An earthquake is measured by its Magnitude and Intensity. The Magnitude indicates the amount of energy released at the source (or epicenter) and is measured by the open-ended Richter Scale. The intensity of an earthquake at a particular locality indicates the violence of earth motion produced there by the earthquake. It is computed with the help of Modified Mercalli Scale (MMS).

Aphelion is the point in the path of a celestial body (as a planet) that is farthest from the sun. Its opposite is Perihelion which is the point on its orbit when the Earth is closest to the sun.

Correct Option: A

Dendritic drainage systems are the most common form of drainage system. The term Dendritic comes from the Latin word "dendron", meaning tree, due to the resemblance of the system to a tree. In a dendritic system there is one main river (like the trunk of a tree), which is joined and formed by many smaller tributary rivers. Dendritic systems form in V-shaped valleys; as a result, the rock types must be impervious and non-porous.

When the glaciers melt, the tributary troughs are left as hanging valleys high on the walls of the main glacial valley. A hanging valley is a tributary valley with the floor at a higher relief than the main channel into which it flows. They are most commonly associated with U-shaped valleys when a tributary glacier flows into a glacier of larger volume.

Latitude is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. The lines of constant latitude, or parallels, run east–west as circles parallel to the equator. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles.
