Environmental concerns are important, but which country has offers the least amount of help to its environment?
China
South Korea
North Korea
Japan
Answer:
North Korea
Explanation:
All of the listed countries are causing damage to the environment, but Japan, South Korea, and China are also trying to fix the problem, while North Korea don't seem to be bothered about it. South and Japan in particular are investing a lot in renewable energy sources in order to decrease the emission of greenhouse gases, as well as having strict laws about protecting the environment. China is one of the biggest polluters in the world, but at the same time is putting lot of efforts lately to improve the well being of the environment, having big success in making the deserts in the north of the country covered with greenery. North Korea is another case. It is a country that in order to be able to sustain itself uses everything that it can, usually meaning that the environment is heavily damaged, and in order to not lose any of the very important finances for their existence, they don't spend anything to protect the environment.

Explanation:
When a galaxy is observed moving toward the earth, what visible radiation (as in, which color) will it emit?
Answer:
When a galaxy moves towards the earth, it will emit blue colour light.
Doppler blueshift occurs when the source of light is coming near to its observer. Alternatively, Doppler redshift occurs when the emitter of light moves away from its observer.
Blueshift occurs when wavelength of light decreases. Redshift occurs when wavelength of light increases.
Blueshift makes the colour of the light move from red towards blue.
The shift in wavelength is determined by observing the spectrum with a spectrometer.

Metallic minerals become concentrated in liquid magma because they __________.
Answer:
Metallic minerals become concentrated in liquid magma because they undergo igneous and hydrothermal processes.
Explanation:
The magma that is formed deep beneath the 'surface of the Earth' carries various earth minerals to the surface of the Earth through convective actions. It is responsible for the melting of solid minerals in the interiors of Earth. The minerals as a result of melting, liquify and reach the levels where their density allows them to float. This results in the concentration of minerals in liquid magma.Lakes and rivers account for slightly more available freshwater than groundwater does.

The characteristics of the monsoon weather are the periodical change of draft, the humid summertime and the dry wintertime. In a world-wide judgment, there are various ranges which have a monsoon weather.
If enough water pressure builds under the surface of the ground, the water can burst through cracks in the surface, forming a(n) _______.
Answer:
Geyser
Explanation:
A geyser is a type of spring that is characterized by the discharge of the water and is rushed out wi a force and is mainly due to the hydrological forces and thus resulting in the flash or water at the surface in the form of a spring. Generally, these geysers are located near the volcanic areas and have a proximity to the magmas and the lavas flow. These impacts may be geologic and human-induced and they may also be created by the jet-like eruption of the gases inside the earth crust and thus comprise of the carbon dioxides and the sulfides. A basic eruption of the geothermal heat that is derived firm the hot interruptions of the crustal floors and the various moons in the solar system are also known to support this type of system also.Within the a group of climates, the two main types are wet tropical climates and tropical ________.
The two main types of climates within the group are wet tropical climates and tropical rainforest climates.
Explanation:Within the group of climates, the two main types are wet tropical climates and tropical rainforest climates. Wet tropical climates have warm temperatures year round with a high level of precipitation, typically in the form of rain. These climates have various subgroups that indicate how rainfall is distributed throughout the year, with some having a dry season and a wet season (monsoon). On the other hand, tropical rainforest climates, also known as tropical wet forests, are found in equatorial regions and are home to a great variety of plant and animal life.

How does a contracting protostar convert gravitational potential energy into thermal energy?
The answer of how it is convert is the sun generates energy by slowly contracting in size; converting gravitational potential energy into thermal energy and this is called gravitational contraction. Gravitational collapse is the narrowing of an astronomical object due to the effect of its own gravity, which tends to draw matter inward toward the center of gravity.
A contracting protostar converts gravitational potential energy into thermal energy through a series of processes involving gravitational collapse, kinetic energy transformation, and thermalization via particle collisions.
Protostars form from large clouds of gas and dust in space.Gravitational attraction causes these clouds to collapse inward.As the gas particles move toward the center, gravitational potential energy is converted into kinetic energy.The kinetic energy is further transformed into thermal energy through collisions among gas particles.This process heats up the gas, turning it into a hot, dense ball known as a protostar.As the protostar continues to contract, more gravitational potential energy is converted to thermal energy.The protostar's growing heat is radiated away, allowing the contraction to continue rapidly.The process slows down only when the protostar becomes dense and opaque enough to trap the heat generated.What sequence of events led to the origin of the Himalayas in Asia??

What would happen to the seasons if earth were tilted 35 degrees off its orbital plane instead of the usual 23.5 degrees?
Question Options:
A) The seasons would disappear.
B) Winters and summers would be more severe.
C) Winters and summers would be less severe.
D) The seasons would be shorter.
Answer: B) Winters and summers would be more severe.
Explanation: It is general knowledge that the current tilt of the earth is around 23.5 degrees. A tilt will significantly affect the current climate. The winters would be colder and summers would be hotter. This is because the temperature gradient between the equatorial centre and the pole would be more extreme this would increase wind speeds.
