stratovolcano is also known as a composite volcano. It is built up by many layers called strato‚ lava‚ tephra‚ pumice and volcanic ash that has become hardened. Stratovolcanoes have a steep profile and they have many explosive eruptions that cause craters that have collapsed called calderas. The lava flow from a stratovolcano normally cools before it has the chance to spread. This is due to the viscosity of the lava being extremely high. One of the most famous stratovolcanoes is Mount Vesuvius. This

The mass extinction of dinosaurs is still a mystery today but their are many theories supporting how and why approximately 70% of all living species on earth suddenly became extinct including dinosaurs‚ 66 million years ago. The most common and realistic theory is the astroid impact theory when a astroid 6-15 km in diameter hit earth with the force of five billion atomic bombs. Another possible theory is climate change‚ the dinosaurs didn’t adapt fast enough to the climate when it was changing and
