The stars that are visible in the local sky on any clear night of the year, at any time of the night, are called Circumpolar stars.
A circumpolar star is a star that is close to one of the celestial poles and never sets below the horizon hence they are visible from one location throughout the year and one can even see them in the daytime if the sun does not glare.
Answer:
C. its age
Explanation:
Rex is most likely trying to figure out the age of the rock formation. It is usually done by comparing the isotopic ratios of the daughter to the parent and their decay rates.
- This is known as radiometric dating.
- Here an exact numerical age of the rock is usually obtained by measuring these isotopic ratio.
- The rate of decay serves as a clock to measure how far the radioactive material has decayed in time
Answer:They would become igneous rocks
Explanation:
If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.
One will hardly spot any difference in their mineralogical composition as such.
The temperature of the sun does not any significant alteration on earth materials.
The heat from the interior has a very significant effect on rocks, especially sedimentary rocks.
Heat from the interior can reach a staggering 6000°C which is more than enough to cause a metamorphic change in a body rock.
In fact, at this temperature, igneous rock will be produced from the sedimentary rock.
2. A sand bar that completely crosses a bay, closing it off from the open ocean is none of these.
Answer:
D
Explanation:
They live in a territory and do not have a permanent area in where they have a state only a nation.
