Scientists can't be sure about the early atmosphere and can only draw evidence from other sources. For example, volcanoes release high quantities of carbon dioxide. Iron-based compounds are present in very old rocks that could only have formed if there was little or no oxygen at the time.
The three types of unification that can alter political and economic relationship are Incorporating Federal (or con-federal) union and Mixed unions.
<u>Explanation:</u>
- A political union is a kind of state that is made of smaller states. The process of forming such a state out of smaller states is termed unification.
- The unification of states that used to be unified and that is reuniting is known as reunification.
- Types of unification that can alter political and economic relationships are as follows,
- Incorporating union
- Federal (or confederal) union
- Mixed unions.
Answer:
The altitude, latitude and availability of sunlight and water.
Explanation:
- There are various types of climatic effects that help geographers identify the plant life in a particular place as the altitude, latitude, and duration of sunshine, cloudiness, and amount of rainfall.
- There are certain types of biogeographical realms or ecozones on earth that influence the type of natural vegetation and are governed by their respective climates.
- Therese regions are also called as biomes. These regions are broadly classified by the type of biota and that is dependent on the availability of water and sunlight.
The solar radiation is one of the main factors that shapes the climate all over the globe, so the climate differs with the less or more solar radiation it gets. The polar regions are cold, this is due to the fact that the solar radiation in here is very obscure, because the solar radiation falls at a very wide angle the heat is dispersed over larger area, thus the land gets very little warmth. The Equator, on the other hand, gets direct solar radiation, the sun light falls at a 90 degrees angle or close to it, so the radiation is more concentrated on a smaller area, thus the warming is bigger.
