Geography II
| Definition | Term |
|---|---|
| a shape on the plant's surface, such as a mountain, valley, plain, island or peninsula | landform |
| land that rises higher that 2,000 ft | mountain |
| an example of a landform; rises less than 2,000 feet | hill |
| a hill with a flat top | plateau |
| stretches of mostly flat land | plain |
| 250 million years ago, all of Earth's continents were connected forming on giant landmass | pangaea |
| a theory suggesting that Earth's surface is divided into a dozen or so slow-moving plates, or pieces of Earth's crust | plate tectonics |
| covers all of Earth's surface, and helps complete the theory of plate tectonics | plate |
| the process by which rock is broken down into smaller pieces | weathering |
| the movement of sediment from 1 location to another | erosion |
| the gaseous envelope surrounding the earth and the air | atmosphere |
| what physical process occurs within the Earth? | landforms begin to start forming (and geothermal activity) |
| movement of water from Earth's surface to the atmosphere and back | water cycle |
| any material in nature that people use and value (water, food, vegetation) | natural resource |
| natural resource that r used of other things like a tree | raw material |
| something that can be re-used or made into something else (water cycle) | recyclable resource |
| resources Earth replaces naturally | renewable resource |
| resources that cannot be replaced | nonrenewable resource |
| nonrenewable resources that formed from the remains of ancient plants and animals | fossil fuels |
| why is energy a scarce natural resource? | because it is produced by nonrenewable resources and it will eventually run-out |
| the short-term changes in the air of a given place and time | weather |
| the degree or intensity of heat present in a substance or object; shown by a thermometer | temperature |
| water that falls to Earth's surface as rain, snow, sleet, or hail | precipitation |
| a region's average weather conditions over a long period | climate |
| plants considered collectively, especially those found in a particular area or habitat | vegetation |
| what role does wind and water play in creating our climate? | wind and water move heat around Earth, affecting how warm or wet a place is wind- move moisture around the Earth water- it gives us precipitation for crops and water to drink |
| what is the difference between weather and climate? | climate is a region's weather over a long period, when weather is just short-term changes in the air for a given place or time |
| what r the 5 major climate regions and what kinds of vegetation grow in each... | 1. tropical- rain forests,grasses 2. dry- hardy plants (cacti) trees and shrubs by water 3. temperate- scrub woodland, grass, evergreen forests 4. polar- northern evergreen forest, moss, lichens, low shrubs 5.highland- ranges form forest to tundra |
| what physical processes occur on the Earth's surface? | weathering, erosion (landforms r shaped) |
