Answer:
The best answer is A, "Mostly decayed matter with tiny rock particles.
Explanation:
Sand is one of the poorest soils, it has very, very low water holding capacity, as well as nutrients. I found the answer because we know it is not B, because sand does not have large rock particles, and we know that it is not c because sand has a very low water holding capacity. And we know that it is not D because it is kinda obvious that sand is not only found on the beach.
Really hope this helps! If I got it right can I have Brainliest?
I would say that in very fast moving water such as in a river, the cobble size could be transported because cobbles are 64-256mm so are quite big and in a quiescent stream won't move much but in a freshet say in a steep mountain stream they can be rolled along such as I observed in the local streams at a mining town during the Hurricane Fifi in Honduras in 1974.
Answer:
2 half lives
Explanation: 100% then 50% = 1 half life, 50% then 25%=2nd
Answer:
The answer is Option B: plate tectonics.
Explanation:
Plate tectonics is a theory about the structure of the earth's crust. In plate tectonics, the continents are viewed as a part of a system of rigid lithospheric plates which move slowly over the underlying mantle of the Earth. The model for plate tectonics builds on the concept of continental drift, which is an idea developed during the first decades of the 20th century. In continental drift theory, all the world's continents were once joined into a land mass that geologists have called Pangea during the late Paleozoic and early Mesozoic eras. It began to break up about 175 million years ago. In the beginning in the late Triassic, the continents began to break up with Laurasia comprising with what is North America and Eurasia and Gondwanaland which was South America and Africa, India, Arabia, Antarctica, and Australia. The shift in plates and their movement create mountain ranges and continents form and move to different latitudes that change the climate as these land masses moved.
