    Well done to Gravedodger who answered 4 but I will claim virtual batch of hot cross buns thanks Ele.

    1. Where is the “Wallace Line” and what is it known for?
    It is a line that runs through the Staits of Molluca and to the west of Borneo which shows that to its east is the Australian fauna (cockatoos, kangaroos etc) and to the west Indo-European fauna (thrushes, monkeys, deer etc).

    2. What theory did Alfred Wegener come up with around 1883 and what area of science came from it?
    He showed that continental drift was true and from that has come the discovery of tectonic plates and their movements.

    3. On August 27 1883, a loud sound (possibly like distant gunfire” was heard on Rodriguez Island, near Mauritius in the Indian Ocean. What was the cause of the sound?
    The eruption of Krakatoa

    4. How far away from the origin of the sound was Rodriguez Island?
    2968 miles. There is an unsubstantiated report that the sound was also heard on a boat sailing just off the Cayman Islands in the Caribbean which is further away..

    5. As a result of the cause of this sound, what percentage of the earth’s surface is either believed to or was known to have audibly vibrated?
    The official record is 13% but that is based only on land movement but if the undersea movement was also taken into account the total would be much higher.
