To differentiate: Temperature and heat.

Answer to Problem 1LC
While temperature defines the “average kinetic energy of the molecules in a substance”, heat is the form of energy that gets transferred from one substance to another due to the difference existing in their temperatures. The heat flows from a hot object to the cold one by raising its internal energy.
Explanation of Solution
The “average kinetic energy” possessed by the molecules of a substance defines its temperature. It may be more precisely the kinetic energy due to the translational motion of the molecules composing a substance. The more vigorous the movement is, the more will be the kinetic energy and the higher will be the temperature of the substance.
The difference in temperature will lead to transmission of energy. This energy transmitted from one object to another is known as heat. Usually, the direction of heat energy transfer will be from a body at higher temperature to the ones at lower temperature. The hotter substance from where the transfer occurs, undergoes a decline in its internal energy, while the cold substance to which the heat energy got transferred experiences a rise in its internal energy.

- For the past 3 million years the earth has experienced glacial-interglacial cycles at regular intervals that coincide with the Milankovitch Cycles. Please briefly describe the three Milankovitch Cycles and their timescales. What is the leading theory for why the timing of glacial-interglacial cycles is connected to these Milankovitch Cycles?arrow_forwardWhy do waterfalls move backwards over time? In your explanation, please use the term “nickpoint”?arrow_forwardThe picture below is of the Kaskawulsh Glacier in Yukon, Canada. What is the name of the type of feature that the red arrows are pointing to in the middle of the glacier and how are these features formed? In your answer please also define the term lateral moraine and how lateral moraines relate to the feature with the red arrows?arrow_forward
- it was stated that one major effect of rivers is to flatten out the continents. How do rivers flatten continents?arrow_forwardThe figure below shows the average change in glacier mass per unit area for various mountainous regions around the world. Why are the globe’s mountain glaciers shrinking? Does glacial melt increase or decrease the amount of water stored on the continents? What are the factors in the continental water budget equation that must change in order to restore equilibrium when glaciers melt ? What is the effect on global sea level?arrow_forwardWhat 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?arrow_forward
- 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?arrow_forwardForest-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?arrow_forwardDraw 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 movementarrow_forward
- 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?arrow_forward1. 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.arrow_forwardOn 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.arrow_forward
