Doesn't loose leaves
27
Deciduous temperate
Loses leaves
28
Coniferous
Needle leaf and green all year
29
Mixed forest
A mix between deciduous and coniferous trees
30
Savannas
Tropical, wet and dry seasons
31
Steppe (short grass) praire (long grass)
Rich soil with deep roots, supports great herds
32
Desert (plants)
Xerophytic plants that have small leaves, thick bark, and large roots
33
Tundra
Little plant life with moss and lichens Permafrost prevents deep roots
34
Hydrologic cycle
Movement of water through the hydrosphere
35
Evaporation
Liquid to vapor
36
Condensation
Water vapor to liquid
37
Precipitation
The substance that comes out of the clouds from condensation
38
Headwater
First and smallest streams from run-off
39
Tributary
Small stream that flows into bigger stream
40
Watershed
Area that separates water flowing from different areas
41
Estuary
River meets inlet
42
Water table
The level of all spaces are filled with water
43
Type one
Created by tectonic plates | Ex: mountains, glaciers
44
Type 2
Erosion | Ex: valleys,hills
45
Type 3
Sediment deposited be ice,water,or wind | Ex 3: delta, beaches
46
What are the 8 different energy sources
Coal, petroleum, natural gas, nuclear, hydropower, geothermal, solar, and wind
47
What 4 are non-renewable sources
Coal, petroleum, natural gas, and nuclear
48
What 4 are renewable
Hydropower, geothermal, solar, and wind
49
What is the different between renewable and non-renewable sources
Renewable resources produce energy by themselves and are captured while non-renewable sources are man made bc they need to be burned so we can use them, and they pollute the enviorment
50
Fossil fuels
Dead animals and plants decompose
51
Divergent
Plates move apart, new crust is created. Creates earthquakes and volcanoes. Creates rift valley
52
Convergent
Plates move towards each other, crust destroyed bc one plate goes underneath each other
53
What do convergent plates do
Create steep slope mountains, and earthquakes and volcanoes can result
54
Transform
Plates move against eachother
55
What do transformation plates create
Earthquakes and faults
56
Hotspots
Vertical column of magma in middle of plate
57
What do hotspots create
Because plates move over it then it creates volcano
58
What does weathering do
Breaks rocks
59
Chemical weathering
Water dissolves the rock and disintegrates in
60
Mechanical weathering
Rocks broken apart, water, wind, and glaciers
61
Erosion
Changes surface of Earth
62
Water erosion
Carries sand, dust, soil
63
Wind erosion
Sediment moved
64
Glaciation
Changes landforms by moving glaciers
65
Moraines
Hills created by debris pushed by sheet glaciers
