Yes, if you go and have a look at where the gutter pipe (drain pipe) comes down from the roof-tops and runs out onto the ground, you usually see wear patters near the outlet.
Another good place is, oddly enough, in old bathroom sinks., you can usualy see that the (usually shiny) porcelain is showing signs of wear i.e. not so shiny when a tap has been dripping. Careful though on this one! The matt coating could be lime which has gathered over time.
A really really good example is if you find a smooth round pebble. Much like the ones you see on the beach. usually pebbles get rounded by constant flowing water, banging into other stones on river beds etc...
Weathering might have the least effect in extremely cold and dry environments, such as polar regions like Antarctica. The lack of liquid water and the slow chemical reactions at very low temperatures limit the rate of weathering processes in these areas.
Both chemical and mechanical weathering breakdown a rock into particles, just in diffrent ways. Mechanical weathering is the physical weathering in which a rock is broken down into particles. Chemical weathering is the weathering in which rocks are disolved, decomposed , or loosend to change the minerals in the rock.
You might see a similar type of weathering in nature on coastal cliffs where the combination of wind, water, and salt spray gradually erodes the rock surface. Additionally, you could observe similar weathering processes in arid environments where extreme temperature fluctuations cause rocks to expand and contract, leading to cracking and breakdown.
Both are mechanical, physical changes, involving the removal of surface material by the action of wind or water. But both can also involve chemical changes which would tend to change the rate of erosion or weathering - for example, acidic rain might cause limestone to weather faster than neutral rain water would.
The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
give example of a real life situation where a substance's resisrance to weathering might make a difference
There are a few different weathering conditions that might affect copper. Rain and snow are some conditions that would affect copper.
Weathering might have the least effect in extremely cold and dry environments, such as polar regions like Antarctica. The lack of liquid water and the slow chemical reactions at very low temperatures limit the rate of weathering processes in these areas.
yes you can get a timetable. You can get timetables for work, school home etc. for school you might get a timetable for your lessons, for home it might be about your chores (house work) and work might be when your shifts are for example 9:00am till 4:00pm
It depends on the copyright status of the performance... for example a play may be restricted from copy and distribution. However, an original play might not be... I would contact the teacher, director, and/or school official for details. The school might also might have policies restricting it and if minors are involved, state and local laws might be in effect.
He was six. He might have started school around then.
It means there is an illness that is affecting a lot of people in one area. For example, if a lot of students at a school were becoming ill then someone might refer to this as "there's a bug going around".

Both chemical and mechanical weathering breakdown a rock into particles, just in diffrent ways. Mechanical weathering is the physical weathering in which a rock is broken down into particles. Chemical weathering is the weathering in which rocks are disolved, decomposed , or loosend to change the minerals in the rock.
The rates of mechanical weathering does not affect anything since the chemical properties remain unchanged. Only chemical weathering affects the chemical properties of an object.
The role of a committee is to accomplish a single task. For example, a committee might be formed through the PTA at a school to decorate for a school dance such as the Junior or Senior Prom..
