Answer:
Options (1), (3), (4), and (5)
Explanation:
The mass movement is often referred to as the downslope movement of materials such as rock particles, soil and sand under the influence of gravity. The factors that are responsible for the mass movement are gravity, steepening of the slope, lack of vegetation cover, oversaturation of soil or materials. They can also occur during an earthquake as the ground shakes. These mass wasting is also considered as the mass wasting process.
This mass wasting process occurs in the following ways-
(1) Falls
(2) Slides
(3) Creeps
(4) Flows
Thus, the correct answers are options (1), (3), (4), and (5).

Answer:
A. Plains
Explanation:
Plateaus are high plains or "tablelands" meaning they are elevated. Mountains are also generally elevated environments. By process of elimination, the answer is plains. However, we can prove this by looking at the definition of a plain; it is as follows:
"A large area of flat land with few trees."
Its synonyms include words like "lowland"
Answer:
Option (C)
Explanation:
The mid-oceanic ridges are the submarine mountains that are formed in a divergent plate boundary. In this region, the oceanic crust gradually rises due to the movement of the magma towards the surface. This movement of magma upward is due to the formation of convection current in the mantle, where these currents are generated because of the heat energy provided from the interior of the earth.
These are the region, where the temperature is extremely high and the rocks are in the form of liquid (magma) and hot rocks are less denser than the cold rocks, so they move upward. This motion of magma upward and erupting on the seafloor leads to the uprising of the oceanic crust.
Thus, the correct answer is option (C).
