Answer: In geography, a plain is a flat, sweeping landmass that generally does not change much in elevation. Plains occur as lowlands along valleys or on the doorsteps of mountains, as coastal plains, and as plateaus or uplands.
In a valley, a plain is enclosed on two sides, but in other cases a plain may be delineated by a complete or partial ring of hills, by mountains, or by cliffs. Where a geological region contains more than one plain, they may be connected by a pass (sometimes termed a gap). Coastal plains would mostly rise from sea level until they run into elevated features such as mountains or plateaus.
Plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world's land area. Plains may have been formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains. Plains would generally be under the grassland (temperate or subtropical), steppe (semi-arid), savannah (tropical) or tundra (polar) biomes. In a few instances, deserts and rainforests can also be plains.
Plains in many areas are important for agriculture because where the soils were deposited as sediments they may be deep and fertile, and the flatness facilitates mechanization of crop production; or because they support grasslands which provide good grazing for livestock.

Answer:
a. meteoroid, meteor, meteorite
Explanation:
The meteoroid, meteor, and meteorite, are terms that very often are mistaken and are used for a single thing, but in practice they are different, despite having the same basis.
All three, as mentioned, have the same basis, they are the same body, just that the differences occur because of the processes through which the space body goes through.
The meteoroid is a term used for the space body while it freely floats into the interstellar space. The meteor is a term used for when the space body enters the Earth's atmosphere and burns, which can actually be seen in the night sky easily. The meteorite is a term that is used for the piece of the space body that managed to reach the surface of the Earth, but more often than not they burn totally and fall apart while passing through the atmosphere, so the meteorites are much rarer than the previous two.
