Chapter 18, Problem 1GST

To determine

The sequence of formation of features present in the accompanying image showing metamorphic rock gneiss, a basaltic dike and a fault with logic.

Expert Solution & Answer

Answer to Problem 1GST

The sequence of formation of features present in the image from older to younger is Gneiss, dike, fault. Gneiss must have formed before the intrusive dike, in order for it to cut through gniess. Because the fault offsets the dike, the fault occurred after the intrusion of dike. This is an application of the principle of cross-cutting relationships.

Explanation of Solution

“Principle of cross-cutting relationships states that the geological feature which cuts across strata is always younger than the one it cuts through it” A fault is a break or fracture in the rock, along which the displacement occurs.

According to the principle of cross-cutting relationship, the igneous dike is younger and formed after the metamorphic rock Gneiss that cuts through it. Gneiss is a high grade foliated metamorphic rock and must have formed before the dike, otherwise the dike would have been metamorphosed too. The fault has split and separated the dike, hence the igneous dike must have formed before the fault occurred.

1. Globally, from which source does more water evaporate into the atmosphere: oceans or land? 2. Approximately what percentage of the total water evaporated into the atmosphere comes from the oceans?Percentage from oceans = Ocean evaporation/Total evaporation × 100% = _____ % 3. Notice in Figure 8.1 that more water evaporates from the oceans than is returned directly by precipitation. If sea level is not dropping, identify a source of water for the oceans in addition to precipitation. 4. Worldwide, about how much of the precipitation that falls on the land becomes runoff: 35, 55, or 75 percent? 5. Much of the water that falls on land does not immediately return to the ocean via runoff. Instead, it is temporarily stored in reservoirs such as lakes. In some mountainous and polar regions, what features serve as reservoirs to temporarily store water?
