Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods.
Decomposer and scavengers
Answer:
1. giant impact forms moon
2. end of heavy bombardment
3. early life (based on fossil evidence))
4. oxygen buildup in atmosphere
5. earliest mammals
6. dinosaurs go extinct
7. earliest humans
Explanation:
The Earth has a very interesting past, with lot of changes and turnarounds in it. If we sum it up quickly, we can say that soon after the Earth formed and collided with another large space object, part of the Earth was torn away, which eventually formed the moon. The Earth was constantly bombarded by meteorites and asteroids, but that came to an end as the atmosphere was becoming denser and denser. The first life started to develop in the oceans in the form of cyanobacteria, which used photosynthesis, and were constantly releasing oxygen, building it up int he atmosphere. The oxygen changed the living conditions, enabling the life to thrive and diversify. The dinosaurs and mammals eventually came on the scene, with the dinosaurs coming first by around 20 million years, giving them the edge to become the dominant life form. The mammals lived in the shadows until the dinosaurs existed, but their reign ended with a large meteorite collision. This prompted the quick evolution and diversification of the mammals, quickly becoming the dominant life form, and just few million years ago they gave rise to the earliest human ancestors, the hominids.
Answer:
Because of its rivers and topography containing Big rivers with hydroelectric potential
Explanation:
Summed up Hydroelectric power is obtained by the water flow moving turbines that generate electric power. This water is obtained from rivers with a high flow generally near mountainous regions, this kind of rivers is all over Europe because of its topography, the Alps and the Ural mountains are home of many hydroelectric plants taking advantage of the rivers flowing down. For example in Austria, the Danube River is used for obtaining Hydroelectric power.
Although the Hydroelectric plants are smaller compared to Asian or Canadian plants, hydroelectric power is still one of the main sources of energy for central Europe, countries like Spain, France, Netherlands, Sweden, Austria take advantage of their mountains and rivers running down them for building the hydroelectric plants.
