based on the distribution of earthquake epicenters alone, why is the boundary of the Nazca plate along the east pacific rise, a

divergent boundary rather than a convergent one?

Answer:

The Nazca plate is subducting under the South American plate, and as it sinks the weight of the plate pulls the entire plate away from the east-pacific rise.  Also, convection currents in the mantle/asthenosphere are pulling hotter rock from inside the earth up to the surface at the east-pacific rise pushing the Nazca plate to the east and pushing the Pacific plate west.

A convergent boundry would be on the far east side of the Nazca plate where it is pushing east and the South American plate is pushing west - causing the more dense Nazca plate to subduct under the less dense South American plate.

23: List the different types of radiation according to wavelength? Please put them in the order of longest wavelength to shortes
Butoxors [25]

Explanation:

Radiation means ‘energy that is transported from one spot to another without the need of direct contact between the two locations’, Light in each carries a different amount of energy, this is what we call electromagnetic radiation or electromagnetic waves. Gamma rays are the most energetic, and radio is the least.

<em>In order from longest to shortes wavelenghts we have:</em>

  • Radio waves: they are made by various types of transmitters, given off by stars, sparks, and lightning, they have the lowest frequencies (longest wavelenghts) in the electromagnetic spectrum and are used mainly for communications.
  • Microwaves: they are extremely high-frequency radio waves (Their wavelength is usually a couple of centimeters) made by various types of transmitters.
  • Infra-red waves: they are just below visible red light in the electromagnetic spectrum, they're given off by hot objects.
  • Visible lights is the tiny part of the electromagnetic spectrum our eyes can detect.
  • Ultra-Violet: this light is given off by the Sun in large quantities. We call it "UV" for short and can also be used to kill microbes.
  • X-rays: they are very high-frequency waves that carry a lot of energy. They will pass through most substances, and this makes them useful in medicine and industry to see inside things.
  • Gamma rays: they are given off by stars and by some radioactive substances. They are extremely high-frequency waves (the shortest wavelength) and carry a large amount of energy. They pass through most materials.

In the image, I annexed you can see the electromagnetic spectrum with the type of radiations from the shortest to the longest wavelengths.

I hope you find this information useful and interesting! Good luck!

In the short term, a rainstorm might damage buildings and habitats by causing a river to flood. What positive effect might a rai
ss7ja [257]
Rainstorms provide natural moisture to the environment. Receiving rain will keep plant life healthy, give animals a natural reservoir to drink from, as well as keeping the life in the river healthy. Though a flash flood may cause damage to buildings and habitats at first, buildings can be fixed and over time, wild flora and fauna will return to the area, often more plentiful, is there is a good amount of moisture <span />

What are HDI’s shortfalls
Zarrin [17]

Answer:HDI reflects long-term changes (e.g. life expectancy) and may not respond to recent short-term changes. Higher national wealth does not indicate welfare. ... However, HDI can highlight countries with similar GNI per capita but different levels of economic development.

Describe the mode of formation of metamorphic rocks​
djverab [1.8K]
Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet. In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock. Sedimentary rocks were originally sediments, which were compacted under high pressure. Hope this helps!
