If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Answer: The fact that ashes and gases combined have the same mass as the wood you started with illustrates what law?

Rock layers extend laterally, or out to the sides. They may cover very large areas. This is especially true if they formed at the bottom of ancient seas. Seas are very large areas of water. Over time, sediment builds up on the seabed. They will be covered with the same types of material. As rocks form out of this sediment it will all be the same type. The rocks may be forced up above the water as Earths plates move. Rivers may eventually run across this area. The river will cut into the rock and erode it away. The layers of exposed rock on either side of the river will still match up. Look at the Grand Canyon in Figure 2.27. Its a good example of lateral continuity. You can clearly see the same rock layers on opposite sides of the canyon. The matching rock layers were deposited at the same time. They are the same age.

Answer: When rocks are forced up above the water as Earth plates move what may eventually happen?

My father was named James Page Jackson because he was born on the old Jackson plantation in Lancaster county, Virginia. He named one of his daughters Lancaster for a middle name in memory of his old home. Clarice Lancaster Jackson was her full name. A man named Galloway bought my father and brought him to Arkansas. Some called him by the name of Galloway, but my father always had all his children keep the name Jackson. There were fourteen of us, but only ten lived to grow up. He belonged to Mr. Galloway at the time of my birth, but even at that, I did not take the name Galloway as it would seem like I should. My father was a good carpenter; he was a fine cook, too; learned that back in Virginia. I'll tell you something interesting. The first cook stove ever brought to this town was one my father had his master to bring. He was cook at the Anthony House. You know about that, don't you? It was the first real fine hotel in Little Rock. When father went there to be head cook, all they had to cook on was big fireplaces and the big old Dutch ovens. Father just kept on telling about the stoves they had in Virginia, and at last they sent and got him one; it had to come by boat and took a long time. My father was proud that he was the one who set the first table ever spread in the Anthony House.

Sometimes traits can vary from parent to offspring. These changes are due to mutations. Mutations are a random change. Mutations are natural. Some mutations are harmful. In this case, the organism may not live to reproduce. The trait will not be passed onto offspring. Others variations in traits have no effect on survival. Can some mutations be good for a living thing? Other mutations can have great benefits. Imagine being the first moth that can blend into its background. It would have a better chance of survival. A living thing that survives is likely to have offspring. If it does, it may pass the new trait on to its offspring. Thats good news for the offspring. The offspring may be more likely to survive. Mutations are one way living things adapt to new conditions.

Answer:
Is it natural for some traits to vary from parent to offspring?
