What is heat transfer by convection possible only in liquids and gases?
Because convection occurs by convection currents. Convection currents occur as a result of the movement of a body. Since solids cant move, convection only occurs in fluid, i.e., liquids and gases
Why cant convection happen in solids?
Convection is the transfer of heat via the movement of warmer material nearest a source of heat toward colder regions, while colder material moves toward the heat source. Usually, the warmer material moves upward from the heat source (since "heat rises") and then is pushed outward toward colder regions, setting up a circulating current that pushes the colder material sinks downward and toward the heat source. Unlike conduction (where heat is transferred by direct contact with the heat source) or radiation (where the heat source sends out waves of heat), convection requires a circulating "current" -- where material moves or flows within a fluid, such as a liquid or gas. This flow is not possible within a solid -- where the material inside cannot move from place to place. Convection cannot occur in a vacuum, either, since there is no material to flow from one place to another.
How does energy travel to Earth?
There are three types of transferrable energy: conduction, convection, and radiation. Conduction- heat that moves from solid object to solid object by physical means. Convection- heat that moves about a gaseous object (think about boiling water) Radiation- light energy that can travel through space and needs no object to transfer through. The correct answer for this question would be radiation.
Convection cannot take place in a solid because the particles can only vibrate and not move from one place to another?
Sure there can be conduction, but quite often, most of the heat will be transposrted by convection, not conduction.
Why doesn't convection occur in a solid material?
Convection is fluid flow. It requires the movement of atoms and molecules within fluids (liquids or gases). In a solid, atoms and molecule are fixed in place and the material of a solid does not flow, so there can be no convection. Note 1. The answer above directly applies to 99.9% of the cases. There are peculiar amorphous materials, such as elastic materials, where one might consider them solid but they undergo some movement. There are also "visco-elastic" materials which exhibit both elasticity and flow. (For example below Earth's tectonic plates is the visco-elastic asthenosphere. Some artificial polymers and foams will behave partly as fluids and partly as elastic solids.) True solids do not flow. Note 2. There are links below related questions on why there is no heat transfer by convection in solids and why there is convection in fluids.
When convection occurs a solid moves from place to place?
false because it is a solid
What processes occur when a fluid or semi solid is heated?
convection
Why do convection currents not occur in some components of the structure of the earth?
Convection currents can occur in either a gas or liquid medium but not in a solid medium (so you can have them in air, and you can have them in magma, but you can't have them in solid rock) and they only occur when there is a temperature difference, so that hotter, less dense material will rise, and colder, denser material will sink.
Allows convection and can be a good conductor of heat?

How does convection take place in the mantle?
Convection in any fluid will occur when the lower portion is warmer than the upper portion. The less dense warm material will tend to rise while the denser cooler material will tend to sink. While the mantle is generally though of as solid, even solids can behave as viscous liquids over millions of years.
What must be true for metamorphism to occur?
the process must take place underground~ apex
What states of matter does convection occur in?
Under conditions of standard temperature and pressure convection is not possible in the solid state of matter.However under extreme conditions (e.g. the high temperature and pressure in the earth's mantle) convection is not only possible in the solid state of matter, but happens all the time just as in the liquid and gas states of matter but much slower.
