Answer:
tornadoes are formed by mixing cold and hot air together.
Explanation:
Because hot air rises, when hot air from the west, clashes with cold from the east (or visa versa) the hot air rises above the cold air and causes drag on the inside of the cold air, which makes the inside of the cold air travel at a slower rate than the outside of the cold air, which in turn makes the cold air turn in on itself.
because the cold air turns in on itself, any warmer air underneath rises above the swirl of cold air forcing it to sink to earths level. "friction" or "resistance" between the swirl of cold air and the earth's surface creates more energy that is absorbed by the cold air molecules in the swirl of air, allowing the particles to move quicker and quicker in the direction they are travelling in (a bend or circle), creating a tornado.
MEDC stand for more economically developed countries while LEDC stand for less economically developed countries. Basically, both refer to the wealth and economy of a country and can be defined by factors such as
birth rate
death rate
GNP
Natural Increase
life expectancy
people per doctor or health care
Literacy level
housing
Judging by the above factors, China can be classified as an MEDC country because it has a Low birth rate of 12.17 per 1000 births, a low death rate of 7.44 deaths/1000 population, GNP of 98,909 USD as at 2014. MEDC countries have a GNP of more than 10,000 USD. China has a life expectancy of 75.2 which is considered high and which characterizes MEDC countries. China has also grown to have a high literacy level due to easy access to or free education, adequate decent housing as well as easy access to proper medical care.
Star clusters are groups of stars which are gravitation-ally bound. Two distinct types of star cluster can be distinguished: globular clusters are tight groups of hundreds of thousands of very old stars, while open clusters generally contain less than a few hundred members, and are often very young.
Binary system: a system in which information can be expressed by combinations of the digits 0 and 1. to represent codes and data. Since zeros and ones can be easily represented by two voltages, the binary system is the foundation on which digital technology is built. Every digital computer whether a pocket calculator or a mainframe uses the same binary notation.
