Lava flows are the least hazardous of all processes in volcanic eruptions. How far a lava flow travels depends on the flows temperature, silica content, extrusion rate, and slope of the land. A cold lava flow will not travel far and neither will one that has a high silica content. Such a flow would have a high viscosity<span> (a high resistance to flow). A basalt flow like those in Hawai'i have low silica contents and low viscosities so they can flow long distances. Such a flow can move as far away as 4 km from its source and have a thickness of 10 m (Bryant, 1991). These flows can move at rates of several kilometers per hour (Scott, 1989). </span><span>More silica-rich flows can move as far away as 1.3 km from their sources and have thicknesses of 100 m (Bryant, 1991). These flows can move at rates of a few to hundreds of meters per hour (Scott, 1989). If a lava flow is channelized or travels underground in a lava tube then the distance it travels is greatly extended.</span>
Coastal plains and Interior plains is in elevation. Coastal plains have low elevation and low relief. Interior plains have varied elevation and low relief. Coastal plains also lie along the shore while Interior plains are surrounded by other hopefully this helps
A thematic map is designed to show distribution of human or natural features or data. Example:population
Answer:
Rivers of the Coastal Plain were a major means of commercial transportation during the 1700s and early 1800s. Cities founded along the fall line, called “fall line cities,” are located at the places where these rivers crossed the fall line, marking the upstream limit of travel. The city of Columbus, for example, was established where the Chattahoochee River crosses the fall line; Macon, Milledgeville, and Augusta are similarly located at the crossings of the Ocmulgee, Oconee, and Savannah rivers, respectively. These cities became important transportation hubs because traders could only travel upstream until they reached the waterfalls of the fall line. At that point they were forced to disembark and reload their cargo on the other side of the falls in order to continue their journeys. Columbus served as the upstream head of navigation for the Chattahoochee, as did Augusta for the Savannah River and Macon for the Ocmulgee River. After the first steamship arrived in 1828, Columbus became a gateway city for cotton. Above the fall line, flatboats and barges moved goods around the state. Below the fall line, steamships had unimpeded access to move goods, mostly cotton, into the Gulf of Mexico.
Answer:
The goal of sustainable development is to provide resources for the use of present populations without compromising the availability of those resources for future generations, and without causing environmental damage that challenges the survival of other species and natural ecosystems.
Explanation:
Why is sustainable use of natural resources important?
to ensure that natural resources are available for future generations
to help make daily life simpler by providing what every person needs
to encourage scientists to make new and elaborate discoveries
to prevent the exchange of resources from one region to another
The answer that you are looking for could be any of these actually The goal of sustainable development is to provide resources for the use of present populations without compromising the availability of those resources for future generations, and without causing environmental damage that challenges the survival of other species and natural ecosystems.
which is b. to help make daily life simpler by providing what evry person needs. i hope it is right
