Answer: is expanding
Explanation:
A supernova is a stellar explosion that occurs as a result of the final stage of a star's life. This event can be very remarkable, even observable to the naked eye. This means that supernovae are characterized by very intense flashes of light that can last from several weeks to several months. In addition, its luminous intensity increases rapidly until it reaches an absolute magnitude greater than the rest of the galaxy, and then gradually loses its brightness until it disappears completely.
Then, a supernova is a very bright element, however, as its distance from the observer is greater, they will be less luminous (look fainter). This is presented as proof that we live in <u>a universe that is expanding</u> and is not flat.
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:
Abundant most likely means: more than sufficient without being excessive. plentiful implies a great or rich supply.
B a hurricane, because it’s a naturally occurring event
