Q:

A cavern is an underground chamber formed by

A) Erosion B) Runoff
C) Deposition D) Evaporation
 
Answer & Explanation Answer: A) Erosion

Explanation:

Caverns are openings in the ground. Some famous caverns in the United States are Mammoth Cave, Carlsbad Caverns, Wind Cave, and Luray Caverns.

 

When rainwater trickles down through the soil, it carries carbon dioxide from the air with it. This turns acidic as it moves through the soil, joining with carbon from decaying plants. This acidic rainwater then eats away at, or erodes, the rock under the ground, forming a cave or cavern. For this process to occur, the rock must be the right type; limestone, dolomite, and gypsum are common.

Q:

The Kinetic energy of gas molecules

A) is unaffected by temperature variations B) decreases with increase of temperature
C) increases with decrease of temperature D) increases with increase of temperature
 
Answer & Explanation Answer: D) increases with increase of temperature

Explanation:

Kinetic Energy K.E = 12mV2  or 

K.E ∝V2, Where 'm' is the mass and 'v' is the velocity of molecules.

 

Velocity is proportional to temperature. Hence, KE is proportional to temperature and would increase with temperature.
