<u>From the given options which may suitably apply to the description of grid-lines of the map are
</u>
- They are measured in degrees
- They set up a reference system
- They divide Earth into four equal parts
Answers: Options A, B and E
<u>Explanation:
</u>
Option A describes that the grid-lines of the map are measure in degrees, which are very true as the grid are lined with angular measurement which thus be done in unit of angles and is in degrees only.
Option B says it develops the reference system which specifies about the area being plotted are grid depending upon the size which sets up the referential system of enumeration.
Option E is true as the world or the Earth has been divided into 4 equal parts through the Prime Meridian as the longitudinal line and Equator as the latitudinal line.
Answer:
Answer is option C (protoplanets).
Explanation:
During the formation of the solar system, a giant cloud of molecular dust collapsed to form stars, which were surrounded by a cloud of gas. The dust and other particles inside the cloud collide and merge together into larger mass through the gravitational and other forces. They continue to grow and become large enough to gravitationally attract other small celestial objects to form protoplanets. Some of the protoplanets continue their growth through the process called accretion and form planets.
Planetesimals - The small celestial objects formed during the early stages of the creation of the solar system.
Protoplanets - The objects formed when planetesimals became large enough to attract their neighboring celestial bodies through the force of gravity and grow by the process known as accretion, where they collide and merge together into larger bodies.
Extrasolar planets - The planets found outside our solar system (orbit another star, not the Sun).
Biochemical limestone is when the calcium carbonate is locked into the fossil shells and skeletons of marine organisms.
But chemical limestone is when the calcium carbonate is in the form of calcite mineral crystals.
Hope it helps!
It is a close race between A and D, i would thingk A because you can form a conclusion based on seeing all the observations on paper.
if you get it wrong...just tell your teacher and say that they are basically the same (that A and D are basically the same).
Hope that helped<span />
<em><u>C horizon formation :
</u>it is the unconsolidated material present beneath B horizon ..
when large soil particles and rocks break during the weathering of R horizon then it is formed but in dry regions gypsum and carbonates also get accumulated ..
<u>2)
</u>it is the B horizon present beneath A , O or E horizon ..it commonly accumulates clays .iron and different oxides .. also the other name of it is subsoil :)</em>
