Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.

Question: "Pattern of Earth Process is?"

Answer: "Mountains grow and wither away"

Response: yes

The center of an atom is held together by powerful forces. This gives them a huge amount of stored energy. This type of energy is called nuclear energy. This energy can be released and used to do work. This happens in nuclear power plants where they split apart the nucleus of an atom. This splitting apart is called nuclear fission. Another type of nuclear energy happens in the Sun. Here the atoms nuclei are not split apart. Instead, the nuclei of the atoms are fused, or joined together. This process is called nuclear fusion. Some of the suns energy travels to Earth. This energy from nuclear fusion warms the planet and provides the energy for photosynthesis.

Question: "Do the atoms nuclei in the Sun split apart?"

Answer: "No, they fuse together"

Response: yes

I am very hungry. I look for my mother. When is dinner? I ask. Dinner is at six, my mother says. What can we eat? I ask. We can pick food from our garden, she says. I help her pick corn, beans, and peas. The corn is yellow and white. The beans are small and brown. The peas are green and round. I put the beans in a basket. I put the peas in a bowl. Mother brings the corn. We go inside. I have dirty hands. I wash my hands with soap and water. The water is warm. My hands are now clean. Mother lets me stir the beans. I fill a pot with water. Mother puts the corn into the pot. She puts the pot on the stove. The water boils. Mary is my sister. Mary puts four plates on the table. Each plate is blue. We each eat two pieces of meat. I eat more corn than Mary. Mary eats more beans than our mother. What did you learn today? Mary asks. I can spell ten new words, I say. Mary can only spell two words.

Question: "Why do I look for my mother?"

Answer: "To pick food from the garden"

Response:
no
