Since the invention of the telescope in the 1600s, astronomers have been fascinated by the surface of Mars and A______________. The first orbiter to visit Mars was NASA's Mariner 9, B______________. However, C______________, the planet was in a dust storm that completely obscured its view of the ground, so the orbiter had to wait for several months for the dust to settle. As the storm stopped, the highest points became visible and four huge volcanoes began to appear above the clouds. They were large and dome-shaped volcanoes, D______________. The lava in shield volcanoes has a lower silicon content than the lava in stratovolcanoes, E______________. Instead of spraying outwards, it moves in fluid paths, and the lava flows travel long distances across the ground. Over time, a gentle slope builds up as layer upon layer of lava are laid down, creating a wide, smooth volcano. The tallest of the Martian shield volcanoes is Olympus Mons, with a diameter of 624 kilometres and a height of nearly 26 kilometres above the ground. It is much taller F______________. By comparison, the tallest volcano on Earth, Mauna Kea in Hawaii, rises 10,000 metres above the floor of the Pacific Ocean. 1. when it arrived in 1971 2. whose mission was to map 70% of the planet's surface 3. than any other peak yet identified in the solar system 4. making it runnier and more liquid 5. have tried to take vivid pictures of it 6. when they reached the surface 7. which were similar to the shield volcanoes on Earth
