But it deals with the study of insects.A scientific inquiry includes the following steps- Mere observation is made and related questions are asked. It collects the required information and a hypothesis is created. This hypothesis must be tested performing various experiments and lastly, conclusions are needed to be drawn. So experiments should be done but it must be controlled one.Initially, a volcano tends to be an active one because of the significant rise in height due to the upward pressure exerted by the magma. These volcanoes after several episodic volcanic eruptions become dormant that means volcanic eruption has not taken place for a long time, but if magma intrusion is more then it might generate again. In the final stage, it becomes extinct and no more volcanic eruptions take place.Sand dunes are formed due to the erosion and deposition of sediments in a region where there is abundant sands. These are the regions of sand accumulation and it has two sides, the windward slope, and the leeward slope. From the windward slope side, the wind blows and carries sediments towards the leeward side. Whereas loess is the depositional features formed due to the accumulation of sand and silt.A tiltmeter is an instrument often used by the geologists to calculate the vertical displacement of a fault.Thus, the correct answers are given above....
