An area has experienced weathering and erosion for many years. Over time, some rock formations have been left behind forming peaks and columns. What is a reasonable conclusion to draw? A. The rock that has been carried away over time is very hard and resistant to weathering and erosion.
B. The peaks and columns are made of rock that are very easily weathered and eroded.
C. Humans have protected the peaks and columns over time.
D. The peaks and columns are made of rock that are resistant to weathering and erosion.

D.

Explanation:

The rock that is left behind is there because it has resisted the forces of erosion.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
