Fossils, or preserved parts of organisms from the distant past, have shown that species change over time. Radiometric dating can be used to determine the age of fossils by measuring the how much of the radioactive materials in each rock layer have broken down.
Granite is a type of intrusive igneous rock
Explanation:
An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.
Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.
A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.
This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.
Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.
Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.

carbon source Earth's crust
<u>Condensation</u> is the next step in the water cycle that is most likely to happen next as water molecules evaporate from a lake near the equator and rise into the atmosphere, as shown in the diagram below. and as the molecules travel away from the equator.
Explanation:
As the warmer air mass rises into the upper atmosphere, at the equator, it begins to cool because temperatures drop with altitude. The relative humidity of the air mass increases until it reachesdew point. The water vapor begins to condense into water droplets.
This air mass begins moving towards the poles (away from the equator) bringing with it clouds (condensed water vapor) that precipitate later on. This air mass begins to sinks because it has become denser with a decrease in temperature. As it sinks it replaces the air mass moving to the equator. The air rushing to the equator is replacing the rising warm air mass at the equator. This cycle continues.

As you can see in the table presented below, all of the gametophytes have seeds do not form in an enclosed structure and <span>undergo alternation of generations (marked in purple)
The gingkos were widespread in the distant past, but are now presented with only one species with fan-like leaves, the Gingko Biloba. (green)
The gnetophytes have three genera with very different looking species. One of the most iconic ones being the Welwitschia mirabilis often called the wise man's beard. (blue)
The conifers include redwoods, like sequoias and all, have pines as leaves and produce cones. (brown)</span>
