Answer:
Options (1), (2) and (3)
Explanation:
Alfred Wegener was the person who first invented the continental drift theory. He observed that the continents move from one place to another with respect to a fixed point. He put forward many pieces of evidence but he was unable to explain the main mechanism that is responsible for these motion of continents.
The pieces of evidence that were given by Alfred Wegener supporting the continental drift theory are-
(a) The continents move slowly and continuously from one place to another and the edges of these continents perfectly match with the other.
(b) Similar fossil assemblages were found in currently separated continents.
(c) Similar rock types are also found and suggested that the continents were once all together forming a huge landmass which is known as the Pangaea.
Later this theory was modified into a more simple and universally accepted theory which is commonly known as the Plate tectonic theory.
Hence, the correct answers are options (1), (2) and (3).
The site of the chernobyl nuclear accident in 1986, was at the Chernobyl Nuclear Power Plant, which was located in Ukraine. In terms of cost and casualties, it was the worst nuclear power plant disaster in history.
The answer is Wind
Oceant currents are driven by the circulation of wind above the surface's waters, interacting with evaporation, sinking of water at high latitudes.
The electric distance meter and extensometer are used to measure length between two points and tensile strength respectively.
Electronic distance measurement uses electromagnetic waves such as infrared light while extensometer place the object under stress.
<h3>What is Electronic distance measurement and extensometer?</h3>
Electronic distance measurement and extensometer are tools that can be used to Know the length between two points and tensile strength respectively using different techniques.
The extensometer usually places a sample under stress to determine the length of the material while Electronic distance measurement uses beam of infrared light.

4.6 billion years ago - most likely hydrogen (H2) and helium (He)
probably rich in hydrogen compounds like methane (CH4), ammonia (NH3), hydrogen cyanide (HCN), water (H2O), and formaldehyde (HCHO). Also some N2, CO2 but LITTLE or NO free oxygen.
Molecules of H2 and He move really fast, especially when warm, that they eventually all escaped Earth's gravity and drifted off into space.
