Interior of the earth
This document provides information about the layers of Earth's interior. It is divided into three main layers: the crust, mantle, and core.
The crust is the outermost layer and is divided into two sublayers - the continental crust (Sima) and oceanic crust (Sial). Sima is less dense and older, while Sial is denser and younger. The mantle, the second layer, is also divided into upper and lower sections. The upper mantle is solid while the lower mantle is molten. The core is the innermost layer and consists of nickel and iron. It has a solid inner core and molten outer core. Temperature and pressure increase significantly with depth into Earth.
Inside the earth
The interior of the Earth is layered in spherical shells like an onion, with each layer defined by its chemical or rheological properties. The crust is the outermost layer, made of oceanic or thicker continental crust. Below is the highly viscous mantle, composed of iron- and magnesium-rich silicate rocks. Within the mantle is the asthenosphere, which flows and moves the tectonic plates atop it. The liquid outer core surrounds a solid inner core, with both cores being the densest parts of the planet. Convection currents in the mantle powered by heat transfer drive the movement of tectonic plates.
Oil pollution
Oil pollution poses serious threats to the environment. When oil is spilled into oceans and waterways, it can severely damage ecosystems and harm wildlife. Effective cleanup and prevention methods are needed to protect sensitive habitats and reduce negative impacts of oil pollution on the natural world.
The ozone hole
The document lists two names, Silvia Román and Paula Sánchez. It does not provide any other details about these individuals, such as their occupations, roles, or relationship to each other. In just mentioning these two names, the document gives very limited information that does not provide much context or insight.

Deforestation by Saul Mayordomo, Adrian george perez and Jose miguel perez hita Antonio Saorín Pérez-muelas
The document discusses the issue of deforestation. It notes that around 11,000 years ago, 60% of the Earth was covered in forests but now only about 1/5 of land has forests. Deforestation occurs for various reasons like using trees for fuel, clearing land for agriculture, and development. This removal of trees without replanting has led to damage of habitats, loss of biodiversity, increased carbon dioxide in the atmosphere, soil erosion, and degraded wastelands. Reforestation efforts are needed to counter the effects of deforestation.Deforestation
The document summarizes the causes and effects of deforestation. It notes that around 11,000 years ago, 60% of the Earth was covered in forests but now only 1/5 remains due to clearing for various uses. Deforestation results in damage to habitats and biodiversity loss. It disrupts the water cycle and causes issues like soil erosion, flooding, and drought. Large amounts of carbon dioxide are also released into the atmosphere from burned or rotting trees. Reforestation efforts are needed to mitigate the effects of deforestation.

ACERO Y ACERO INOXIDABLE, Natalia M. Carmen G.
The document discusses steel and stainless steel. It defines steel as an alloy of iron with carbon as the primary alloying element. Steel was first produced around 4,000 years ago and is strong, resistant to corrosion, and 100% recyclable. Stainless steel is an alloy of iron, chromium, and nickel that does not rust or stain easily. It was discovered in 1913 and is used widely in cookware, buildings, transportation and industrial equipment due to its corrosion resistance, strength and recyclability. Both steel and stainless steel can be recycled repeatedly without loss of quality, saving resources and reducing environmental impact with each recycling.

It is a semiconductor used in electronic chips, solar cells, and other technologies due to its strength, thermal conductivity, and elasticity. Graphene is an allotrope of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It was discovered in 2004 by Andre Geim and Konstantin Novoselov, who won the Nobel Prize. Graphene has unique properties including high strength, thermal and electrical conductivity, and transparency. Potential uses include shielding, electronics, vehicles, and information technologies.
Ardi
Ardipithecus is a genus of early hominid found in Ethiopia that lived approximately 4.4 million years ago. It is considered a descendant of Orrorin tugenensis and a direct ancestor of australopithecines. There were two species, A. ramidus and A. kadabba. A. ramidus had a skull similar in size to great apes and evidence shows it moved in a bipedal manner. New evidence from the Aramis site in Ethiopia, where a partial skeleton of A. ramidus was found, indicates through sedimentological and isotopic analysis that it lived in a river-margin forest within a savanna landscape, in
Coronary heart disease
Coronary heart disease is caused by plaque buildup in the coronary arteries that supply blood to the heart. Over many years, plaque narrows the arteries and reduces blood flow. If plaque ruptures, a blood clot can block blood flow and cause a heart attack. A heart attack occurs when an area of the heart muscle dies from lack of oxygen-rich blood. Angina is chest pain that occurs when blood flow to the heart is reduced. Coronary heart disease is the leading cause of death in the United States and lifestyle changes, medicines, and procedures can help prevent and treat it.
Gripe A y Gripe Española
La gripe española de 1918 fue una pandemia mortal que mató entre 50-100 millones de personas, mientras que la gripe A de 2009 causó síntomas graves similares a la gripe común pero más severos. Ambas enfermedades se transmiten por vía aérea a través de gotitas al toser o estornudar, y su prevención requiere evitar lugares concurridos y el contacto con personas enfermas.
Dengue silvia
Dengue fever is an infectious tropical disease caused by the dengue virus and transmitted by Aedes mosquitoes. Symptoms include fever, headache, and joint pains, and in rare cases it can develop into dengue hemorrhagic fever resulting in bleeding and organ failure. The dengue virus infects 50 to 390 million people worldwide annually, leading to thousands of deaths, especially in Southeast Asia.
