Suppose that you develop the following hypothesis: Some floods in rivers have enough energy to carry large clasts, i.e., particles of sediment about the size of your thumb or larger. If true, then sedimentary rocks from fluvial environments, i.e., rivers of the geologic past, should include such large clasts. If false, then any finding of such large clasts in a sedimentary rock cannot be associated with river water flows. What observations would support a true result

Answers

Answer 1

Answer:

b. stratigraphically alternating sequences of sandstones, conglomerates, and shales.

Explanation:

It is unlikely that one would find igneous rocks such as basalt and granite in fluvial environments. Coal is also not usually found in fluvial environments. Limestone prefers shallow and calm waters so would not be moved by water normally. This therefore invalidates options a, c, d, e and f.

For the hypothesis to be true, one would need to find conglomerates as these contain large clasts and are present in fluvial environments. Alternating sequences involving conglomerates and sandstones would indeed show that that some floods were able to carry large clasts.

what is cenozoic are​

Answers

Answer:

The Cenozoic Era meaning "new life" is the current and most recent of the three geological eras of the Phanerozoic Eon.

Definition: an era of geological history lasting from 70 million years ago to the present time in which there has been a rapid evolution of mammals and birds and of flowering plants.

The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammals – the Eutherians and the Metatherians. The extinction of many groups allowed mammals and birds to greatly diversify so that large mammals and birds dominated the Earth. The continents also moved into their current positions during this era.

Answers

Answer:

The Sahel is region A.

Explanation:

The Sahel is a region that stretched in a roughly east to west direction, located just below, or rather just south of the Sahara Desert. The Sahel is a semi-arid region, acting as a transitional zone between the desert and the savanna. This relatively narrow (for African standards) region stretches from the Atlantic coast to the Indian Ocean coast.

There are a total of ten countries where the Sahel occupies territory, with some countries having a larger share, while some very small ones. Even though the region is semi-arid, in the areas where there are rivers, it is actually offering very conditions for agriculture, and more and more people have been using this. Another important thing that needs to be mentioned about the Sahel is that it is the region in which the Great African Wall is being created, which is an attempt to make this region forested and prevent desertification, which also brings is economic benefits and a better life for the people in the region.

C: Canaries current
D: Alaska Current

Answers

California current.

I already knew this answer but a tip to help eliminate answers is that it said "western coastline". Florida is no where close to there. it's on the east side or north America and south. Then Alaska is on the west side but it's south-west, and i'm just gonna gO oUt oN a LiMb and say that the canaries current is is near canary because it is named after that and canary is in Spain so yeah
