C) convection cells (currents)
Explanation:
The movement of warmer cooler mantle rocks creating a circulation within the mantle is called a convection cell. These are the forces that drives the plate over asthenosphere.
- Convection is form of heat transfer predominant in liquids and gases.
- The mantle is molten and heated from heat within the core and the decay of radioactive bodies.
- Hot bodies are light and tend to be more buoyant. This causes warm mantle to rise to the surface.
- The cold part are denser and heavier, they sink in the mix.
- This creates pockets of circulation pattern within the mantle called convection cells.

Answer:
High explosives do not need to be contained to make their bang. Nitroglycerine, trinitrotoluene, and RDX are high explosives.
Explanation:
Number of moles of Cu in 63.546 g is 1 mole
1 / 63.546 = 0.0157366317
Number of moles in 1 g of Cu is 0.0157366317
0.0157366317 x 0.1431
0.002251912 moles will be the answer
kg and all the given units are units used to measure mass.
kg is the standard unit to measure mass
lets find the value of 0.00684 kg in all the given units
a. dkg
1 kg is equivalent to 100 decagram (dkg)
therefore 0.00684 kg is = 100 dkg/kg x 0.00684 kg = 0.684 dkg
this is not the given value therefore this choice is incorrect
b. 1 kg is equivalent to 1000 g
therefore 0.00684 kg = 1000 g/kg x 0.00684 kg = 6.84 g
this is the given value so this is correct
c. 1 kg is equivalent to 100 000 centigrams (cg)
therefore 0.00684 kg = 100 000 cg/kg x 0.00684 kg = 684 cg
this is the given value so this is also correct
d) 1 kg is equivalent to 1 000 000 mg
therefore 0.00684 kg = 1 000 000 mg/kg x 0.00684 kg = 6 840 mg
this too is correct
the incorrect answer is A. 0.0684 dkg
Answer:
True
Explanation:
The desert refers to a region of arid land which is characterized by extreme temperatures, extreme dryness, low amount of precipitation and generally harsh living conditions. Because of these harsh conditions, they have been tagged with various names ranging from 'Death Valley' to 'the place from where there is no return' etc.
Every desert is made up of 2 components: the <u>biotic (living) component</u> and the <u>abiotic (non-living) component</u>. The biotic (living) component consists of the plants and animals that have adapted to these harsh living conditions e.g. Cactus or Cacti, Holly plants, Camels, Lizards, Snakes etc. The abiotic (non-living) component consists of climate (subtropical deserts which are extremely cold or temperate deserts which are extremely hot), location, precipitation/rainfall
