-- If you go outside at the same time every night and look at
some familiar stars, you'll see each of them them move westward
at almost exactly 1 degree per night.
-- The reason for that apparent motion is the real motion of the
Earth in its orbit around the sun, at almost exactly 1 degree in
every 24 hours.
(average during a whole year is 0.9856 degree per day.)
I'm not sure, but wouldn't it be carpet weaving or sewing?
It is the CARPATHIAN MOUNTAIN RANGE.
This 1,500 km-long range stretches west to east in an arc from the Czech Republic to Romania.
It passes through the countries of Czech Republic in the northwest through Slovakia, Poland, Hungary and Ukraine, to Romania and Serbia.
Answer:
Improved agricultural practices have led to increased productivity, decreased organic production, increased health risks, increased water pollution, and increased profits.
Explanation:
Since the turn of the 20th century, agriculture has experienced numerous changes and is much different nowadays than it used to be. This has been due to rapid technological development, which has also improved agricultural practices. The improvements have been in every sphere, from the protection of the plants to create more resistant and plants that have higher productivity, better irrigation, mechanization, bioengineering, and at the end of it all it has led to higher profits.
The developments in genetics have led to the creation of plants that are more resistant to diseases and have higher productivity. The pesticides, herbicides, and fungicides have all helped in the protection of the pants and destruction of pests, which further led to an increase in production, but their usage has also led to pollution of the soil and water. Unfortunately, the usage of chamicals has led to increased health risks, and significantly lowering the organic production which was dominating before.
Answer:
Oceans = > 97 percent of Earth's water.
Glaciers = > 70% of Earth's freshwater
River = > Powered by gravity
Groundwater = > 100 times more water than all rivers and lakes
97% of the water on Earth is not drinkable as it is salt-water in oceans.
Of the 3% that is freshwater, Glaciers make up about 70% which means that we don't have access to a significant amount of freshwater either.
Of the available freshwater to us, groundwater comprises 98% which enables it to be 100 times more than all rivers and lakes.
Rivers are powered by gravity in that they flow from areas of higher elevation to areas of lower elevation as gravity pulls it downwards.
