Explanation

The main factor determining a region's climate is latitude.

The elements affecting the climate are

latitude, altitude and pressure and winds, distance from the sea (continentality), ocean currents, and relief features.

Latitude and altitude: The most important climatic control is latitude. Latitude affects the temperature of a place

Explanation

The propagation of radio signals is greatly influenced by the ionosphere.

Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in a vacuum, or into various parts of the atmosphere.

Propagation of these high-frequency waves over short distances is therefore strongly influenced by

the buildings, trees, and terrain in the vicinity of, and between, the transmitter and receiver.

The blue colour of the sky is due to the scattering of light by the atmospheric particles.

Light of shorter wavelengths scatters more than the light of longer wavelengths and

the violet colour has a shorter wavelength, but our eyes are more sensitive to blue light. Hence, the colour of a clear sky is blue.
