This is primarily because the sun heats the earth's surface unevenly. As heat is trans- ferred to the air, we get regions of warm and cool air which can turn into regions of low and high pressure. This difference in pres- sure makes a force that causes the wind to blow.
So I would say the rising of warm air and the falling of cool air.
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.
settlement that has houses made of stone, adobe, and wood
Answer:
20% of number 1 to 70 has one or nine in it
Explanation:
20% numbers from 1 to 70 have 1 or 9 in the unit's digit. 1,9,11,19,21,29,31,39,41,49,51,59,61,69 this is that series of numbers .These are total 14 numbers out of 70 so 14/70×100 gives us 20 % occurrence of 1 or 9 at unit place.
