Understanding Pressure and Atmospheric Phenomena
Concepts
Pressure: Force acting on a unit area. The SI unit of pressure is the Newton per square meter (N/m²), which is called the Pascal (Pa).
Pascal: Pressure exerted by a force of one Newton on a surface area of one square meter.
Hydrostatic Pressure: Pressure originating inside a liquid under its own weight.
Hydraulic Press: A mechanism consisting of two cylinders of different sections, connected by a tube containing a liquid that reaches the same height in both. These cylinders are closed by different-

What is Geothermal Energy?
- Geothermal energy is the Earth’s internal heat.
- It produces phenomena such as:
- Movement of the continents
- Volcanoes
- Earthquakes
- The origin of mountain ranges and ridges
- The formation of some rocks and their deformation
Where Does the Heat Inside the Earth Come From?
- The impact of various stellar bodies colliding with the planet during its formation.
- Radiation emitted by the decay of different radioactive elements present on Earth, such as Uranium, Thorium, and Potassium.

Layout of Gravity Sewer Systems
The systematic arrangement of gravity sewers must be performed to drain wastewater (WW) and concentrate it at the lowest point, the wastewater treatment plant (WWTP). The following must be taken into account:
- Terrain configuration
- Type of built-up area
- Recipient disposition
- Other eventual conditions
Generally, sewers are designed to drain wastewater into the WWTP in the most optimal way.
- Radial System: Tends to be applied for the drainage of closed hollow basins without
Understanding Erosion, Transportation, and Sedimentation
Erosion, Transportation, and Sedimentation
1. Definitions:
- Erosion: The process of dislodging and moving material resulting from the weathering of rocks by wind, water, waves, and ice.
- Transportation: The movement of eroded materials to other locations.
- Sedimentation: The deposition of transported materials by agents of erosion.
2. How are Water Gullies Formed?
Water gullies form with rain or snowmelt that infiltrates into the ground, leading to runoff and the formation of gullies and fairy chimneys.

Current Panorama of Spanish Agriculture:
Factors Influencing Farming: Farming is determined by a combination of physical and socioeconomic factors. Physical factors include soil and climate, while socioeconomic factors encompass the active population and land ownership structure.
Physical Factors
Extension of Agricultural Land: Of Spain’s 50.5 million hectares, a breakdown for agricultural purposes includes unproductive land, untilled land, and the Utilized Agricultural Area (UAA). The UAA constitutes

Human Impact on the Environment
Humans use the natural environment as a resource. Several factors contribute to our impact:
- Population Size: As populations grow, they require more resources, including land for food production, housing space, raw materials for industry, and transportation infrastructure.
- Technology: Current technology enables humans to alter vast areas of land.
- Energy: Increased energy use leads to more significant environmental changes.
- Consumption Patterns: The continuous production
