Nastasia [14]3 years ago

When it's beneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks. With each eruption, rocks, lava and ash build up around the volcanic vent. The nature of the eruption depends on the viscosity of the magma.

C -- Explain the Big Bang Theory using astronomical evidence such as light spectra, motion
-Dominant- [34]

Answer:

Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.

"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."

A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.

Geneva says that the only thing that is needed for people to hear the sounds around us is a vibrating object. Do you agree with
elena-14-01-66 [18.8K]

Answer:

A vibrating object produces sound waves. Energy needs to be transferred from the vibrating object to the ear through a medium..

Explanation:

Sound is transmitted through sound waves and waves transfer energy from the source of the sound to it environment in a pattern of disturbance and travels through a media. Sound waves carry energy parallel to the motion of the wave .

Since sound involve sound wave and energy as seen in the above explanation. We can not agree with Geneva given that in order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium as a result of radio frequency signals that are leaking into our air causing them to bounce,reflect, enabling them to be heard in the human hearing range.

Distance east or west of the prime meridian is measured in degrees of?
My name is Ann [436]

Answer:

<u>Longitude </u>measure the distance east to west of the prime meridian that runs through greenwich england. Degrees are denoted by the greek word lamba.

Explanation:

  • Longitude gives us an angular measurement from 0 to 180 degrees. Subdivided into 60 minutes and 60 seconds. As longitude is singular at the poles.
  • Earth's tectonic plates move relative to one another in different directions at the speed of 50 to 100mm per year so the movement sin tectonic plates influence the latitudinal rotation which changes from year to year.  
  • These vertical lines define the places on the earth with their approximate sea level surfaces. The longitudinal belt is the equator at the zero degrees largest longitude on earth.
