Answer:
The Carboniferous era had large deposits of coal matter in the soil. However there was absence of decomposers which gave rise to increased accumulation of organic matter in the soil.
Decomposers make use of oxygen to breathe in the soil due to their existence as animals and not plants. They inhale oxygen and give out Carbon dioxide.
Absence of these decomposers mean increased level of oxygen due to its non usage and reduction in CO2 which is the end product of respiration for the decomposers.
Answer:
the inner core is solid because S-waves stop at the inner core. The strong magnetic field is caused by convection in the liquid outer core.
Explanation:
Answer:
The sun would be mostly visible form that distance.
Explanation:
- Alpha Centauri is the closest star form earth and solar system and it has about 4.37 light-years from the sun and is a triple star system that consists of the A, B, and C centuria. If viewed from the space the sun would be visible in the solar system and the earth and Jupiter as a tiny dot.
The correct answer is B. The Bristol Glacier is older than the Camden Glacier.
Explanation
The formation of glaciers has three stages. The first is the accumulation in which the snow falls in one place and accumulates there and forms the glacier. The second is compaction in which new layers of snow accumulate on top of the first ones, compacting the lower layers. The third is crystallization in which pressure and air cause snow to crystallize into glacial ice. Therefore, the age of a glacier can be known by its length, the older is the longer glacier. According to the above, if the length of the Bristol Glacier is greater than that of the Camden Glacier, it is because it is older. Then the correct answer is B.
C. Energy
Explanation:
Water needs to have enough energy to overcome inertia and gravity during erosion.
Energy is the ability of any body to do work.
Inertia is the tendency of a body to remain at rest or in uniform motion.
Gravity is the force of attraction between the earth and any massive body.
To overcome these forces, a body needs adequate amount of energy. With the energy, the water is able to exercise its eroding power by moving.
