- Geología Geología Geología.
- Ciencias del clima Ciencias del clima Ciencias del clima
Sus antecedentes:
- La capa residual del polo sur marciano exhibe características dinámicas de la superficie.
- Los modelos anteriores no tenían en cuenta completamente las tasas de erosión observadas.
Objetivo del estudio:
- Para analizar los cambios en la capa residual del polo sur marciano utilizando imágenes de alta resolución.
- Para determinar el mecanismo primario que impulsa la erosión superficial observada.
Principales métodos:
- Adquisición y comparación de imágenes de alta resolución de la superficie marciana de 1999 y 2001.
- Análisis cuantitativo del retroceso de la escarpa y los cambios en la configuración de las características.
Principales resultados:
- Se observaron cambios significativos en hoyos, crestas y montículos.
- Las escarpas retrocedieron de 1 a 3 metros por año marciano.
- Las tasas de erosión son consistentes con la sublimación del hielo de dióxido de carbono, no del hielo de agua.
Conclusiones:
- Las observaciones apoyan la existencia de un gran depósito superficial de dióxido de carbono sólido en Marte.
- El clima marciano no está en equilibrio, lo que indica un cambio climático global en curso.

01:23States of Water
Water exists in any one of the three classical states: solid (ice), liquid (water), and gas (steam or water vapor). The state of water depends on i) the intermolecular forces that draw molecules together and ii) the kinetic energy that leads to movements that pull them apart.
Water freezes when the intermolecular forces are greater than the kinetic energy. Unlike most other substances, water is less dense in its solid state than in its liquid state. This is because each water molecule can form...

01:14The Carbon Cycle
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
02:26Molecular Comparison of Gases, Liquids, and Solids
Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...
02:39Phase Diagrams
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...
01:28Carbon-dioxide Fixation
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...
01:24Microbes and the Carbon Cycle
The carbon cycle is a fundamental Earth process involving the transfer of carbon among the biosphere, lithosphere, atmosphere, and hydrosphere. It plays a critical role in regulating the planet’s climate and supporting life by cycling carbon through various chemical forms and reservoirs. Carbon primarily circulates as carbon dioxide (CO₂), representing its oxidized form, while reduced forms such as methane (CH₄) and organic compounds also play essential roles.Microbial activity is central to...
