When comparing groups of stars, which group has relatively low
luminosities and temperatures?
Answer: Red dwarfs
Explanation:
Red dwarfs are thought to be the coolest star out of the rest. They are also the smallest. Because they are so cool, their luminosity is low as well on account of the fact that relatively speaking, the fusion taking place on their surface is little.
Red dwarfs are the most numerous star in the universe and the most numerous in the Milky Way galaxy as well. We just can't see them with out naked eyes because of their low luminosities.
Assume that the east coast of South America and the west coast of Africa are separated by an average distance of 4,500 km. Assume also that global positioning system (GPS) measurements indicate that these continents are now moving apart at a rate of 3.75 cm/year. If you could assume that this rate has been constant over geological time, how long ago were these two continents joined together as part of a supercontinent
Answer:
These continents joined together 120000000 years ago

Which three of the following statements are probably true? Use the information in the three maps below (the World Climate Region map, the World Bioregions map, and the World Population map) and their legends to guide you.
a. Evergreen forests are associated with a steppe-type climate.
b. The tundra bioregion is found only in the polar regions.
c. Continental climates are found in the Northern Hemisphere, but not the Southern Hemisphere.
d. Climate and bioregion play a significant role in human settlement patterns.
e. There is a strong correlation, and possibly even a causal relationship, between climate and bioregion.
Answer:c
Explanation:
Answer:
- Continental climates are found in the Northern Hemisphere, but not the Southern Hemisphere.
- Climate and bioregion play a significant role in human settlement patterns.
- There is a strong correlation, and possibly even a causal relationship, between climate and bioregion.
Explanation:
- Climate plays an important role in the location of plants and animals that in turn are crucial components of a bioregion.
- The Population Density map shows human settlement patterns. These patterns are consistent with the patterns on both the climate and bioregion maps.
- The color associated with the continental climate is blue. The color blue is found in the Northern Hemisphere but not the Southern Hemisphere.

The zone of convergence between sub-tropical and polar air masses, and where frequent traveling storms take place, is along the:
Answer:
The zone of convergence between sub-tropical and polar air masses, and where frequent traveling storms take place, is along the sub-polar latitudes.
Explanation:
Convergence zones are meteorological systems that have a strong impact on global climate quality. These systems are formed by the interaction of various meteorological events that occur between different latitudes.
The convergence zone, which encompasses the subtropical and polar air masses, has an influence on the amount of storms that occur frequently. This convergence zone is located along subpolar latitudes, being strongly influenced by the humidity found in this region.

Although freshwater biomes cover less than 1% of the Earth's surface, they are important because ________.
Explanation:
we depend on them for drinking water
they are home to lots of species
they are the source of our irrigation for agriculture
All of the above are reasons why freshwater biomes are important.
Although freshwater biomes cover less than 1% of the Earth's surface, they are important because fresh water is the lifeblood of our planet they are the source of our irrigation for agriculture , are home to lots of species, we humans depend on them for drinking.
What is need to conserve freshwater?Fresh water is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids.
Fresh water is vital to life and yet it is a finite resource. Although critical to natural and human communities, fresh water is threatened by a myriad of forces including overdevelopment, polluted runoff and global warming.
With this in mind, WWF partners with communities, businesses and others to decrease pollution, increase water efficiency and protect natural areas to ensure enough clean water exists to conserve wildlife and provide a healthy future for all.

Why is it unlikely for stable life to develop over the first few hundred million years of Earth's history
Answer:
In simple words, there existed no living on Earth for the first few million years since the environment was unsuitable for life. The original atmosphere of the Earth had a lot of water vapor but practically little oxygen. Volcanic activity blasted substances into the atmosphere such as nitrogen, carbon dioxide, hydrogen, and water vapor, but no pure oxygenation.
Explain the impact of human activities on soil and suggest measures to conserve it ??
Answer:
These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils. Soils are also subject to indirect impacts arising from human activity, such as acid deposition (for example, sulphur and nitrogen) and heavy metal pollution
List out three methods of soil conservation
Following methods are normally adopted for conserving soil:
Afforestation: One of the best ways to conserve soil is to increase the area under forests. ...
Checking Overgrazing: ...

The impact of human activities on soil are that some human activities have clear direct impacts.
These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils.
Measures to conserve it include crop rotation, cover crops, conservation tillage and planted windbreaks
What is land degradation?Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land.
It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.
Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.
It is estimated that up to 4% of the world's agricultural land is seriously degraded.
What is crop rotation?Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds.
A well-designed crop rotation can reduce the need for synthetic fertilizers and herbicides by better using ecosystem services from a diverse set of crops. Additionally, crop rotations can improve soil structure and organic matter, which reduces erosion and increases farm system resilience.
