Environmental Impacts of Human Activities on Earth
Environmental Impacts of Human Activities
A significant change in the environment caused by human activity is called an environmental impact.
Types of Impacts
According to the Conclusions
- Positive effect: Improves the environment or human nature itself.
- Adverse impacts: Harm human nature itself or the environment.
What Affects the Environment
- Environmental Impacts: Changes to some other living beings, bodies of water, air, and land relief.
- Human impacts on the environment: Directly affect our way of life.
Environmental Issues: Biodiversity, Ozone, and Sustainability
Biodiversity
Biodiversity is the full variety of life on Earth, encompassing every plant and animal species. It also includes the variety of ecosystems and the differences in genetic diversity within species.
Ozone Layer
The ozone layer is the area of the stratosphere that contains a relatively high concentration of ozone. The reduction in its thickness is due to the chlorine contained in Chlorofluorocarbons (CFCs) used in aerosols and refrigerants. This problem affects plant, animal, and human life.

Chile’s Far North: Regions and Towns
This section covers the following regions: Region I (Tarapacá), Region II (Antofagasta), and Region XV (Arica and Parinacota). Geographically, it extends from the northern limit line (Concord), approximately at the 18.5th parallel, to the Copiapó River, approximately at the 26.5th parallel (ecotones).
Characteristics of the Far North
- Characterized by absolute desert, devoid of vegetation except for some isolated areas.
- Plains over a thousand feet high.
- Warm, even
Rock Deformation, Plate Tectonics, and Earth’s Dynamics
Rock Deformation and Its Types
Deformation is the change in position, shape, or volume experienced by rocks under stress.
Types of Deformation:
- Elastic: The material deforms under stress but returns to its original shape when the stress is removed.
- Plastic: The material deforms under stress and does not return to its original shape when the stress is removed.
- Fracture: The material loses internal cohesion and breaks under stress.
Elements of a Fold:
- Axial Plane: Divides the fold into two symmetrical halves.
Understanding Topography, Geophysics, and Related Fields
Understanding Topography and Its Applications
Topography is the study of the methods needed to represent an area in full detail, whether natural or created by human hands. It also involves the knowledge and handling of instruments needed for this purpose.
Topometry
Topometry is the set of methods and operations related to the measurement of angles, distances, and gradients for locating the position of a point in space relative to some reference system.

Oceanic Climate, Rivers, and Vegetation
(Galicia, Asturias, Cantabria, Basque Country, Navarra, Aran Valley)
Rainfall is abundant year-round. Cloudiness and humidity are high, and temperatures are mild. Because of this climate, there are many rivers that are abundant, very regular, short, and have considerable unevenness with great erosive force. The abundance and strength of the water from these rivers allow for significant energy recovery. Temperate deciduous forests thrive in areas of oceanic climate.
