Chapter 5 Earth Science

Process whereby some minerals melt at a relatively low temp, while other minerals remain solid

Another factor that can affect the melting point of rock is pressure, it INCREASES with depth:

First minerals that crystallize from magma, are the last minerals melted during partial melting

One factor that can affect the melting point of a rock is temperature, it DECREASES with depth

Igneous rocks that cool slowly beneath earth's crust are:

Factors that affect a rock's melting point include:

Another term for crystal is:

A rock that has grains of 2 different sizes has what type of texture:

A rare, ultramafic rock that might contain diamonds is:

Extrusive rocks, which cool more rapidly than intrusive rocks, are generally more:

Rock formed from the crystallization of magma is called:

Rocks that have a spongy look due to the escape of gas bubbles are called:

Examples include granite, gabbro, diorite and dunite.

Examples include basalt, rhyolite, andesite, and obsidian.

Igneous rocks that cool quickly on Earth's surfaces are:

Obsidian cooled so quickly when it forms, has no/LARGE crystals:

Shows that as magma cools and crystallizes, minerals form in predictable patterns:

A vein of extremely large grained minerals

Igneous Rocks are formed when magma:

Most of the world's diamonds come from mines found in South Asia
