Cold air IS less dense, sinks, holds less vapor
Answer:
The real observations are:
Moon rises in east, sets in west each day.
stars circle daily around north or south celestial pole
Positions of nearby stars shift slightly back and forth each year.
A distance galaxy rises in east, sets in west each day.
We sometimes see a crescent Jupiter.
Explanation:
Mercury it can seen from the Earth but no it phases.
Moon is seen in all parts of the Earth, the only difference is that in north pole the stars moves parallel to the horizon.
By the rotation of Earth the relative position of stars changes a little bit.
In the north pole a galaxy can be observed and in the south pole 2 galaxies.
Jupiter is one of the planets that can be seen from Earth in some seasons and it changes the position due to the rotation of planets around the sun.
A planet beyond Saturn is not possible to be observed from Earth just with the naked eye.
The freshet is basically a flood that occurs because of heavy rainfall or because of the melting of a snow.
This type of flooding is most common in the valleys of the larger rivers, especially the ones that start their flow high in the mountains.
The large rivers have much more water, and they also have lot of tributaries, so when there's a heavy rainfall they receive enormous amounts of water, which easily causes a flood.
Also, when the snow melts, lot of water is released from it, and most of that water gets into the river, or first in its tributaries and that in it, so there's a high possibility of a big flood occurring suddenly.
The correct answer is - a. having differences.
The term heterogeneous is a term used to describe something that is different, that is not the same, or that there's multiple different things. This term can be used for various different things, including human societies, geography, biodiversity, etc.

Answer:
Paleozoic
Explanation:
The Paleozoic Era is a geologic era that lasted from 541 to 251.902 million years ago. This is divided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The swamps that were turned into coal over time grew during the Carboniferous period, which expands from 358.9 million years ago to 298.9 million years ago. The period is well-known because many coal beds were formed during that time period. During the Carboniferous, terrestrial animals were well-established. It ended with a minor extinction event known as the Carboniferous rainforest collapse.
