When the settlers came to the United states, the native Americans helped them. When winter was over, they wanted to celebrate surviving through winter. The settlers invited the Native Americans and they had a big feast together.
Flattening a three-dimensional globe onto a flat surface isn't possible without some distortion. Mercator maps distort the shape and relative size of continents, particularly near the poles. Projections also distort distance, direction, scale and area.
The only disadvantage I could think of would be price of equipment needed to produce energy from the source (i.e. price of solar panels)
Based on the knowledge about radioactive elements, the decay of radioactive elements such as uranium creates heat especially in Earth's crust, where these elements are abundant.
<h3>What are radioactive elements?</h3>
Radioactive elements are elements which undergo spontaneous decay of their nucleus and in the process produce elements with smaller atomic masses with the release of radiation and heat.
Examples of radioactive elements include uranium and radium.
Therefore, the decay of radioactive elements such as uranium creates heat especially in Earth's crust, where these elements are abundant.
