The rock must be granite.
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.
I think they are just giving away free points
Answer:
Mesosphere lies in between 50 to 80 km above the earth surface and due to low density gases escape easily and hence it is colder.
Explanation:
Mesosphere has the capacity to not absorb the infrared radiation that's why the gases reflected from the earth surface escape the layer of mesopause and goes inside the thermosphere.
In the thermosphere, even the minute atoms of gases ca be absorbed by the layer which increases the air temperature and the air rises up hence making thermosphere as the hottest layer in the atmosphere.
