When burning, Yes.
A normal fire in a steel-frame building can soften the structure to the point of collapse.
Building laws / regulations require that all the structural steelwork is either covered in a protective coating (such as intumescent paint) or boxed in with fire-resistant plaster, so the fire can be extinguished before the building is weakened - or at least give people time to get out.
If that coating or plaster is damaged by impact or an explosion, the steel is exposed and the building can collapse relatively quickly.
(The common intumescent coatings just look like paint until exposed to fire, so the steelwork may appear to have no particular protection - but it always does).

See the images below - small buildings with steel-frame roofs after fires; you can see the amount of "sagging" and distortion on structures that have no particularly high loads.
These have burned long enough to destroy any protection, or they did not have any as the structure does not support occupied space.

Answer:
The material moved by erosion is sediment. Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. ... Water's movements (both on land and underground) cause weathering and erosion, which change the land's surface features and create underground formations.

I believe the answer is: <span>Ida, who is single and cares for her 85-year-old mother who is suffering from dementia and does not want any help
For most caregiver, the economic and physical burden that hey made for someone they care for would be diminished by emotional reward that they get from the caregiving.
When caring dementia patient, the caretakers often wouldn't receive any of this emotional reward.</span>
