101 Fascinating Earth Facts: From Volcanoes to Earthquakes & Beyond
1. What is the hottest place on Earth?
While you might think it’s Death Valley in California, you’d be slightly off. Many days it is indeed incredibly hot there, but on September 13, 1922, El Azizia, Libya recorded a scorching temperature of 136 degrees Fahrenheit (57.8 degrees Celsius). This surpasses the highest ever temperature measured in Death Valley, which was 134 degrees F (56.6 º C), recorded on July 10, 1913.
2. And what is the coldest place on Earth?
The coldest temperature ever measured

what determines where a species live & migrate?
strong effects :
- the climate (temperature, precipitation) → terrestrial organisms
- light & nutrient availability → aquatic organism
dispersal (too crowded can cause limited resources) & interactions (prey-predator) among organisms also affect where species live
what is ecology?
ecology = scientific study of the interactions between organisms and the living and nonliving components of their environment (temperature, sunlight, etc) → a science
A Journey Through Earth’s Dynamic History
The Atmosphere: A Dynamic Force
Water vapor, carbon dioxide, and methane are greenhouse gases that play a crucial role in regulating Earth’s temperature. These gases trap heat emitted by the Earth, raising the planet’s surface temperature to a habitable level. Without them, the average temperature would plummet to a frigid -18°C.
The atmosphere is constantly in motion. When air near the Earth’s surface absorbs heat, it expands, becomes less dense, and rises. Cooler air masses then move in to replace

Folds, Faults, and Block Failed
Folds
Originated in structures, which must be on the surface a sequence of sedimentary rocks.
When you begin to destroy, a series of cracks will develop which are going to be called Valley anticline.
More Advanced Stage of Erosion
From the formation of high reliefs, lithology can be assigned, which is the rock type that corresponds to the high and low reliefs.
Inversion of Relief or Topography
What once was down is now up, originating mountains hung synclines.

Biogeochemical Cycles
A biogeochemical cycle is a set of processes that a chemical element undergoes as it moves between different subsystems and molecules.
Hydrological Cycle
: a biogeochemical cycle is also q runs through the four subsystems involved in many changes in the elements, ie x in the hydration of non-metal oxides in the atmosphere causing aerosols in the hydrolysis of minerals in the earth’s crust producing weathering of rocks. In CILC of water is also an effective q conveyor moves the
