Central Chile’s Diverse Ecosystems: Forests, Scrub & Climate
Central Chile’s Diverse Ecosystems
Sclerophyllous Forest and Scrub
Region of Central Chile: Mountain region from the 31st parallel south (LS) Biobio to the Imperial rivers. Features Andean summits. The maritime basin prevents penetration and acts as a rain shadow, especially south of Nahuelbuta.
Key Difference: Broad-leaved evergreen sclerophyllous forest and broad-leaved evergreen sclerophyllous scrub. Broad-leaved evergreen sclerophyllous forest (sclerophyll: hard and tough leaf that reduces water

Earth’s Structure and Composition
The Earth is a sphere, slightly oblate at the poles, and divided into three main zones.
The Mantle
The mantle is composed of various materials, some of which are partially melted and known as magma.
The Nucleus
The nucleus is divided into two layers: an inner core, which is solid, and an outer core, containing molten material.
The Crust
The crust varies significantly in thickness. In some areas, it is very thick, forming the continents. In other areas, it is much thinner,

Human Evolution and Environmental Impact
Our species, Homo sapiens, has evolved through the development of mind and culture, creating the science and technology needed to adapt nature to our needs. Thanks to tools and machines, we have acquired a tremendous capacity to transform nature, far exceeding the scale of biological evolution. Humans have replaced biological evolution with culture.

Red River, Slope, and Atlantic Basins
A river is a set of surface water courses, streams, and rivers channeled that pour their waters into a river, lake, or sea.
Orinoco Basin
The Orinoco basin has a length of 880,000 km² and 640,000 km² are within our territory. The Orinoco River is 2150 km long, extending from the thin bill Chalbaud to the Atlantic. The river in its upper course presents a series of rapids (Atures and Maypures being the largest). In its course, there are 574 islands (the largest

The properties of a metal depend on the size and arrangement of its grains (granular structure). This structure is very important.
Types of HSS Steel
Microalloyed steel, dual phase steels, rephosphorized steels, bake hardening steels, IF steels, TRIP steels.
Active Materials
The most remarkable property of active materials lies in their response to specific stimuli. These materials have varying properties and change automatically.
Physical Properties
- Fusibility: The property of metals to liquefy under
