These blades are rigid and move in three different directions at different intervals.
- Abhisari
- Divergent
- Evolution
The movement of the blades with each other causes a condition called horizontal resolution error.

Small blades
- Indian
- Arabic
- Management Caribbean
- Nazca off the west coast of South America
- Scotia in the South Atlantic Ocean
Ground discs
- The Australian and Indian planes were connected between 50-55 million years ago.
- The fastest moving ocean planes are the Cocos plane at 75 mm per year and the Pacific plate at 52-69 mm per year.
- At the other end of the spectrum, the Eurasian plane is the least moving plane, moving at 21mm per year.
Earth's atmosphere
- The layer of air around the earth The Earth's atmosphere is the layer of air around the earth. It stays close to the earth due to the force of gravity.
- This atmosphere protects life on Earth by absorbing harmful rays, such as ultraviolet light from the sun, and by reducing the temperature day and night.
- From the atmosphere ¾ is from the surface of the planetary. Is within 11.
- Km from the United States. People flying at an altitude of 80.5 (50 cm) are called astronauts. Km At re-entry to the 120 (75 cm or 400,000 ft) limit, the effects of the atmosphere are visible.
- Km from the ground. At an altitude of about 100 m (62 s, or 328,000 ft), the Karman line is considered to be the boundary between the atmosphere and the aliens.
Pressure and density
- The average atmospheric pressure at sea level is 101.3 kPa (14.7px).
- Total atmospheric mass in kg. 5.136 x 108 only.
- The total weight of the air above the point where the pressure is measured is a direct result of the amount of air load.
- This means that the air pressure varies with location and time.
Radiation balance of the Earth
- The Earth's radiation equilibrium is the equilibrium of heat rays reaching the Earth and leaving the Earth.
- The rays that fall to the ground are shortwave. (Short wave) Accordingly, the following equation is the short wave equilibrium (Q2). Qs = G - R = D H - R or the ratio (Albedo) = G (1-a)
- D = direct rays H = scattering rays
- G = Earth radiation
- R = return of rays from the earth
- a = ratio
The earth's atmosphere and atmosphere emit heat rays. This causes an overlap with the sun's rays. These are long waves (q1)
- AE = effective rays
- AO = rays coming from the earth's surface
- Q1 = AE = AO - AG
- AG = greenhouse effect
- The total energy can be measured using the two equations mentioned above.
- Qt = Qs - Q1 = G - R- AE
- External factors are sunlight. It has been found that 25% of the sun's average radiation is spent on production.
