Answer:The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.
Explanation:
Law of Superposition
The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
Something that we hope you have learned from these lessons and from your own life experience is that the laws of nature never change. They are the same today as they were billions of years ago. Water freezes at 0° C at 1 atmosphere pressure; this is always true.
Knowing that natural laws never change helps scientists understand Earth’s past because it allows them to interpret clues about how things happened long ago. Geologists always use present-day processes to interpret the past. If you find a fossil of a fish in a dry terrestrial environment did the fish flop around on land? Did the rock form in water and then move? Since fish do not flop around on land today, the explanation that adheres to the philosophy that natural laws do not change is that the rock moved.
1What type of unconforruity is represented between layers E+I+F and E? Is intrusion C older or younger than
layers D, H, and A? Which principle do you apply to solve this? Is fault *5 older or younger than intrusion C? Which
principle do you apply to solve this? Rock sequence fi'om oldest to youngest:
Answer:
South America and Africa.
Explanation:
South America and Africa are the two continents which provides a strong evidence for the continental drift because their sides has a specific structure which can be fit with one another. The east coast of South America and the west coast of Africa fit together like pieces of a puzzle. The rock composition of east coast of South America and the west coast of Africa also similar which gives us a strongest evidence for the movement of big land masses away from each other that occurs with the passage of millions of years.
Studying geography helps us to have an awareness of a place. All places and spaces have a history behind them, shaped by humans, earth, and climate. Studying geography gives a meaning and awareness to places and spaces. It also helps students with spatial awareness on the globe. That’s why you should study geography.
