What holds true for the angularity of sediment?
Which of the following statements holds true for the angularity of sediment? The farther sediment travels from its source, the smoother the grains become. According to Bowen’s reaction series, minerals can form in two ways.
What are four factors that determine whether rock melts?
igneous rock rock that forms when magma cools and solidifies.
What are three factors that affect whether rock will melt?
What Factors Affect the Melting Temperature of Rock?
- Heat. Heat is the most important factor affecting the melting point of rock.
- Pressure. A great deal of pressure is inside Earth, which causes heat.
- Water Content.
- Time.
Which of the following is an example of a Nonfoliated rock?
Examples of nonfoliated rocks include: hornfels, marble, novaculite, quartzite, and skarn.
What is made chiefly of rounded gravel?
A sedimentary rock composed of rounded gravel is called a. conglomerate. A sedimentary rock composed of angular gravel is called a. breccia.

Which of the following statements apply to Batholiths?
Terms in this set (74) Which of the following is NOT about Bowen’s reaction series?
What factors control the melting of rocks to generate magma?
Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways. Decompression melting involves the upward movement of Earth’s mostly-solid mantle. This hot material rises to an area of lower pressure through the process of convection.
What is the primary process that causes rocks to become sediment?
The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering—chemical weathering.
What are sediments in relation to weathering and erosion?
Weathering is the process that changes solid rock into sediments. Sediments were described in the Rocks chapter. With weathering, rock is disintegrated. It breaks into pieces. Once these sediments are separated from the rocks, erosion is the process that moves the sediments.
Which of the following rocks has a Nonfoliated or Nonbanded texture?
Texture
| Texture | Characteristics | Rock Name |
|---|---|---|
| foliated (banded) | thin layers of mica | Schist |
| foliated (banded) | thick layers of quartz, feldspar, and mica | Gneiss |
| non-foliated (massive) | welded quartz sandstone | Quartzite |
| non-foliated (massive) | sugary to course crystals, fizzes in HCl acid | Marble |
What are the characteristics of non-foliated rocks?
Overview. Nonfoliated metamorphic rocks lack foliated texture because they often lack platy minerals such as micas. They commonly result from contact or regional metamorphism. Examples include marble, quartzite, greenstone, hornfel, and anthracite.
