I’m a little confused about the different levels of preservation.What is the difference between a National Wildlife Refuge and a National Wilderness Preservation?? What can you do on a Wildlife Refuge (it’s a “moderately restricted” land) that you can’t do on a National Wilderness Preservation? Can you do anything on a National Wilderness Preservation? I’m just confused about the differing levels of lands…and these are only federal lands, right?? I know a person who privately owns land can do the whole “easement” thing (what’s the term for that again?), but can private land EVER be made a National Wildlife Refuge or a National Wilderness Preservation if their land was big enough? Could a person ever offer it up like that?? Any help is appreciated…thank you!

So I was on my way home today…and I saw a Toyata Prius Hybrid with a license plate that read, “GASISDEAD.” Now I know this Toyota owner was driving a hybrid so they weren’t using as much gas, say, as my Beetle, but still…they are still using gas driving their Prius. I’m not quite sure what noble point this Toyota owner thought they were making, but I just thought it was interesting to see someone who was trying to spread the message that fossil fuels are nonrenewable and have been/are still being used unsustainably.
So on our most recent test…on question number 3 it said that the statement “The rise in the size of the human population is due primarily to a higher birth rate” was FALSE. Now this might sound extremely stupid, but if more people being born isn’t the primary reason why our population’s growing, then what is?? Also on question four it said that the BEST single measure of quality of life in a country is the infant mortality rate. I put life expectancy, but I know that life expectancy and infant mortality rate are the 2 most useful indicators of overall health in a country. What makes infant mortality rate a better indicator than life expectancy??
Ps–Mr. Willard I hope your surgery went well!!
Okay so after looking over the study guide, I’m a little confused on urban sprawl. It seems like an easy concept though, so I’m not sure if just over complicating it. Does it refer to cities becoming urbanized like New York when they’re growing taller instead of flatter? Is it like a suburb? Also, why does it decrease energy efficiency? To me, it seems it would help increase it because new technology and machinery can be introduced.
Also, how much about the tax incentives and subsidies do we have to know? Just be familiar with it or know details?
The three aspects of sustainability/stability seem kind of sketchy/all the same…the three are inertia/persistence, constancy, and resilience. Resilience and inertia/persistence sound almost exactly alike…it’s number 2 on the study guide of Chapter 6. If anyone could kind of clear these up…it says that inertia/persistence is the “ability of a living system to resist being disturbed or altered” while resilience is “ability of a living system to repair damage after an external disturbance that is not too drastic.” For whatever reason, these are just not making sense to me. If anyone could clear these up that would be great!!
And just a minor question–it says on number 11 of Chapter 4 I wrote down that background extinction is “as local environmental conditions change, species disappear at a low rate.” could anyone provide maybe a time scale for this “low rate”? And maybe give an example? Just sounds a bit vague.
First of all, the atmosphere has 5 layers, but only 4 which with we are concerned. First, there is the trophosphere,which is the one closest to us, and is where weather occurs. Second, there is the stratosphere, the lower part (and the upper part of the trophosphere) in which temperature stabilizes, and about one-third of the way up the stratosphere there is the ozone layer. Third, there is the mesosphere, lastly, the thermosphere. As one goes down in altitude (closer towards us on Earth), the mass increases and so does water vapor. As one goes up in altitude, the amount of ozone increases. Here is a picture I found that is nearly if not completely identical to the one in our handout in class.
Next: Global air circulation is affected by 3 main factors:
1) uneven heating of Earth’s surface by the sun mainly due to the Earth’s tilt on its axis. We demonstrated this in class by letting the “sun” (a heat lamp) shine on the “Earth” (a globe) with 3 thermometers on it: one at the equator, one at approximately the latitude of North Carolina, and one at the North Pole. All 3 thermometers started out at 70 degrees. After a few minutes, we went back and checked them and the one at the equator had become 80 degrees, the one at North Carolina had risen to 78 degrees, and the one at the North Pole remained at 70 degrees. Thus due to Earth’s tilt, the Earth is unevenly heated.
2) Rotation of Earth on its axis. Season is not caused by “distance from the Sun”, but by Earth’s place in rotation. Thus depending on the position of the Earth in its rotation, it will be facing a certain way from the Sun due to its rotation and this will cause change in the season.
3) Properties of air, water, and land.
This leads to “formation” (? Word choice?) of three types of “cells”: hadley cells, ferrel cells, and polar cells. Ferrel cells govern the temperate regions, Hadley cells govern the tropics, and the polar cells govern the poles.
Lastly, the Coriolis Effect. The sun more directly and intensely heats the equator as opposed to the poles, where the sun has to penetrate more atmosphere and the atmosphere in turn deflects or absorbs the sun’s energy. The poles thus have colder air, and the air descends towards the equator. The equator thus has warmer air, which rises towards the poles. Wind can also travel laterally (East and West) in addition to its North and South directions. Due to Earth’s rotation on its axis, wind is given its curved direction, and is named the Coriolis Effect. The way I think of it is when you can go to a carnival and you can go to those stands where you put the paint on a flat surface and then once they start spinning it really fast the paint forms a really cool circular design. The winds are doing their own thing, blowing North and South and East and West, and then when you throw in the Earth’s rotation, and the winds curve.

Help! Okay so I’m a little confused on question 15 on the study guide when it asks for the 3 soil layers in a soil profile. Is the O Horizon not considered one of the 3 layers? Is it just the A, B, and C horizons that are considered THE 3 layers? What is O if it’s not a layer? Any help with this would be lovely! Thanks
This is similar to Kevin’s question…but I am sort of struggling on what to make of the conservationists. Last year in U.S. History we said they were trying to “preserve nature now so it could be exploited later,” but I feel as if maybe that wording is a bit harsh? Would I be correct in saying that Conservationists were making at least an attempt at preserving the environment, which got the ball rolling on the environmental movement? Are they Truaxes? What exactly was their contribution to the Environmental Movement? And also, how did we suddenly go from Industrialism to Romanticism? What made that shift? Those are quite different, from utalitarian to aesthetic/moral..
