Answer:
In the USA it increased. In Europe it decreased.
Explanation:
After World War II the birth rate in the United States saw a substantial increase and the generation was born that is known today as the Baby Boomers. Such was the increase in births in the post-war years of economic prosperity that the population pyramid of the United States is visibly larger in the lines marking those years.
In Europe the situation was different. While birth rates had already been decreasing before the onset of WWII, after the war this trend only continued as the continent rebuilt itself after the second of two very deadly conflicts.
Answer:
If contours are close together it indicates a <u>steep slope</u> and if they are apart it means a relatively gentle or <u>flat slope</u>.
Explanation:
Topographic maps were created to depict the relief features and type of terrain on the map. The use of contour lines drawn on a map is done to show the lines of equal height of elevation. These lines tend to remain constant. Also, there are three types of contour lines on a map i.e the supplementary, Index and Intermediate. The dark brown color is used to show lines of high altitude and light brown lines represent low altitude. The more close the line is the steeper is the wall and the far the lines are less is the compactness and more is the gap.
Answer: True
Explanation: The fact that the Earth's axis is tilted by approximately 23.5 degrees is the reason for the seasons to exist. This means that if one of the Poles of the Earth is, for example, the North Pole, tilted toward the Sun, then the northern hemisphere is summer, and vice versa. Of course, because there are more hours of sunshine in a certain hemisphere at certain times of the year, and then it's summer. In the hemisphere that is not tilted towards the sun at certain times of the year, there are fewer hours of sunshine and there is winter. In addition, there are transitional seasons, spring and autumn, which depend on the specific position of the Earth towards the Sun and the specific place on Earth, for example, not every place on Earth has spring and autumn.
Answer:
Evidences suggested are given below
Explanation:
Evidence given in support of the existence of Pangaea was given in Plate tectonic theory by Alfred Wegener.
1. The Jigsaw fit puzzle
2. Glacial ranges and mountain chains on various continents.
3. Formation and age of rocks, in southern hemispheres
4. Flora and Fauna evidence
- Apart from this poleward moving forces and forces of the sun and the moon gravity and west wind drift have seen to be responsible for the formation of hypotheses.
- As he stated that the continent of South America and Africa were once part of the same Gondwana landmass, Similarly the North America eastern side and Western side of Europe were the same as the ones that were part of the Lurata i.e Northern super landmass. This can be found in the evidence given in the paleomagnetism theory.
- Wegener believed that the continental crust is formed from the slabs and these slab or plates are lighter in weight and float on thick liquid asthenosphere oceanic crust with the help of winds and ocean currents. Thus he concluded that rocks were once part of the supercontinent that broke with the move
