- Thermosphere - Fourth layer of Earth's atmosphere.
- Aurora Borealis - Ionosphere layer of thermosphere.
- Large-scale air turbulence and mixing at this layer - Troposphere
- Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
- The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
- Maximum ozone - Ozone layer in Stratosphere
Explanation:
Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.
1. Troposphere -
- The first layer of the atmosphere.
- Weather occurs in this layer.
2.Stratosphere -
- The second layer of Earth's atmosphere.
- Contains Ozone layer.
3. Mesosphere -
- The third layer above the stratosphere.
- Coldest layer.
4. Thermosphere -
- The fourth layer of the atmosphere.
- Warmest layer.
- Ionosphere - lowest level of thermosphere above mesosphere.
- Aurora Borealis, Northern and Southern lights are seen in this layer.
- Exosphere - outermost layer of thermosphere.
- Satellites are in this layer.
- Outer space with no gravity.
Genetic drift is the dramatic almost sped up process of natural selection due to the untouched habitat the species I lives in. Genetic drift is characterized by the changing in alleles, whether more or less, natural selection could care less as long as they're creating diverse populations.
Answer:
A scientist who studies water and its properties is a hydrologist.
Explanation:
A hydrologist is a scientist linked to the study of water, both surface and underground, detecting cleanliness or contamination and proposing alternatives for its cleaning and conservation.
A hydrologist's research on the properties of water, its location, distribution and circulation contributes to the maintenance of the environment.
The other options are not correct because:
<em> A) </em><u><em>Entomologist
</em></u><em>: a scientist who studies insects.</em>
<em> B) </em><u><em>Chemist
</em></u><em>: a professional who studies the elements and chemical compounds and their properties.</em>
<em> D) </em><u><em>Oceanographer</em></u><em>
: study both oceans and seas, and their relationship with the environment, the atmosphere and the land.</em>
<em> E) </em><u><em>Toxicologist</em></u><em>: study the effects of toxic or harmful substances on living beings and the environment.</em>
A catalyst increase a chemical reaction, therefore making the answer B. Promotes a chemical reaction.
Hope I could help! :)
