6. What is a shock? *
O when gas and dust are swept up violently
O when gas and dust are swept up carefully
O when asteroids are swept up violently
O when gas and dust are loose in space
A shock refers to when gas and dust are swept up violently in space.
A shock is when gas and dust are swept up violently.
To determine the correct answer, we can examine the options provided and eliminate the ones that don't match the definition of a shock in the context of space.
Option 1 states that a shock occurs when gas and dust are swept up violently. In space, shocks are indeed produced when gas and dust particles are swept up violently as they collide with each other or with other objects, such as stars or planets. This option is plausible.
Option 2 suggests that a shock occurs when gas and dust are swept up carefully. However, shocks are typically the result of high-speed collisions or interactions, so the term "carefully" does not align with the concept of a shock. We can eliminate this option.
Option 3 claims that a shock is created when asteroids are swept up violently. While collisions involving asteroids can produce shocks, it is important to note that a shock is not exclusive to asteroid interactions. This option is partially correct, but it does not cover all scenarios where shocks can occur.
Option 4 proposes that a shock happens when gas and dust are loose in space. This statement is incorrect, as a shock is not defined by the presence of loose gas and dust particles. Eliminate this option.
Based on our analysis, the correct answer is option 1: "O when gas and dust are swept up violently."
