elephant
The largest land mammal extant today is the African bush elephant. The largest extinct land mammal known was long considered to be Paraceratherium orgosensis, a rhinoceros relative thought to have stood up to 4.8 m (15.7 ft) tall, measured over 7.4 m (24.3 ft) long and may have weighed about 17 tonnes.
Answer:
It is difficult to cross.
Explanation:
The Sahara desert is a vast region about the size of the continental United States that is extremely dry and barren. The lack of water resources in the desert make the land unsuitable for agriculture and human population.
As a result, the Sahara acts as a giant natural wall both economically, culturally, and socially since relations between states to the north and south of the desert are difficult.
Answer:
- Reduced snow accumulations
- Earlier snowmelt in the Spring
- Spring flooding
- Less water in streams
- Reduced water availability
Explanation:
Less snow will fall in Winter due to the higher temperatures and, thus, will not accumulate. When there is less accumulated snow on the ground and the snowpack is thinner, then the snowmelt will occur earlier and faster in the Spring.
Quicker snowmelt in the Spring will result in rivers overflowing their banks because they cannot hold such a rapid influx of water. Rapid water cycle runoff will cause Spring flooding.
The snowpack will, therefore, be depleted early in the Spring season, and due to the earlier and faster snowmelt, there will be less water in the streams during the Summer.
The consequential lack of slow mountain snowmelt during the summer season will result in rivers flowing much less vigorously and with less volume over water. This means that downriver communities will face summer water shortages.
Answer:
C. Trees with thin trunks
D. Fewer species of plants
Explanation:
If a forest has been logged once and regrew, that is a second-growth forest. Some characteristics:
- Thin tree trunks
- Fewer species of plants
- Little light reaching the forest floor
- Very high density of trees
Answer: The ice has been melting and declining
Explanation:
Due to an increase in industrialization, global warming is occurring. This has increased the average temperature around the globe considerably.
As you probably know, ice needs to be in a cold environment to stay frozen. <em>Arctic sea ice</em>, which is ice that floats in the sea near the Arctic, <em>has been </em><em>melting</em> due to global warming.
In addition, the land ice on Antarctica and Greenland has <em>also been </em><em>melting</em> due to global warming. The increase in average temperatures around the globe has created an environment that is <em>too warm</em> for ice.
In conclusion, <em>global warming</em> has caused Arctic sea ice, and land ice on Antarctica and Greenland, to <em>melt</em>. The globe <em>is warmer than it once was</em>. This means that the water that once was frozen is now melting. If we don't stop heating the planet, <em>sea levels will rise </em>due to the melting ice, and catastrophe will occur. Tens of thousands of animals will die, homes will be lost, and storms will increase in intensity and frequency if we don't reverse the effects of global warming <u><em>now.</em></u>
Save the Arctic, please.
