Lyle filled a glass bottle completely with water. He put the lid on tightly, then put the water in the freezer to cool it down quickly. Lyle forgot about his water until the next day. When Lyle took his bottle out of the freezer, all the water was frozen solid. The bottle had cracked in several places and was broken. If water in the ground acts like water in the bottle when it freezes, how does water in the ground affect layers of rock and soil

NEED HELP ASAP PLSSSPlease read the below paragraphs and then answer the 2 questions in complete sentences.Natural selection was proposed by Charles Darwin to explain how new species evolve. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like the successful individual. Over time, the species changes.In 1896, J. W. Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed. 1. What is natural selection? 2. How are peppered moths an example of natural selection?FOLLOW THE INSTRUCTIONS PLZZZ

- Rachel performed an investigation to study the thermal conductivity of four different materials. She started with four identically shaped rodseach made of a different material. Then, she placed one end of each rod into a pot of boiling water, which was at 100C.- After five minutes, Rachel measured the temperatures of the ends of the rods that were sticking up out of the pot to see whether they got hot. Her results are shown below.Thermal Conductivity InvestigationMaterial Temperature of End of Rod After 5 MinutesMaterial 1 41CMaterial 2 53CMaterial 3 98CMaterial 4 59C- Rachel knows that one of the materials is copper and that copper conducts thermal energy very well.
