Answer:
remain same
Explanation:
The gravitational force is given by
F= GMm/r²
F= G × 2M×2m/ (2r)²
F= 4GMm/(4r²)
F= GMm/r²
Answer:
C. time for weathering of rock and development of the soil horizons
Explanation:
The primary succession is the initial colonization of a previously existing ecosystem that has been totally destroyed by some disastrous event. During this colonization, the organisms that settle in are ones that do not have any particular requirements for their survival, like the lichens and mosses. As they spread all over the area, they slowly start to influence the rocks on which they have grown, little by little weather them and providing them with organic matter. This gives rise to the first soil horizon, but it is very shallow and the soil is not well formed, so lot of time needs until the soil becomes suitable enough for the secondary succession to occur. When the secondary succession occurs it means that there's soil formed in the area, so new organisms move in, and as they do they replace the ones from the primary succession, slowly forming a new ecosystem and well balanced ecological community.
Answer: Glacier
Definition:
a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles.
Answer:
The atmosphere is heated or cooled by the following processes:
(1) Partial absorption of solar radiation by the atmosphere
(2) Conduction
(3) Terrestrial radiation
(4) Convection and advection
(5) Latent heat of condensation
(6) Expansion and compression of the air.
Answer: Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The plates under the oceans are called oceanic plates and the rest are continental plates.
