What causes atmospheric convection? a. energy from deep in the earth heats the ground, heating air at the surface and causing the air to rise. b. energy from deep in the earth cools the ground, cooling air at the surface and causing the air to sink. c. the sun's energy heats the ground, heating air at the surface and causing the air to rise. d. the sun's energy cools the ground, cooling air at the surface and causing the air to sink.

answer:

the answer is d

explanation:

lighter (less dense), warm material rises while heavier (more dense) cool material sinks. it is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of earth. in the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.

a

explanation:

many plants naturally reproduce this way, but it can also be induced artificially. horticulturalists have developed asexual propagation techniques that use vegetative plant parts to replicate plants. success rates and difficulty of propagation vary greatly. monocotyledons typically lack a vascular cambium and therefore are harder to propagate.
