Yes, small amounts of water can lower the partial melting temperatures of silicate rocks by promoting the breakdown of mineral structures, reducing viscosity, and increasing mobility of magma. Water can act as a flux, helping to facilitate melting at lower temperatures.
The rate of weathering is influenced by factors such as climate, rock composition, and human activity. In general, weathering occurs faster in areas with high temperatures, heavy rainfall, and abundant vegetation. Rocks with high mineral content are more susceptible to weathering compared to rocks with lower mineral content.
High altitudes generally have lower temperatures compared to lower altitudes. This is because the air at higher altitudes is less dense and can hold less heat, leading to cooler temperatures.
Yes, small amounts of water can lower the partial melting temperatures of silicate rocks by promoting the breaking of chemical bonds and reducing the viscosity of the rock. This can lead to increased melting and magma formation at lower temperatures compared to dry conditions.

It is susceptible to heat -- it will melt.
Moonshine froze because its alcohol content is lower than that of other spirits, making it more susceptible to freezing at lower temperatures.
Rainforest trees often lack lower branches and feature straight trunks due to competition for sunlight. In dense canopies, trees grow upward rapidly to reach light, resulting in a tall, slender form with branches primarily concentrated at the top. This adaptation maximizes photosynthesis while minimizing energy expenditure on lower branches that receive little light. Additionally, the absence of lower branches reduces the risk of damage from falling debris and allows for easier growth in the crowded forest environment.
The best temperature range is 68 to 75 °F (20 to 23 °C). They can survive in much lower and higher temperatures but this makes them more susceptible to disease.
To crack cast iron, temperatures generally need to exceed 1,200°F (about 650°C). At this high temperature, the material becomes more brittle and susceptible to thermal stress. Rapid cooling or thermal shock can also induce cracking, even at lower temperatures, if the cast iron has been heated unevenly. It's essential to handle cast iron carefully during heating and cooling to prevent such damage.
Crape myrtle (Lagerstroemia) is generally hardy and can recover from freezing temperatures. If the branches and buds are damaged by frost, the plant may still produce new growth from the base or lower branches in the spring. However, severe freeze damage can hinder its overall health and flowering for the season. Regular pruning of any dead or damaged wood can help promote new growth.
The lower branches of your spruce tree may be dead due to lack of sunlight reaching them. As the tree grows taller, the upper branches block sunlight from reaching the lower branches, causing them to die off. This is a natural process known as self-pruning.
In general, most solids are more soluble at higher temperatures than at lower temperatures. However, there are exceptions such as cerium sulfate, which follows the opposite trend and is more soluble at lower temperatures than at higher temperatures.

Porcelain is generally more durable than terra cotta due to its higher density and lower porosity. Porcelain is fired at higher temperatures, which makes it denser and less susceptible to chipping and cracking. In contrast, terra cotta, being more porous, is more prone to damage from moisture and temperature changes. Thus, for durability, porcelain is the superior choice.
