Answer:
The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer

A canyon is a type of landform formed over millions of years as flowing rivers wear away the land and carve out steep cliffs. A person standing at the bottom of a canyon would look up at the tall cliffs and think they were mountains because they are so high. Using this information, the landform at the bottom of a canyon is most like
Answer:
Has flat ground, and has a river flowing in the middle of it
Explanation:
The river in the middle created the canyon, and the flat land is the small/big space that wasn't used, and stayed flat

Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift?
A. The continents drifted apart due to repeated meteor impacts.
B. The continents were once connected as one landmass.
C. The continents have moved apart very quickly due to earthquakes.
D. The continents are magnetically pulled toward or pushed away from one another.
Answer:
Option B
The continents were once connected as one landmass.
Explanation:
The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.
The most appropriate option that shows this is option B: The continents were once connected as one landmass.
This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface
The statement that describes one of Wegener’s ideas that contributed to the theory of continental drift is the continents were once connected as one landmass. The correct option is B.
What is continental drift?Continental drift theory states that the motion of the earth results from the movement of tectonic plates. The theory tells that the different continents were fitting together.
According to the theory of continental drift, the world's continents were once joined together to form a supercontinent. However, because to some underlying earth factors, they gradually drifted apart over time.
According to one of Alfred Wegener's theories, the continents were previously linked together as a landlocked mass a very long time ago. The separation of the continents indicates that their positions on the surface of the globe are constantly altering.
Thus, the correct option is B. The continents were once connected as one landmass.
