Answers

Answer:

Pangea es el supercontinente que existió hace 250 a 210 millones de años, desde que se originaron todos los continentes actuales. Pangea estaba rodeada por un océano, Panthalassa. Pangea era una gran masa de tierra que finalmente se rompió por la tectónica de placas.

Durante el Jurásico, Pangea comenzó a desintegrarse. Primero, se formó una brecha de tres brazos entre lo que se convertiría en los continentes de África, América del Sur y América del Norte. La actividad volcánica creó una cuenca que luego se convertiría en el Océano Atlántico. Pangea se dividió primero en dos paleocontinentes, Laurasia y Gondwana (América del Sur siguió siendo parte de Gondwana durante algún tiempo). Después de eso, ambos paleocontinentes se dividieron aún más en los continentes de hoy.

Can hydrogen Bonds form among hydrogen chloride molecules? Why?​

Answers

Explanation:

Despite its electronegativity, size of a chlorine atom is larger and hence, the electron density is low. So, HCl does not have hydrogen bonding but, HF,NH3,H2O shows hydrogen bonding.The hydrogen bond does not form because the chlorine atom is too large. Despite chlorine's high electronegativity its big size lowers the negative charge density and it is not enough to attract a hydrogen atom in a stable phase. Nevertheless, there is a small dipole-dipole attraction between adjacent HCL molecules.

Leé el siguiente texto y responde: Por necesidad, por interés o por ignorancia, los diferentes grupos sociales vamos lentamente degradando el ambiente que nos rodea, incrementando nuestras vulnerabilidades o potenciando amenazas, sean de origen antrópico o natural. Las acciones que realizamos sobre nuestro medio, el uso o el desecho que hacemos de los recursos naturales están guiados por el interés inmediatista de responder a nuestra necesidades, pero este manejo genera efectos que se van acumulando, hasta que viene la sorpresa, el desastre "natural" que nadie esperaba, pero todos construimos día a día, año a año. a)¿Por qué creen que se menciona "natural" entre comillas?

Answers

Answer:

Natural se encuentra entre comillas porque en realidad el desastre no es provocado por la naturaleza, es decir, que no es natural sino que es una consecuencia del mal uso de los recursos naturales, de la degradación del ambiente para satisfacer necesidades inmediatas en donde no se toma en cuenta el daño que estamos generando. Este daño se acumula e incrementa nuestras vulnerabilidades o potencia las amenazas, por ende los desastres no son naturales sino que son causados por el hombre.

Explanation:

Podemos deducir que la palabra natural se encuentra entre comillas al leer "vamos lentamente degradando el ambiente que nos rodea, incrementando nuestras vulnerabilidades o potenciando amenazas..." o "Las acciones que realizamos sobre nuestro medio, el uso o el desecho que hacemos de los recursos naturales...este manejo genera efectos que se van acumulando." En estas líneas se evidencia que los desastres naturales en realidad no son causados por la naturaleza sino que son una consecuencia del hombre por utilizar mal los recursos naturales y no cuidar el ambiente.

Why are sedimentary rocks only found on or close to Earth's surface?

Answers

Answer:

Erosion breaks existing rocks and turns them into sediments. The sediments can be formed into rocks by the chemical reactions of dissolved seashells ( Calcium Carbonate.) This reaction can form sediments into rocks very quickly like the formation of concrete ( same chemical reaction). Erosion only happens on the earth's surface.  

As erosion only happens on the earth's surface, sedimentary rocks are only formed on the earth's surface.

In other words:

Sedimentary rocks only found on or close to Earth's surface because sedimentary rocks are made of materials deposited in layers at the Earth's surface.

Answers

Answer:

The zone of convergence between sub-tropical and polar air masses, and where frequent traveling storms take place, is along the sub-polar latitudes.

Explanation:

Convergence zones are meteorological systems that have a strong impact on global climate quality. These systems are formed by the interaction of various meteorological events that occur between different latitudes.

The convergence zone, which encompasses the subtropical and polar air masses, has an influence on the amount of storms that occur frequently. This convergence zone is located along subpolar latitudes, being strongly influenced by the humidity found in this region.
