Answer:
Chemical weathering
Explanation:
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
Chemical weathering involves the decomposition of rocks due to chemical reactions between minerals such as calcite with water and gases in the atmosphere (e.g. carbon dioxide and sulphur dioxide). The solution of soluble minerals is particularly important in limestone landscapes.
Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum.
Essentially, water reacts with carbon-dioxide to form carbonic acid. It then seeps slowly through the roof of the cave, depositing calcium carbonate, which hardens and builds up over time to form a stalactite.
Heterozygous refers to a pair of alleles in which one is dominant and one is recessive. As you can see, all genotypes for possible offspring in the Punnett square are heterozygous. This means the probability of the parents having a child that is heterozygous is 100 percent likely.

Explanation:
Answer:
A student visits the beach during a very hot day. She steps on the sand and jumps because it is so hot as a result of "conduction."
Explanation:
The process of the conduction happens because of the flow of kinetic energy from one molecule to the other by direct contact. When she first steps the beach on the hot sand, after that the energy moves from the hot sand to the cooler body by conduction. While walking on the sand for few time, the feet will feel hot. The movement of the heat takes place from the hot sand to the bottom of the feet by conduction. When the objects come in contact with each other the heat transfers as a result of conduction.
