External Geodynamic Processes: Landslide and Flood Risks
Landslide Risks from External Geodynamic Processes
Flood Risk: Causes of Natural Inundations
Causes of Climatic Origin
- Coastal cyclones
- Extreme weather events
- Rapid ice and snow melt
- Temperate climates with marked periods of drought followed by torrential rainfall
Obstruction of Natural River Channels
- Direct anthropogenic causes: Construction in riverbeds, dam breaks, waterworks, sudden water release, mining and tailings
- Indirect anthropogenic causes: Deforestation, loss of vegetation cover, poor farming
Environmental Pollution: A Threat to Human Existence
Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurities to the environment. The environment consists of Earth, water, air, plants, and animals. If we pollute them, then the existence of humans and nature will be hampered.
The Escalating Problem of Deforestation and Global Warming
It is true that trees are being cut down rapidly. Our Earth is becoming warmer. If pollution continues, the day is not far when our Earth will be a boiling pan and

Question 2: Environmental Impact Assessment of Algarrobico Beach
Location: Algarrobico Beach, Cabo de Gata Natural Park (Almería)
a) Description of Environmental Impact
The image depicts the bottom of the blade at Algarrobico Beach, located within the Cabo de Gata Natural Park in Almería. The photograph reveals a significant environmental impact, primarily a visual and landscape impact, which is negative and partly reversible. This impact stems from a change in land use, transitioning from a protected

Aljaferia Palace: Architectural Features
The top of the arch has no scrolls but features lobed arches. The arches at the bottom allow access to the Throne Room. We see mixtilinear arches, a novelty of the Taifa kingdoms, originating from Tunisia. There is a prolongation of the branches from the arches. A horseshoe arch at the top is supported by paired columns. Medallions are placed at the corners of the arch panels around the arcade.
Throne Room Characteristics
The Throne Room loses depth, reflecting

Mineral Resources and Their Extraction
Industrial Resources
Ornamental Rocks: Examples include marble and granite. Quarries extract these in block form, requiring minimal treatment before use.
Sand & Gravel: These are fragments of rock, gravel, and sand. Extracted from gravel pits, they are washed and crushed for use in concrete and fill.
Rocks with Industrial Processes: Limestone, dolomite, and some clays are used to make cement. Sandstones rich in quartz and quartzite are used to make glass.

The Origin of the Universe
The Sun is a yellow star located on the outskirts of the Milky Way galaxy. Galaxies are clusters of billions of stars held together by the force of gravity. Before the appearance of the universe, it was empty of matter.
The Big Bang
The Big Bang is a theory that explains how the universe was formed. According to this theory, the universe was formed due to a great expansion of elementary particles. At the beginning, positively charged particles collided in a sea of photons.
