Characteristics of sediments
https://australian.museum/learn/minerals/shaping-earth/characteristics-of-sediments/Sediments can be classified by their characteristics, which relate to how they have been transported and weathered and how far from their original source they have been deposited.

Classification of sedimentary rocks
https://australian.museum/learn/minerals/shaping-earth/classification-of-sedimentary-rocks/Sedimentary rocks are classified according to the predominant grain size present, as well as by their mineral content.

Concretions, Thunder Eggs and Geodes
https://australian.museum/learn/minerals/shaping-earth/concretions-thunder-eggs-and-geodes/Concretions are compact, often rounded, accumulations of mineral matter that form inside sedimentary rocks such as shale and sandstone or in soil.

Volcanic landforms
https://australian.museum/learn/minerals/shaping-earth/volcanic-landforms/Each type of volcanic massif (structure) contains lavas, pyroclastic rocks and intrusions, but these differ in proportions and compositions.
-
Magma
https://australian.museum/learn/minerals/shaping-earth/magma/Magma is hot molten mobile rock. Igneous rocks form when magma cools and solidifies. Magmas come out of active volcanoes as lavas.

Volcanic rocks
https://australian.museum/learn/minerals/shaping-earth/volcanic-rocks/Volcanic rocks are divided into three main types: basaltic, volcaniclastic and pyroclastic.
-
Tektites
https://australian.museum/learn/minerals/shaping-earth/tektites/Tektites are small, pebble-like glassy objects of Earth material that have been melted by meteorite impact, splashed up into our atmosphere, and fallen to Earth again under gravity.
-
Igneous intrusions
https://australian.museum/learn/minerals/shaping-earth/igneous-intrusions/Molten magma can invade the Earth's upper layers and then solidify as igneous intrusions.
-
Types of metamorphism
https://australian.museum/learn/minerals/shaping-earth/types-of-metamorphism/There are several different types of metamorphism, including dynamic, contact, regional, and retrogressive metamorphism, that form and shape rocks.

Water and sedimentary transport
https://australian.museum/learn/minerals/shaping-earth/water-and-sedimentary-processes/Water plays a vital role in most sedimentary processes. Pure water itself has little effect on rocks. It is the dissolved gases in water, particularly carbon dioxide, that cause the chemical decay of minerals and mineral dissolution.
