select the correct answer.

the table presents the average day and night temperatures in five cities. it also reveals whether a city receives substantial rainfall (wet climate) or little rainfall (dry climate). which citys rocks are likeliest to experience frost wedging, and why?

\begin{tabular}{|c|c|c|c|}
\hline
city & climate & day temperature ($^{\circ}\text{c}$) & night temperature ($^{\circ}\text{c}$) \\
\hline
city a & dry & -11 & -30 \\
\hline
city b & wet & 5 & -4 \\
\hline
city c & wet & 14 & 6 \\
\hline
city d & dry & 26 & 17 \\
\hline
\end{tabular}

city a because the consistently subzero temperatures would prevent water from melting and escaping rocks.
city b because it is a wet region and the temperature fluctuates around the freezing point.
city c because it receives plenty of rainfall and the weather is moderately cool.
city d because the hot and dry weather would cause rocks to absorb water.

Sin agua líquida ni ciclos de deshielo. - **Ciudad B**: Clima húmedo ("wet"), la temperatura fluctúa cruzando el punto de congelación ($5^\circ\text{C}$ de día, $-4^\circ\text{C}$ de noche). - **Ciudad C**: Clima húmedo ("wet"), temperaturas siempre sobre cero ($14^\circ\text{C}$ y $6^\circ\text{C}$). Sin congelación. - **Ciudad D**: Clima seco ("dry"), temperaturas cálidas ($26^\circ\text{C}$ y $17^\circ\text{C}$). ## Selección de la opción correcta La Ciudad B cumple con ambas condiciones necesarias: disponibilidad de agua y temperaturas que oscilan por encima y por debajo de $0^\circ\text{C}$.

City A because the consistently subzero temperatures would prevent water from melting and escaping rocks.

City B because it is a wet region and the temperature fluctuates around the freezing point.

City C because it receives plenty of rainfall and the weather is moderately cool.

City D because the hot and dry weather would cause rocks to absorb water.
