<span>The correct answer should be snow. Snow falls when the temeprature is 32F or 0C. It doens't fall when temperatures are higher because the water vapor doens't crystalize, and it often doesn't fall when the temperature is much lower either. Sleet is that weird mixture between snow and rain that falls when temperature goes down but is not yet low enough for full snow to go down.</span>
Because of its Sharp tip the needle is able to put the force on a very small area of the cloth, producing a large pressure sufficient enough to pierce the cloth being stitched and allow to stitch the thread in and pull it out.
The correct answers are:
B. plant growth;
C. animal actions;
The mechanical weathering is a type of weathering where physical force is included into the breaking up of the rocks. The plants and the animals are both causing this type of weathering with their actions. The plants can cause mechanical weathering with their roots, as they grow and surround a rock, they are able to create such a pressure that they can break the rock apart. Also, as their trunks are getting bigger, if there's rocks right next to them, the pressure from the growing of the trunk will crack the rocks. The animals are able to move the rocks, as well as pushing them, or even deliberately throwing them, so they manage to break up parts of them and cause mechanical weathering.
