Wessex and Tumulus Cultures: Bronze Age Britain & Central Europe
Wessex Culture
The Wessex culture flourished in prehistoric Wessex, a region geographically located in the south of Great Britain during the Bronze Age. Chronologically, it developed particularly during the Early Bronze Age. Their burial practices included both inhumation and cremation, with or without burial mounds, either isolated or in groups. Around 1600 to 1400 BC, cremation became the dominant rite.
It is believed that the inhabitants lived in dwellings constructed from reeds and wood. The abundance

Material Properties
Electrical Properties
c1) Electrical Conduction: Allows high levels of energy to be transferred, such as in airlines and power distribution transformers and motors.
c2) Semiconductor: Allows the transmission of electricity, subject to potential difference variables such as temperature. Germanium and silicon are alloyed with nitrogen, phosphorus, and arsenic.
c3) Electrical Insulation: Aims at no power transmission in very high electric fields, e.g., ceramics and polymers.

Landforms Shaped by Water Erosion
On hillsides or slopes, this model is given by wild waters or streams. Wild waters or streams occur on very steep slopes where there is little vegetation. The action of these waters gives modeled as fairy chimneys, gullies, or furrows on the earth.
Floods, in contrast, although there are also just as wild waters when it rains or snowmelt, have a channel that is divided into:
- Catchment area: Usually a lot of small grooves that carry the water.
- Drainage channel: Collects
Urban Heat Islands and Climate Phenomena
Urban Heat Island Effect
The urban heat island effect refers to the difficulty of heat dissipation during nighttime hours in urban areas. While non-urban areas cool down considerably due to a lack of heat buildup, downtown areas with buildings and asphalt radiate heat accumulated during the day. This causes local winds to blow from the outside inward. The phenomenon of temperature rise in densely built urban areas is caused by a combination of factors, including construction, lack of green spaces,

Vicente Blasco Ibáñez (1867-1928)
Valencian Cycle: Focuses on Valencian environments and rural areas (Rice and Tartan, The Cabin, Reeds and Mud).
Political Cycle: Explores republican ideology and anticlericalism (The Cathedral, The Intruder, The Horde).
Final Cycle: Highlights include The Four Horsemen of the Apocalypse, set during World War I and defending the Allies. It has been the subject of countless films.
Naturalism
Naturalism: Emerged in France with the writer Emile Zola (1840-1902). It was

Geothermal vs. Tidal Power: Pros and Cons
Geothermal Energy: A renewable resource from Earth’s interior, used for space heating or electricity generation. It is inexpensive and reliable. Geothermal energy is environmentally benign, emitting fewer air pollutants than fossil fuels. However, it can release hydrogen sulfide gas and cause land sinking. It can also be expensive for heating buildings.
Tidal Power: A clean, renewable resource for electricity generation.
