Answer:

Option b

Explanation:

In the year 1912, a meteorologist and a geophysicist, proposed a theory that explained positional shifts in the continents on the surface of the Earth.

Likewise, he also clarified why similarity in appearance exist between the fossils of animals and plants and comparable rock developments are found on various continents.

Alfred Wegener proposed that maybe the Earth's rotation made the continents move towards and separate from one another or crerated continental drift. (It doesn't.) Today, we realize that the continents lay on monstrous sections of rocks called tectonic plates.  

The plates are continually moving and connecting in a procedure called plate tectonics.

Please 1) describe what is meant by the terms short-wave and long-wave energy, 2) name a specific type of electromagnetic energy
Studentka2010 [4]

Answer:

  1. wavelength difference
  2. ultraviolet, infrared
  3. shortwave = Sun; longwave = Earth

Explanation:

  1. The terms shortwave and longwave radiation refer to the wavelength of the radiation, which is the distance from the crest of one wave to the crest of another. The wavelength reflects the energy of the wave. Longwave radiation is less energetic, while shortwave has more energy. Longwave radiation has even longer wavelengths than red light in the visible spectrum, while ultraviolet radiation has wavelengths shorter even than the shortest violet visible light.
  2. Ultraviolet is not the only kind of shortwave radiation; in fact, it is the shortwave radiation closest to visible light on the electromagnetic spectrum. X rays and gamma rays have far shorter wavelengths and thus are more energetic. Infrared radiation is the type of the longwave radiation that is closest to the visible spectrum. Radiation with much longer wavelengths than infrared light include microwaves and radio waves.
  3. The Sun produces its own radiation since it is a body that is much more massive and with a much higher temperature than the Earth. Because of this, the radiation emitted from the Sun is mostly shortwave radiation. The Earth emits radiation as well, but it is infrared radiation emitted in the form of heat that is not visible to human eyes.

Why were the Russian peoples largely a “slave” population until 1917?
faltersainse [42]
This was due to the Czar Nicholas II, who led more of a dictatorship. In 1917, people rebelled, so the Czar stepped down.

Cyclonic rainfall and its features​
Zinaida [17]

Answer:

This occurs due to the convergence of different air masses with different temperatures, density, and humidity. The turbulent conditions are produced, and cyclonic rain occurs along the fronts of the cyclone. The layer separating them is known as a front. The front has two parts – the warm front and the cold front.

At the warm front, the lighter warm air that is less dense usually forced to rise over denser cold air and thereby leading to cyclonic rain. A variety of clouds get formed, and they generally lead to moderate to heavy rainfall.

Causes for Occurrence of Frontal Rainfall

A tropical warm air mass comes in contact with a cold air mass of polar region. The less-dense, lighter warm air is then forced to rise over the denser, cold air.

It causes warm air to become cold. As the warm air is forced to rise further, it condenses to form the stratus cloud.

After becoming saturated, the stratus cloud begins to precipitate.

Frontal or cyclonic rain falls gradually for a few hours which can also extend up to a few days.

It is prevalent in Britain and Ireland, which is associated with the movement of depressions over the country. In north-west Europe, warm oceanic air and cold continental air converge to produce heavy rainfall in adjacent areas.
