The Sun is the largest object in the Solar System. The mass of the Sun is about 98% of the total mass of the Solar System. Structure of the Sun | Figure 9.1 Structure of the Sun showing some phenomena on its surface 1. The core is the innermost layer of the Sun. The temperature of this layer can rise to 15 000 000 ̊C.

Lightning bolts can travel 60 miles. 12. A lightning bolt travels at about 14,000mph and brings 300,000 volts of electricity to the ground. 13. The air located around a lightning bolt is heated to around 30,000 degrees Celsius.
He built his own telescopes and was the first to use to view the heavens in 1610. After doing so, he made many discoveries. He saw that Jupiter has moon orbiting around it, like the Earth. He made the discoveries of the four moons on January 7, 1610 and they are now called the Galilean moons. These are the largest of Jupiters moons.

We will be talking about parts per million (ppm). 1% = 1 x 10-2 = 10,000 ppm Pre-anthropogenic (1850 AD) concentration means CO2 levels in the atmosphere before humans started to burn coal, peat, oil, and gas in vast quantities. In 1850, the concentration of CO2 in the atmosphere was 280 ppm. CO2 is increasing in the atmosphere at the rate of approximately 2 ppm/yr due to human interaction. In 2013 AD, CO2 in the atmosphere is 396 ppm.
Magellan | Mission start: May 04, 1989Mission End: October 12,1994 | Venus | Made first global map of the surface of Venus. (1 point) | 6. You discover from your research that only one of the missions listed above returned samples to Earth. Which mission brought samples back to Earth? (2 points) Mars.
Which theory states that the universe began about 13.5 billion years ago? Big Bang. 5. Explain why the movement of galaxies supports both the steady state and the big bang theories- Both theories say that the universe is expanding. 6.
The craft landed later that same day only 15 minutes and 22 seconds later. Data During the flight, Mercury Redstone 3 Freedom 7 attained a maximum velocity of 8,200 km/hour and an altitude of 186.4 km. The capsule landed 483 km downrange from Cape Canaveral in the Atlantic Ocean. Shepard experienced a maximum g-force of 6 during the booster acceleration phase of the mission and slightly less than 12 on re-entry. The duration of the flight was 15 minutes and 22 seconds with weightlessness lasting about 5 minutes.
