Rock Types
We are going to have a look at rock types through using these 2 webquests below.
Discover How Rocks Are FormedStudents will work on these in pairs. Students will need to compile basic research notes as they go - you may choose which format is best for you for note taking.
Add 3 things to rock types vocab list as you go - remember once it's on the vocab list you can't add it again, so search for interesting information that others will enjoy reading!! :-)
Post your notes here
Hinuera ignimbrite
Hinuera ignimbrite (often marketed as Hinuera stone) is a yellow-cream to pale-brown ignimbrite containing angular fragments of pumice in a fine-grained matrix of volcanic ash. It is still quarried today, and widely used for cladding buildings in the North Island.
Andesite is a fine-grained, extrusive igneous rock composed mainly of plagioclase with other minerals such as hornblende, pyroxene and biotite. The specimen shown is about two inches (five centimeters) across.
The Moon
Moon Information page and a comparision between the Moon and the Earth.
Some Moon Facts from Kathrin via email - difference between Earth and Moon and how landforms were created Moon had very active volcanism in it's early history - there are still remnants of volcanoes, but most of all Moon was heavily bombarded by meteorites causing many of the craters we can see today. Earth also received meteorite hits but contrary to the moon today they are hard to make out - partially because of all the vegetation we have in contrast but also because of the lack of erosional forces that lack on the moon in contrast to Earth.
