2. One limb lies over the other in a horizontal direction.

E) Isoclinal:

1. The limbs slope in the same direction with the same amount.
2. The axial plane may be vertical, inclined, or horizontal.
3. The slope of some portion of limbs is near vertical.

Choose the correct option by identifying the correct correlation in the sentence:

Water or snow enters the cracks in the rocks and makes it weak. When the glacier passes on these rocks, it pulls the rocks at the bottom along with it. This process is called ________.

Assertion A: Intensity of an earthquake is a measurement of the energy released during an earthquake.

Reasoning R: Mercallis scale is used to measure the intensity of an earthquake.  

Identify the correct correlation:
A: Assertion; R: Reasoning

A: South-East Asia, Japan, and islands in the Pacific Ocean are most vulnerable to earthquakes and volcanic eruptions.
R: They are located in the 'Ring of Fire'.

Identify the correct group:
