the interior composition and structure of earth have been deducted in part from: a) analyses of the behaviour of seismic waves b) chemical studies of meteorites c) the density of iron, granite and basalt d) all of the above.

Answers

Answer 1

Answer: A. Analyses of the behavior of seismic waves.

Explanation: "The layering of Earth has been inferred indirectly using the time of travel of refracted and reflected seismic waves created by earthquakes" (Structure of the Earth). Combining the layered structure and reflection magnitudes with the magnitude of gravity (and therefore the average density of the Earth), we can get a pretty good idea of the density of each layer. By integrating density, we can calculate the pressures at depth."

Que Piensas de los puertorriqueños que viven en los estados Unidos?​

Answers

Answer:

Personalmente, pienso que los puertorriqueños que viven en los Estados Unidos no deben ser considerados como extranjeros, pues no son tales. Ello debido a que, desde 1917, el gobierno federal reconoce a toda persona nacida en el archipiélago como ciudadano americano.  

Por lo tanto, debe considerarse a los habitantes de los Estados Unidos nacidos en Puerto Rico como ciudadanos americanos con la misma cantidad y calidad de derechos que todo otro ciudadano americano.

how can poor infrastructure be a cause of drought pls explain in not a sophisticated way :)

Answers

Answer: Infrastructure can be responsible for drought.

Explanation:

Drought is a natural disaster in which the area receives a very low amount of annual rainfall. This causes the scarcity of water on the land. The natural and artificial reservoirs of water get dried up in drought as water does not accumulate and replenish in this reservoir because of lack of adequate rainfall. Infrastructure can cause drought if there is no sufficient artificial reservoir which can help in irrigation of field, use for household works, and for other purposes which can help in scarcity of water. Infrastructure which reduces the forest cover also affects the water cycle causing drought in neighboring regions.

Based on observations he made with his naked eye, Ptolemy saw the Universe as a set of nested, transparent spheres, with Earth in the center. He posited that the Moon, Mercury, Venus, and the Sun all revolved around Earth.Nicolaus Copernicus was an astronomer who proposed a heliocentric system, that the planets orbit around the Sun; that Earth is a planet which, besides orbiting the Sun annually, also turns once daily on its own axis; and that very slow changes in the direction of this axis account for the precession of the equinoxes.Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science". ... He invented the thermoscope and various military compasses, and used the telescope for scientific observations of celestial objects.(1) agricultural improvements that made possible the provision of food for a larger nonagricultural population, (2) economic changes that resulted in a wider distribution of wealth, the decline of land as a source of wealth in the face of rising industrial production, and increased international trade, (3) political changes reflecting the shift in economic power, as well as new state policies corresponding to the needs of an industrialized society.These are the first three industrial revolutions that transformed our modern society. With each of these three advancements—the steam engine, the age of science and mass production, and the rise of digital technology—the world around us fundamentally changed.

Answer:

Runoff

Explanation:

The stage of water cycle where water moves downward from the force of gravity is runoff.

It comes after the precipitation stage when the water has fallen in a form of rain and seep through the soil, due to the force of gravity this water moves down the hills and mountains through a process called runoff.  

Under the force of gravity, water follows along the steep hills and then join into stream and rivers. Later on these streams and rivers will move down to join lakes and oceans.
