[Answer] Lightning is how many times hotter than the surface of our Sun?

Step 1 : Introduction to the question "Lightning is how many times hotter than the surface of our Sun?"

...A bolt of lightning can reach temperatures as high as 30,000 kelvins, or 53,540 degrees Fahrenheit. That about five time hotter than the surface of the Sun. Of course, the surface of the Sun is actually its coolest layer. If you were to drill down to the Sun's core, you'd encounter plasma with temperatures as high as 15 million kelvins, or roughly 27 million degrees Fahrenheit. One main difference between the energy of lightning and the Sun's energy is the length of time it lasts. The Sun has been churning out heat and light for about 5 billion years. Lightning lasts for only microseconds. Source: Seeker.com

[Ans] In terms of surface area, what is the largest state in the United States?

Step 1 : Introduction to the question "In terms of surface area, what is the largest state in the United States?"

Alaska is the largest state in the United States by total area at 663,268 square miles, over twice the size of Texas, the next largest state. Alaska accounts for more than 17% of the land area in the United States. Counting territorial waters, Alaska is larger than the combined area of the next three largest states: Texas, California, and Montana. It is also larger than the combined area of the 22 smallest U.S. states. In a deal known as Seward's Folly, The United States purchased Alaska from the Russian Empire in 1867, for 7.2 million U.S. dollars at approximately two cents per acre.

[Answer] What percentage of Earth's surface is permanently covered with ice and snow?

Step 1 : Introduction to the question "What percentage of Earth's surface is permanently covered with ice and snow?"

...Snow cover can change dramatically with seasonal snow falls. During the cold of winter, up to 33 percent of the Earth's land mass may have snow cover. This is temporary, however. Permanent snow and ice cover is present on only 12 percent of the Earth's surface year round, with most of this found in the polar regions. The Earth's climate is a product of sunlight absorption by snow and ice, along with the land and sea. Snow and ice have a high ratio of reflected to transmitted sunlight (albedo.)

[Answer] What is the name of the "supercontinent" that once covered nearly one-third of the Earth's surface?

Step 1 : Introduction to the question "What is the name of the "supercontinent" that once covered nearly one-third of the Earth's surface?"

...About 300 million years ago, Earth didn't have seven continents, but instead one massive supercontinent called Pangaea, which was surrounded by a single ocean called Panthalassa. Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 300 million years ago, and it began to break apart about 175 million years ago. Pangaea was the most recent supercontinent to have existed and the first to be reconstructed by geologists.

[Answer] How many gallons of paint does it take to cover the outside surface of the White House?

Step 1 : Introduction to the question "How many gallons of paint does it take to cover the outside surface of the White House?"

...The White House is one of the most iconic buildings in the world. Every U.S. president since John Adams has called the White House home during his administration. Congress named the White House as an American national museum in the 1960s, preserving its antiquities for coming generations. To maintain the White House in good condition requires constant upkeep. To cover the president's home with a new coat of paint requires 570 gallons of paint. The White House interior includes 132 rooms, 35 bathrooms, 147 windows, 28 fireplaces, 412 doors, 8 staircases and 3 elevators. Source: WhiteHouse.gov

[Answer] What are oyster larvae called once they attach to a surface?

Step 1 : Introduction to the question "What are oyster larvae called once they attach to a surface?"

...Oysters reproduce by spawning tiny larvae. These navigate freely through the water until they come across a structure that will serve as a suitable habitat. They then settle on this structure, permanently attaching themselves to the surface. Once this occurs, they become known as spat. People cultivate oysters the world over for food and pearls. For successful oyster farming, the larvae much have suitable surfaces on which to settle within a hatchery or in a wild setting. This surface, or substrate, is usually the shells of other oysters or ceramic tiles. Once attached, oysters filter the nutrients they need directly from the water, making them self-sustaining.

[Ans] What naturally occurring phenomenon generates heat equal to five times the surface of the sun?

Step 1 : Introduction to the question "What naturally occurring phenomenon generates heat equal to five times the surface of the sun?"

At the core of the sun, gravitational attraction produces immense pressure and temperature, which can reach more than 27 million degrees Fahrenheit (15 million degrees Celsius). Hydrogen atoms get compressed and fuse together, creating helium. This process is called nuclear fusion.
