Iran and Saudi Arabia these are just the ones i know
Answer:
Top to bottom:
- Polar
- Continental
- Arid
- Tropical
- Temperate
Explanation:
The world is very diverse when it comes to climate. This comes from numerous different factors, with one of the most important ones being the angle at which the sunlight falls on the surface. Some parts of the world are hotter, some colder, some milder, and in some parts, there is a lot of precipitation while at some precipitation is something rarely experienced.
At and near the equator, the climate is tropical, having constantly high temperatures, high humidity, and a solid amount of precipitation. Just north and south of the tropical climate we have the arid climate, characterized by very high temperatures, low humidity, and very low precipitation. The temperate climate is found in the mid-latitudes, bordering the tropical and arid climates, having pleasant temperatures for most of the year, and a medium amount of precipitation. The continental climate is found in the mid-latitudes and deeper into the continents, having extremely low temperatures in winter and high in summer, with precipitation being manifested through both rainfall and snowfall. Polar climate is found around the poles, and this climate is the coldest on average, the precipitation is also very low and when there is some it is manifested through snowfall.
Answer:
D) the steady, clocklike decay of certain radioactive isotopes over time.
Explanation:
Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks.
For example, when rocks are formed, such as igneous rocks (formed when molten rocks cools), certain radioactive atoms are trapped inside the rocks during this formation process. Then these radioactive atoms decay over time.
The age of the rock can be estimated by comparing the occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay.
From the options;
A) this is about the formation of the radioactive molecules and not about radiometric dating
B) this is radiocarbon dating (cabon dating/carbon-14 dating)
C) the <em>assumption </em>is wrong since the radioactive isotopes decays not accumulate.
D) the corect option as I explained earlier.
