Local winds are winds that do not blow for great distances. In this video, I cover two major types, sea and land and mountain and valley winds. These local winds occur because the land and sea heat up and cool at different temperatures and this produces wind due to low and high-pressure areas.

Difference between Organic and Inorganic Compounds
Organic compounds contain carbon. There are at least four important organic compounds, lipids, proteins, carbohydrates, and nucleic acids.
Inorganic compounds do not contain carbon and usually are more simple compounds.
There are some compounds that contain carbon and are inorganic like carbon dioxide.

In which John Green teaches you about the election of 1860. As you may remember from last week, things were not great at this time in US history. The tensions between the North and South were rising, ultimately due to the single issue of slavery. The North wanted to abolish slavery, and the South wanted to continue with it. It seemed like a war was inevitable, and it turns out that it was. But first, the nation had to get through this election. You'll learn how the bloodshed in Kansas and the truly awful Kansas-Nebraska Act led directly to the decrease in popularity of Stephen Douglas, the splitting of the Democratic party, and the unlikely victory of a relatively inexperienced politician from Illinois, Abraham Lincoln. Lincoln's election would lead directly to the secession of several southern states, and thus to the Civil War. John will teach you about all this, plus Dred Scott, Roger Taney, and John Brown.

Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. The Lincoln and Douglass debates of the 1850s fueled the argument over state's rights to decide on slavery and culminated when the two ran against one another in the Election of 1860: https://www.commonlit.org/text....s/the-election-of-18
In response to Lincoln's election, the South seceded from the Union and the Civil War began: https://www.commonlit.org/texts/the-south-secedes

#CrashCourse #Geography #Rocks

Today we're going to talk about SPAAAAAACE, but not like stars and satellites and stuff. Instead, we're going to talk about geographic space. In geography, we can look at the world and the places and spaces we inhabit with four distinct lenses: space as a container, topologically, socially, and how we perceive it. On this journey, we'll make stops in Antarctica, Haiti, and China as we introduce the tools you'll need from surveying and remote sensing to community-created maps to help us better understand and navigate our world.

Educational video for children to learn how to subtract fractions with the same denominator. To subtract fractions with the same denominator, we leave the common denominator and only subtract the numerators. Let's look at an example! To subtract five ninths minus two ninths, we leave the same denominator in the answer, in this case that would be number 9; and we subtract the numerators, that is, 5 - 2 which equals 3; this would be the numerator in the result which is three ninths (3/9). This educational video includes several exercises with fun examples for children to learn math while having fun. Excellent resource for elementary school.

Educational video for children in which children will learn the /m/ sound in English. Little ones will discover how to pronounce the sound of the letter M through a fun song and numerous examples alongside our favorite seal, Feli. Phonics is a very successful method used to teach reading through letter sounds. In this simple video for children who are beginning to read, we work on phonemic awareness and phonological awareness, two important skills for early readers and young children who are developing reading skills. It is an interactive video that asks viewers to participate by singing and repeating the sounds along with Feli.

This video is a very useful and interesting resource for children to learn the sounds of the English language. It is an excellent video for preschool, primary, and bilingual education.
