This is known as the visible spectrum of electromagnetic radiation, or visible light. This is the frequency of light that we see, and which illuminates our world as it reflects off of objects. Compared to the full spectrum of electromagnetic radiation, the visible light portion is actually quite small.
Answer:
C .radioactive dating each year
Explanation:
In determining the absolute age of two rocks, the most important thing is the radioactive dating of the rocks to compare the radioactive isotopes within them.
Absolute dating involves ascribing numerical age to a rock body. It is usually done by the process of radioactive dating in which the number of daughter to parent isotopes are compared.
This helps to give a precise numerical age to a rock.
- The other choices are for relative dating.

There are more than one city on the High planes in Texas, and some of them are: Armadillo (190 000 people), Lubbock (270 000 or 315 000 with suburbs - it's also among the 100 most populous cities in the US!, but only 11th in Texas.), Pecos (10 000) , Odessa (110 000 )<span />
The correct answers are:
- It is a terrestrial planet;
The Earth is a terrestrial plant, and the main reason why it is classified as such is because it has a hard, rocky shell. The terrestrial planets seem to form closer to the Sun, or rather the star, while the gas planets further away from it.
- It has formed from gas and dust;
The most accepted theory about the formation of the Earth is that it formed from heated gas and dust, otherwise known as nebula. Under the gravity the material collapsed on itself, the particles started to merge with one another, and over time they became a large body, which under the influence of the spinning in a roughly circular manner, got the rounded shape.
