Atomic radius
Explanation:
A decrease in moving from the bottom of Group 3 to the top of the group shows an increase in trend from top to bottom.
The atomic radius of elements increases from top to bottom and decreases from the bottom to the top.
The elements in group 3 are B, Al , Ga, In and Tl
- Atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.
- Downs a group from top to bottom, atomic radii increases progressively due to successive shells being added.
- This compensates for the size reducing effect of the increased nuclear charge.

Earth's magnetic field doesn't have much to do with tectonic plates. But both are caused by movement of the magma. The magnetic field is caused by electrical currents flowing in the magma, roughly parallel with the Equator. Tectonic plates move around the surface of the Earth over the liquid magma.
So I'd go with B. mantle convection currents
Answer:
Option C
Explanation:
The heat released by the system is absorbed by the surroundings, then only the heat will be balanced.
The surrounding heat increases and so to balance that heat the system releases heat so that it can cool down because heat is neither created nor destroyed.
This is the first law of thermodynamics.

Answers:
1. A silver atom would have 47 protons and more neutrons than a cobalt atom and a cobalt atom would only have 27 protons and less neutrons than a silver atom.
2. D. Inert Inert means non-reactive.
3. Neon gas is a Nobel gas on the right side of the periodic table so it is an inert gas and does not react with iron.
4. Mass is neither created or destroyed so as Mr. Carney ran carbon in his body left as carbon dioxide. So the 10 lbs he lost left his body as CO2 through the lungs.
