That is because metamorphic rock is formed by parent rocks that are either sedimentary rock or igneous rocks and we can use the former rock type to distinguish the type of metamorphic rock, marble was igneous rock exposed to high pressure or temperature.
While the other two type of rocks are formed initially by sedimentation and volcanic movements and has no parent rocks.
Answer: During the day, especially in the afternoon, layers of air heat up, which is needed to create convective clouds
Explanation: Convective clouds, as the name implies, are created by convection. It is a process of raising warmer air of lower density than is the case with the surrounding atmosphere. Warm air contains more moisture, i.e. water vapor than cold, and when warm air rises during the day, it passes through layers of cooler air, causing water vapor to condense, creating droplets. During the morning, the air is generally cold, and during the day due to the rise in temperature, certain layers of air become warm, which then begin to rise and pass through the surrounding, cooler layers. Thus, the said condensation process takes place.
