Europeans migrated to Europe were the better climate conditions, more grazing land and fertile soil, and overpopulation.
Explanation:
The Indo-Europeans were a group of people that formed and lived in the Eurasian Steppes, mostly in the lowlands of what is now Central Asia. Central Asia though was not offering the best living conditions, as the climate was harsh, fertile soil, was lacking, the grazing lands were limited, and the population of the Indo-Europeans was constantly growing. This made numerous groups of these people to migrate in several waves toward other regions, including Europe.
Being a war-like people and superior in combat, the Indo-Europeans found it easy to move into the European territories and settle in. The migration waves were mostly going through the lowlands north of the Black Sea, and through Anatolia and the Balkan Peninsula. Very quickly the Indo-Europeans managed to become dominant in Europe, establish their culture, language, and beliefs.
The main reason for migration were:
- overpopulation
- better grazing lands
- fertile soil
- better climate
Ethnic families that are believed to have originated from the Indo-Europeans are:
- Celtic people
- Germanic people
- Slavic people
- Baltic people
- Italic people
- Daco-Thracian people
- Illirian people etc.
