Question
Chapter 4, Problem 1GST
To determine
To describe: Whether all the crystals in an intrusive igneous rock are of same size.
Expert Solution & Answer
Answer to Problem 1GST
The crystallization temperature of each mineral is different. So the early formed minerals will have more time to grow larger than the late formed minerals and thereby the crystals in an intrusive igneous rock exhibits different grain size.
Explanation of Solution
The rocks which are formed by the intrusive activity of magma are termed as intrusive igneous rock. Depending on the rate of crystallization of magma the size of the crystal varies. When slow cooling occurs, the ions present in magma are able to move larger distance. Hence larger crystals that are very few in number are formed.
When rapid cooling occurs, the ions in magma will have lose the ability to move. As a result, they combine with each other and forms small intergrown crystals.

C) active layer
D) discontinuous permafrost
Use the attached piezometer map to make your own, clean version of the map, and indicate the elevation of the water table at all piezometer locations.
Draw equipotential lines (lines of equal water table elevation) using regular intervals – creating a contoured map of the water table.
Determine the direction of groundwater flow based on the horizontal gradient. Label the areas of recharge and discharge directly on your map.
Flow lines: Draw flow lines on your water table map. The lines should be at right angles to the equipotential lines and extend from the recharge area to the discharge area.
Hydraulic Gradient, Specific Discharge (Darcy Flux), Average Linear Velocity:
Using your water table map, estimate an average hydraulic gradient between two locations, call them locations A and B, one at the eastern-most and a second at the western-most extent of your dataset (note the north arrow on the map).
Calculate the specific discharge, q, between the two locations. For this calculation…

Q in (L/day)
Q out (L/day)
Residence time (days)
