What kind of plate boundary is shown?

What are the four components of continental crust? (don't actually label)

What are the five major features of oceans?

What are the fundamental differences between oceanic & continental crust?

Label the interior structure of Earth.

The Hydrologic Cycle states that [blank_start]__________[blank_end]. It begins with [blank_start]________[blank_end] of water from [blank_start]________[blank_end]. As it is [blank_start]_________[blank_end] the water [blank_start]________[blank_end] and forms [blank_start]_______.[blank_end] It travels around the world until it returns as [blank_start]________[blank_end].

Minerals cannot be broken down into simpler forms by heat, cold, or reaction with other chemical elements.

What are two key factors that determine which atoms will unite with others to form compounds?

An atom that has lost or gained one or more electrons to become a charged particle is a(n) [blank_start]_____[blank_end]. Sharing electrons produces a(n) [blank_start]_______[blank_end] in which outer energy levels of the atoms overlap. The attraction of a negatively charged electron cloud to a positively charged nuclei is called a(n) [blank_start]_______[blank_end].

What are the six characteristics of minerals? It must be [blank_start]____[blank_end], and [blank_start]____[blank_end]. It must be a [blank_start]______[blank_end] and [blank_start]______[blank_end], with a [blank_start]_______[blank_end] structure, and have a [blank_start]_______[blank_end].

Polymorphism is __________.

The growth of minerals: 1. [blank_start]______[blank_end] from a [blank_start]_____[blank_end] 2. [blank_start]______[blank_end] from a [blank_start]_____[blank_end] 3. [blank_start]______[blank_end] state [blank_start]_______[blank_end]

What are the ways in which a mineral can be destroyed?

The six groups of predominate Rock-forming minerals are;

Define igneous rocks. Igneous rocks are rocks that formed from [blank_start]___________[blank_end].

Which is the correct statement about the four igneous rock compositions are basalt, gabbro, granite and rhyolite?

The viscosity of magma generally decreases with silica content.

The difference between basaltic and granitic magma is...

The temperature at which a mineral melts is roughly the same as the temperature at which it crystallizes.

Bowen's binary reaction series shows...

Label the intrusions.

Rocks with aphanitic textures are typically intrusive rocks.

Phaneritic textures are typically

The higher the silica content ...

The eruptive style of a shield volcano is ...

Stratovolcanoes have [blank_start]______[blank_end] eruptive styles, because of [blank_start]_____[blank_end] silica content.

What are three examples of chemical weathering?

Label different magma/volcanic rock types.

Label the Horizons of the soil
