Answer: Physical/Mechanical Weathering
Explanation:
Weathering is the process that breaks down rocks into smaller particles like sediment and soil. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. In this case, extreme heat during the day may have caused the rock to expand, only to shrink from the cold of the night. Over time, this weakened the structure of the rock, causing it to split and crumble, with outer layers flaking off in the process known as exfoliation.
Tides are caused by the specific alignment of the Moon, Earth, and Sun.
When aligned a certain way the the gravitational pulls basically share and add on to each other creating tidal waves.
An example of a certain alignment would be spring tides, which happen during a New or Full moon.
Examples: Boat sailors must watch out for tides and make sure to plan their sailing journeys according to the tide. They don't want to be caught against a tide, especially small board sailors.
Also fisherman keep note of tides since some sea life rely on tides for survival and feeding or some fish simply follow the movement of the tides. Fisherman use tides as an indication of when it'd be best to go fishing.
Answer: Yes, what you put is correct...
Explanation: Icelandic houses are built out of wood with grass growing over them, whereas Vietnamese homes are typically built minimally using reeds, etc. The main difference is that where the grass insulates from the cold (I’ve been in one and they really work!) the houses in Vietnam are built to keep all occupants as cool as possible.
