1
What is permafrost and in what biome is it located?
A layer of nutrient rich soil found in the temperate forest
A layer of frozen soil found in temperate deciduous forest
<p>A layer of frozen soil found in the arctic tundra</p>
A layer of dry soil found in the desert
2
How many types of major deserts and grasslands are there?
4 each
2 each
3 each
6 each
3
Define biome.
<p>An extremely diverse ecosystem</p>
<p>Regions inhabited by certain types of life</p>
An organization technique for organisms
A specific type of desert
4
What is the rain shadow effect?
<p>When air descends & warms and creates arid conditions</p>
When the rain accumulates on the leeward side of a mountain
When the leeward side of a mountain gains moisture
When winds carry moisture to the ocean
5
What is the difference between weather and climate?
<p>Climate and weather are the same.</p>
Weather= general long term conditions, Climate= daily cond.
Climate=general long term conditions, Weather= daily condit.
Weather is temp, Climate is wind currents
6
Which is
not
one of the three major types of forests?
temperate deciduous forest
evergreen coniferous forest
polar chaparral forest
tropical rain forest
7
What roles do mountain ranges serve?
habitat for endemic species, and affects wind circulation
majority of worlds forests, and regulates water cycle
major water storage, regulates climate, hosts biodiversity
Refuge for invasive species, regulates climate, stores water
8
What are the earth's major biomes?
Mountains, plains, plateaus
<p>Tundra,Coniferous&Deciduous forests,desert, grassland</p>
<p>Rainforest, temperate grassland, arctic tundra</p>
Arctic tundra, desert, tropical rainforest, temperate forest
9
What creates air circulation?
rotation of earth and even distribution of heat from the sun
sun's uneven heating and high air pressure
gravitational pull of moon, coriolis effect, convection cell
sun's uneven heating, rotation of earth, convection cells
10
What are the three major types of grasslands?
Savanna, prairie, arctic tundra
Cold grassland, arctic tundra, savanna
Polar ice, plains, tropical rain forest
Temperate grassland, prairie, arctic tundra
11
Which is
not
a human impact on terrestrial ecosystems?
conversion into tree plantations
overgrazing from livestock
damage from off-road vehicles
decreased tourism
12
Why are deserts fragile ecosystems?
fast plant growth, low biodiversity, slow soil regeneration
high biodiversity, slow nutrient cycling, lose heat quickly
slow plant growth, low biodiversity, slow nutrient cycling
lose heat quickly, high soil regeneration, slow plant growth
13
Which is
not
a negative consequence of biome destruction?
increase in greenhouse gases resulting in climate change
low photosynthesis production
low productivity and low ecosystem service output
decrease in biodiversity
14
What are the characteristics of tropical rain forests?
Direct sunlight, high temps, poor soil quality
indirect sunlight, high temps, high soil quality
direct sunlight, low temps, high soil quality
indirect sunlight, low temps, poor soil quality
15
What are the negative impacts of greenhouse gases?
Raises sea levels
Can lead to global warming & increased climate change
Enables seasonal changes in weather
Creates more carbon dioxide and methane
16
What are the benefits of greenhouse gases?
Keeps earth warm, protects from UV rays- blanket for earth
Helps regulate ocean currents
Regulates seasonal and environmental changes
Melting glaciers and increasing sea levels
17
What are Hadley Cells?
high speed currents of wind that occur in upper troposphere
winds between 60 degrees latitude of north and south poles
dry air 30 degrees from equator forms deserts
creates westerlies from 30 to 60 degrees
18
Which is
not
a global wind pattern?
tornados
typhoons
monsoons
el nino
19
Define greenhouse gas.
Gases that contribute to the cooling of the earth
Gases in the earth's troposphere causing greenhouse effect
Toxic gases in the earth's atmosphere
Gases in the stratosphere, causing greenhouse effect
20
What creates ocean currents?
Climate and environmental changes
Prevailing winds blowing over oceans, producing moving water
<p>The sun</p>
<p>Rotating sun and moon cycles</p>
