Answer:
The geography of Ancient China shaped the way the civilization and culture developed. The large land was isolated from much of the rest of the world by dry deserts to the north and west, the Pacific Ocean to the east, and impassable mountains to the south. This enabled the Chinese to develop independently from other world civilizations.
Explanation:
I'm assuming you meant subsistence farming? If so then yes, it would be a large problem because they would then not have enough food to feed themselves.
Answer:
Air molecules scatter blue light more efficiently than other colors.
Explanation:
The sunlight has many colors and each of them has a different wavelenght. The color blue has shorter wavelengths and higher frequencies than the other colors. So, as sunlight goes through the air, the blue part causes charged particles to oscillate faster than the red part does and it is scattered more efficiently than the other colors and that's the reason for the sky to be blue.
Answer:
prohibits the introduction of invasive species
controls the kind of waste and pollutants allowed
assesses human influence on the environment
designates protected zones on the continent
Explanation:
These four key terms are some of what the Madrid Protocol includes.
Prohibiting the introduction of invasive species keeps the ecosystem from being dominated and/or destroyed by a single species that the ecosystem is not built to handle.
Controlling the kind of waste and pollutants allowed on the continent ensures that the environment remains stable without the influence of outside chemicals, such as oil or carbon emissions that could harm the ecosystems.
Assessing human influence on the environment keeps track who does what and how they do it, essentially preventing extreme human action from being taken so as to preserve Antarctica's natural order.
Designating protected zones on the continent that can only be accessed with special permits ensures that only people who require access for research or whatnot, or more simply, qualified personnel, are able to enter these zones, so as to keep contact down to a minimum and further preserve Antarctica's natural environment.
B. The continents on a map looked like they fit together.
A is the theory he proposed <em>after</em> making this observation
C and D would disprove his theory, not support it.
