Environmental Processes

Front 1

Leaf like structure that protects the flower before it opens

Stigma

Front 3

The passage for pollen between ovaries and stigma

Style

Front 4

The organ that protects the ovules of the flower and develops into fruit.

Back 4

Ovary

Front 5

The structure that contains the female gamete and develops into seeds

Back 5

Ovule

Front 6

The male reproductive organ of a flower consisting of anther and filament

Back 6

Stamen

Front 7

Structure that produces pollen

Back 7

Anther

Front 8

Long thin structure that supports an anther

Back 8

Filament

Front 9

Fine dust like granules containing gametes of seed plants

Back 9

Pollen

Front 10

Brightly coloured structure that attracts insects to a flower

Back 10

Petal

Front 11

The female reproductive organ of flower consisting of stigma, style and ovary

Back 11

Carpel

Front 12

Part of plant that is capable of producing the root and shoot systems of new plants. Allows parent plant to a sexually reproduce

Back 12

Rhizome

Front 13

Process where the nitrogen is broken

Back 13

Fixation

Front 14

Transforms ammonia into nitrate

Back 14

Nitrifying bacteria

Front 15

What are the main components of soil

Back 15

Organic material, water, air and rock particles

Front 16

The deposition of solid particles in lower layers of soil from upper layers

Back 16

Illuviation

Front 17

Infertile acidic soil with an ash - like subsurface. Typically under conifer forests.

Back 17

Podsol

Front 18

A sticky water - logged that lacks oxygen

Back 18

Gley

Front 19

Calcareous soils which overlay chalk or limestone

Back 19

Rendzina

Front 20

Well drained brownish subsoils where iron oxidises and bonds to silicate clays

Back 20

Brown earth

Front 21

A group of shallow soils that lack well defined horizons

Back 21

Lithsol

Front 22

An accumulation of partially decomposed organic material in which there is a lack of oxygen. It is formed in Wetlands where flooding obstructs the flow of oxygen from the atmosphere

Back 22

Peat

Front 23

Layers of silt/particles that are pressured into rock by more layers of silt or water

Back 23

Sedimentary

Front 24

Volcanic rock formed from cooled magma

Back 24

Igneous

Front 25

Other types of rock changed in form by heat and/or pressure

Back 25

Metamorphic

Front 26

The process where the surface of the earth is worn down

Back 26

Erosion

Front 27

An erosion process where a material that is being transported were away at a surface (like sandpaper)

Back 27

Abrasion

Front 28

The process of erosion where an object get eroded over time by knocking into other things

Back 28

Attrition

Front 29

An extreme form of leaching where precipitation is higher than evapotranspiration

Back 29

Podsolisation

Front 30

The process of water replacing air in soil. Then microbes use up oxygen and anaerobic respiration occurs. The iron is made soluble and is removed creating the blueish - grey colour

Back 30

Greying

Front 31

The process of top layers of soil becoming more acidic

Back 31

Acidification

Hint 31

Leaching of alkaline ions such as calcium, magnesium and sodium. Plants take these up as well. Processes of taking these plants away such as forestry and agriculture permanently removes these basic ions from the soil.

Front 32

The process of land degradation in dryish areas

Back 32

Desertification

Hint 32

Caused by droughts, over grazing, deforestation, climate change, natural disasters, tillage of soil in agriculture

Front 33

The process of change of species structure in an ecological community over time.

Back 33

Succession

Hint 33

Such as a pond turning into a marsh and then into a woodland

Front 34

Where an area starts to become occupied by life forms such a lichens, mosses and insects. Pioneer species are the first ones

Back 34

Colonisation

Front 35

Harmful chemicals released into the environment cause damage to the environment

Back 35

Pollution

Front 36

Which zone in a water body has photosynthesis occur

Back 36

Epipelagic zone

Front 37

Twilight zone actual name

Back 37

Mesopelagic

Front 38

Midnight zones actual name

Back 38

Bathypelgic

Front 39

High or low pressure for calm weather

Back 39

High

Front 40

Low pressure with air spiralling in

Back 40

Cyclone

Front 41

High pressure with air spiralling outwards

Back 41

Anti - cyclone

Front 42

What are greenhouse gases

Back 42

Water vapour, CO2 methane

Front 43

Warm moist air forced over high areas, the air becomes cooler and condenses. It rains then as it moves down the high area it becomes warmer and dryer

Back 43

Relief rainfall

Front 44

When the land heats it up heats the air above it so it rises and then condenses and causes rainfall

Back 44

Conventional rainfall

Front 45

Where a tropical warm front meets and cold polar front the less dense warm front is forced over the cold front and then condenses and rains

Back 45

Frontal rainfall

Front 46

What's the order of the atmosphere

Back 46

Troposphere

Stratosphere

Mesosphere

Thermosphere

Exosphere

Front 47

Brings windy, rainy/cloudy, stormy weather

Back 47

Low pressure systems

Front 48

Brings clear calm weather

Back 48

High pressure systems
