earth science : the biosphere.

biosphere

part of earth where life exists.

biosphere

is the portion of the Earth that is inhabited by life. this includes both living and non living parts.

biota

collection of just living things in biosphere

biosphere, hydrosphere, atmosphere, geosphere or lithosphere

name all the major systems of earth.

hydrosphere

all of Earth’s water, ice, water vapor

atmosphere

the air blanketing Earth’s solid and liquid surface

geosphere

features of Earth’s surface (continents, rocks, sea floor, and everything below Earth’s surface

gaia hypothesis

this hypothesis says that earth itself is kind of a living organism.

climate

this is the prevailing weather of a region.

weather

this is the day to day condition.

climate

this is the long term pattern of weather conditions.

coastal areas

these landmasses have the tendency o have smaller changes in temperature (moderated by oceans)

mountains

these landmasses have large effect on climate that causes precipitation

tropical rain forest, grassland, desert, temperate forest, taiga and tundra.

can you name all the 6 biomes of earth?

tropical rainforest biome

this biome has warm temperatures, abundant precipitation all year, lush forests

Grassland Biome

in this biome, primary plant life is grass. Occurs in variety of climates

desert biome

in this biome, it is an arid environment, little precipitation, four types: hot, semi-arid, coastal, and cold

temperate forests

this biome include deciduous forests and rainforests. Temperate deciduous forests have hot summers and cold winters. Deciduous trees are the dominant plant species

taiga

this biome is found in cool northern climates. Long winters, short summers. Small amount of precipitation

tundra

in this biome, they have far northern latitudes with long winters (10 months) limited precipitation, permafrost

chaparral

can you name me one minor biome?

chaparral biome

this is a minor biome that has hot, dry summers and cool, moist winters

true

Polar ice caps and mountains are not considered biomes

polar ice caps

they have no soil and do not have specific plant community. usually found at south and north pole, and most animals in here depend on sea for food.

photic zone

what zone in the ocean zone receives light?

aphotic zone

what zone in the ocean zone does not receives light?

estuaries

are dynamic environments where rivers flow into the ocean

estuaries

they are partially enclosed body of water formed where a river flows into the ocean. they have a mix of fresh and salt water.

fresh water ecosystem

examples of these are rivers, streams, wetlands

fresh water ecosystem

this is one of the most productive ecosystems on Earth
