Some of the factors that hinder the improvement of water quality in Eastern Europe are:
-outdated infrastructure. Many places still have very old infrastructure, which was built during the Soviet times
-cost: Eastern Europe is much poorer than Western Europe and therefore does not have the money to invest in infrastructure and in the cleaning of the water
Zebra mussels, hydrilla, and European starling are some invasive species found in the United States
The physical systems of the earth include the lithosphere, the hydrosphere, the atmosphere and the biosphere.
The hydrosphere consists of the earth's water. Approximately 70% of the earth's surface is water. It is found in oceans, lakes, rivers ponds, ice and ground water.
The Lithosphere consists of the solid surface that covers the Earth. Features such as hills, mountains, plateaus, plains and ocean basins are land forms covering the lithosphere.
The atmosphere consists of the thin layer of gases that surround the earth and rises up to 100 miles from the earth's surface, beyond which is outer space.
The biosphere consists of all things living on the surface of the earth and includes animals and plants.
Answer:
B
. Areas near the equator get more direct sunlight so the temperatures are higher.
Explanation:
At equator, the sun is always over head and hits the surface directly. The surface is no at an angle to the sun.
The insolation here is very great and they received more direct sunlight.
- Due to the high insolation, the temperature is higher than most part of the earth.
- Rainfall levels are also high as rain cloud easily forms here.
- In most equatorial region, both temperature and rainfall is high all year round.
Answer:
m<DEF = 90⁰
Each angle of the square is equal to 90⁰
