What is continental precipitation recycling ?Using the concept of precipitation, please explain why changes in landcover in one place can feed back to impact the climate not only in the area where the landcover change occurred but also in other regions?

In the western United States, does severe forest fire tend to increase or decrease streamflow? What are the two main reasons hypothesized to cause this  effect?

Forest-fire sizes in the western US have grown rapidly in recent decades. made the case that this was not due to increased human population and resultant human-caused ignitions. What was the main evidence for this?

Draw a cross section with a tree growing out of Earth’s surface (so I know which side is the surface). Add a dipping joint and label the hanging wall and footwall blocks. Draw a second cross section (again with a tree on the surface of the Earth) that shows how Earth’s surface would be offset along this joint if it turned into a normal fault. Label the hanging wall and footwall and use arrows to indicate the motion of the hanging wall relative to the footwall. Now draw a third cross section with all the same elements as in parts A and B, but for a trust/reverse fault.  Imagine the same cross section either in three dimensions, or in a bird’s-eye view from top down. Draw what this area would look like after a right-lateral strike-slip fault. Label the strike of the fault and use arrows to show directions of movement

Examine the strike and dip of the rock units on the Devil's Fence geologic map in Figure 6.21. Draw multiple large arrows on the map, pointing in the direction of dip on several rock units. Do the rock layers located near the center of the map in Section 14 dip toward the northwest or southeast? The same rocks in Section 14 are also found in Section 18. Do the rocks in Section 18 dip toward the east or west? What is the approximate angle of dip of the units in Section 18?

1. Draw a dashed line representing the hinge line of the large geologic structure that occupies most of the map. Label the hinge line. 2. Are the rocks getting older or younger farther from the hinge line? 3. Is this geologic structure a plunging anticline or syncline? 4. Provide two lines of evidence that support your answer to Question 8.

On the map in Figure 6.21, write the word oldest where the oldest sedimentary rock unit is exposed at the sur-face and the word youngest where the youngest sedimentary rocks occur.

Discussion Question: Glacial (or Ice) and Periglacial Landscapes A+ The Ice and Glaciers chapter focuses on the Cryosphere, the ice on our planet. I always find it interesting to consider the Earth's Hydrologic Cycle, our water in all of the different phases: solid ice, liquid water, and water vapor (a gas). In place number one for the majority of the World's water, we have the oceans. In place number two, we have ice. Neither one is available to us for drinking water at this point. Amazingly enough, in place number three is groundwater before lakes and streams. Water has led to many problems in the history of California, the United States, and even the world.
