Question

__ is a 1.2 ma to 12,500 year cinder cone and lava fall on north rim of Grand Canyon:

a. Wotan's Throne
b. Vishnu Temple
c. Vulcan's Throne
d. Zoroaster Temple

Answer 1

Wotan's Throne is a 1.2 ma to 12,500 year cinder cone and lava fall on the north rim of the Grand Canyon.

Step-by-step explanation:

The 1.2 ma (million years old) to 12,500 year cinder cone and lava fall on the north rim of the Grand Canyon is called Wotan's Throne.

This information is derived from the fact that the Vishnu Schist, which is the basement rock of the Grand Canyon, is over 1.7 billion years old according to Figure 12.

Therefore, the 1.2 ma to 12,500 year cinder cone and lava fall on the north rim of the Grand Canyon is not part of the Vishnu Group, but rather is named Wotan's Throne.
