L2: Life on Land Flashcards
The study of how organisms in a particular area are influenced by factors such as climate, soils, predators, competitors, and evolutionary history
Natural History
An approach that seeks to preserve tropical dry forests for its own sake and as a place that provides a host of human benefits, ranging from drinking water to intellectual stimulation
Biocultural Restoration
Areas distinguished primarily by their predominant plants and are associated with particular climates
Biomes
What causes climatic variations across the globe?
- Uneven heating of Earth’s surface
- Spherical shape of the Earth
- 23.5 degrees tilt
- Precipitation
During this time, the northern hemisphere is tilted towards the sun and receives more solar energy
Northern Summer
During this time, the sun is directly overhead the tropic of Cancer
Northern Summer Solstice
(June 21)
During this time, the sun is directly overhead the tropic of Capricorn
Northern Winter Solstice
(December 21)
During this time, the northern hemisphere is tilted away from the sun and receives less solar energy
Northern Winter
During these times, the sun is directly overhead the equator and both hemispheres receive equal amounts of solar energy
Spring Equinox
(March 21)
Autumnal Equinox
(September 22 or 23)
These are winds that blow from the northeast in the NH and from the southeast in the SH
Northeast and Southeast Trades
These are winds within the temperate belt (30-60 latitude) blowing mainly from the west
Westerlies
These are winds predominant at high latitudes moving from the east
Polar Easterlies
What is the Coriolis Effect?
- The reason why prevailing winds do not move in a straight north-south direction
- Causes winds to deflect to the right (NH) and to the left (SH)
One of the most significant aspects of soil structure, observed by digging a soil pit
Vertical Layering
Soil layer that lies at the top of the profile
