B. Cold, dense material moves horizontally, while hot, less dense material moves vertically.
C. Hot, less dense material moves horizontally, while cold, dense material moves vertically.
D. Hot, less dense material rises while cold, dense material sinks.
What happen in convection current can be described as
A: Cold, dense material sinks while hot, less dense material rises.
Some types of global convection cells that exists are:
Therefore, option A is correct.

A convection cell is a circular pattern of movement that occurs when there is a temperature difference within a fluid or gas. Hot, less dense material rises while cold, dense material sinks in a convection cell.
A convection cell is a circular pattern of movement that occurs when there is a temperature difference within a fluid or gas. In a convection cell, hot, less dense material rises while cold, dense material sinks. This creates a continuous flow of particles which transfers heat energy from one location to another.
This process can be observed in various natural phenomena such as a boiling pot of water, the movement of air masses in the atmosphere, or the circulation of magma within the Earth's mantle. It plays a crucial role in heat transfer, helping to distribute heat throughout a system or medium.

Which of these pairs of objects exerts the greatest gravitational force on each
other?
01) Object 1 and Object 3
02) Object 4 and Object 3
03) Object 1 and Object 4
04) Object 4 and Object 2
The diagram below shows four objects in the solar system which have equal masses. Object 4 and Object 2 these pairs of objects exerts the greatest gravitationalforce on each other. Thus, the option (d) is correct.
What is solar system?
The "family" of the Sun is referred to as the solar system. The solar system is the collective name for everything that rotates or travels around the Sun. At the head of this system is the Sun.
The Sun, a star, is surrounded by eight planets and other celestial bodies. Instead of having any intrinsic illumination, planets just reflect the light of the sun.
The force of gravity, often known as gravitation, affects every material thing in the universe. Any two mass-containing objects are attracted to one another by the gravitational pull. Gravity is stronger for objects with higher mass. Albert Einstein was the first to discover the Newton law of gravity.
Therefore, option (d) is correct.
