Final
Global Climate Change
| Question | Answer |
|---|---|
| 4 points that is discussed in this chapter | ---- |
| 1st | Natural Greenhouse Effect |
| 2nd | Human-enhanced Global Warming |
| 3rd | Physical Effects |
| 4th | Biological Effects of Climate Change |
| Beginning first section | Natural Greenhouse Effect |
| Radiant energy | Waves |
| Short wavelengths | More energy |
| Long wavelengths | Less energy |
| Humans do radiate energy, but... | They can not see it |
| Can organisms sense radiant energy? | YES |
| Species who sense radiant energy | Snakes (Pit Vapor) |
| How can they? | Detect infrared red |
| What can detect ultraviolet? | Bees |
| The electromagnetic spectrum points | --- |
| 1st | If radiation hits the object and the object absorbs it, the temp goes up |
| 2nd | Every object emits radiation |
| 3rd | The wavelength of the emitted radiation depends on the object's temperature |
| The warmer the object | The shorter the wavelength |
| The colder the object | The longer the wavelength |
| Example of heat radiation from an object | Bunsen burner |
| Bunsen burner | We can see the emit radiation and feel the heat |
| The shorts flame is... | The hottest |
| Cooler and hotter objects emit wavelengths... | Outside the visual spectrum |
| Red flame | Longer wavelength |
| Blue flame | Shorter wavelength |
| What does Ultraviolet, X-rays, Gamma Rays cause damage to? | DNA |
| If DNA is damaged what happens | Mutation occurs |
| Which results in... | Skin cancer and severe burns |
| Without an atmosphere | We would have NO life and the earth's temp would be -18 degrees C |
| Our average surface temp is... | 15 degrees C |
| Atmospheric gases can be transparent to one wavelength, but | Absorbs another wavelength |
| The atmosphere is a | Natural global warming |
| An example of Greenhouse Effect | Boiling water on a stove and you turn the dial higher, the temp goes up |
| Pan w/ cover VS. pan w/o cover. Which one take sin more energy instead of loses energy? | Pan w/ cover |
| Earth emits longer or shorter wavelengths? | Longer wavelengths |
| What absorbs wavelengths? | Atmospheric gases |
| Earth is heating up b/c it's absorbing... | Carbon dioxide |
| When gases re-radiate heat downward... | The Earth stays warm and toasty |
| Natural Greenhouse Gases that contribute to Greenhouse Effect | Water vapor / Carbon dioxide / Methane / Tropospheric ozone (O3) / Nitrous oxides / Carbon Monoxide / CFC's |
| What gases contribute to global warming? | Nitrous oxides / Carbon Monoxide |
| Beginning 2nd section | Humans-enhanced global warming |
| Humans are increasing... | All greenhouse gases |
| Since 180 we have increases CO2 by what? | Burning fossil fuels |
| Cycle of forming CO2 | Starts with plant photosyntheziers > They collect solar energy from the sun > form C-C bond > break C-C bonds > burning C combines with O > Creates CO2 |
| Anomalie | See something differ from original average |
| What measurements are used to look at results back in time? | Ice cores |
| Where are Ice cores collected? | Greenland, Antarticia |
| How do we get information from ice cores? | The rings around like a tree |
| Why do ice cores have bubbles? | From trapped air |
| What do they do with the trapped bubbles? | Extract the air and calculate how much CO2 there was |
| Beginning 3rd section | Physical effects |
| Name 5 physical effects | Extreme heat waves / Increases sea levels / Glaciers melting / Artic sea ice shrinking / Earlier springs / Increased fore danger / Change in rainfall patterns / Severe storms |
| What happens when you warm 2 molecules? | They spread apart |
| Which city, state is least at risk near sea level? | Sitka, AK |
| Which city, state is HIGH at risk near sea level? | Galveston, TX |
| Where does thermal expansion come from? | Melting glacier |
| If the water rises to 3 feet what will happen? | East coast cities will become a swamp |
| What East coast cities? | Key West, Baltimore, San Fransico, NY |
| How many people are in the range of sea level rising 3 feet? | 100 million people |
| What is at more risk of sea level than Miami and New Orleans? | Small Islands in the Pacific Ocean |
| Beginning 4th section | Examples of biological effects |
| Examples of biological effects | Polar bears, Mexican jays, and plants in Europe |
| What biological effects have on the polar bears? | Less sea ice, less time for hunting, females weigh 22% less than 20 years ago- Rare to survive |
| What biological effects have on Mexican Jays? | Climate is warming quicker so they are nesting 10 days earlier in South America than in 1971 |
| How many species are in the Northern range? | 520 |
| How many species moved N, stayed, or moved S? | N- 65% / Stable- 34% / S- 2% |
| How many species are in the Southern range? | 40 |
| How many species moved N, stayed, or moved S? | N- 22% / Stable- 72% / S- 5% |
| If the species that were stabled and settled in the South was warm... | They would move North |
| What would happen if the mountains in the Southern range got warm? | Salamander would go extinict |
| What other biological effects might have an effect on species? | Change in crop areas / Distributions of diseases / Health problems caused by pollution |
| What can we do to decrease biological effects? | Conserve energy / Recycle / Use alternative energies (solar) / plant more trees |
| Steady State Phase | Early succession, little nutrient loss |
| Aggradition Phase | Young, vibrant trees begin to grow |
