Your answer is correct. A steamboat needed wood or coal to burn in order to create the steam that powered the vessel. The burning of wood or coal heated the water in the boiler, which then produced steam to turn the paddlewheels. The other options—rowers with oars, wind and sails, and a current in a river—are not necessary for the operation of a steamboat using steam power.
Steamboats
Before the 1800's, most boats were powered by oars, sails, or moving water. When those power sources were unavailable, boats could not travel. But beginning in 1807, Robert Fulton built the first successful business around the steamboat, which used a different kind of power
A diagram of a fire and boiler powering the paddlewheel of a steamboat is shown
most steamboats worked in this way:
1. a wood or coal fire was used to heat water in a tank called a boiler
2. the water expanded, boiled, and turned to steam, creating pressure inside the boiler
3. a hole in the boiler was opened, and steam rushed out, turning one or more paddlewheels
4. the paddlewheels propelled the boat through the water, even against currents and winds
based on this information, what did a steamboat need in order to sail using steam power?
rowers with oars
wind and sails
wood or coal to burn*
a current in a river

use the chart and map to answer the question
were there more enslaved people living in the united states in 1800 or in 1860
there were more enslaved people in the u.s in 1860*
there were more enslaved people in the u.s in 1800
there were an equal number of enslaved people in the u.s in both these years
based on the chart and map, how did westward expansion affect slavery in the united states between 1800 and 1860
the enslaved population decreased as the u.s economy became less dependent on agriculture
the enslaved population increased by more than 400% as several new slave states were admitted to the union
the enslaved population remained rougly the same but its percentage of the total population skyrocketed
the enslaved population decreased as the u.s economy became less dependent on agriculture.
Your answer to the first question is correct: there were more enslaved people in the U.S. in 1860. According to the provided data, the number of enslaved people increased significantly from 893,041 in 1800 to 3,953,760 in 1860.
For the second question, the correct answer would be: the enslaved population increased by more than 400% as several new slave states were admitted to the union. This reflects the history of westward expansion and how it contributed to the growth of the enslaved population, as new territories included new slave states and the agricultural economy remained dependent on slave labor during that time.

Select two main reasons that congress initially refused to annex texas, as supported by the information on this map.
If the united states annexed texas, it would almost certainly mean wear with mexico
if the united states annexed texas, it would enter as a free state and anger southerners
if the united states annexed texas, slave states would almost certainly outnumber free states
if the united states annexed texas, it would jeopardize the country's other claims in california
Based on the context provided regarding the map of the United States, the two main reasons that Congress initially refused to annex Texas are:
-
If the United States annexed Texas, it would almost certainly mean war with Mexico.
- Annexing Texas would have likely escalated tensions with Mexico, which still considered Texas part of its territory after it had declared independence.
-
If the United States annexed Texas, slave states would almost certainly outnumber free states.
- The potential annexation of Texas was related to the balance of power between slave and free states. Texas was expected to enter as a slave state, which could change the dynamics in Congress and give slave states more political power.
These options reflect the political and military concerns of the time regarding annexation.
