4.a
What are the two main types of igneous rocks based on how they form?
The two main categories of igneous rocks are extrusive and intrusive.
What are the two main types of weathering?
chemical and physical
What are the three main types of rocks?
Igneous, Sedimentary, and Metamorphic.
What are the three main states of water?
ice, the solid form of water. liquid water, simply referred to as water. water vapor, the gaseous form of water.
Who's the best teacher?
Totally not Mr. Junior
Describe the texture of plutonic igneous rocks.
A texture of igneous rocks in which the crystals are too small for individual minerals to be distinguished without the aid of a microscope.
What is the difference between mechanical and chemical weathering?
the physical breakdown of rocks into smaller pieces without changing their chemical composition
What process forms sedimentary rocks?
sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.
What is the process called when water evaporates from the oceans, lakes, and land surfaces into the atmosphere?
Evaporation is the process that changes liquid water to gaseous water (water vapor).

Explain the key differences between the formation of plutonic and volcanic igneous rocks.
Volcanic rocks form when lava cools rapidly on Earth's surface, resulting in small crystals or glassy textures. Plutonic rocks form when magma cools slowly beneath Earth's surface, allowing large, coarse-grained crystals to develop.
Explain how plant root growth can contribute to mechanical weathering.
Roots can find their way into the tiniest cracks, often because water collects there, and force the crack to widen as the roots grow
Identify two ways that heat and pressure can be applied to existing rocks to create metamorphic rocks.
These huge forces of heat and pressure cause the rocks to be bent, folded, crushed, flattened, and sheared
Explain the role of water in the weathering and erosion of rocks and minerals.
Water plays a role in the formation of most sedimentary rocks.

Identify examples of intrusive igneous rock features and how they form.
There are many different types of intrusive igneous rocks. Some examples are: Diorite- black and white in color; used in building materials for roads; contains plagioclase, hornblende, and biotite.
Compare and contrast the effects of wind abrasion and water erosion on rock surfaces.
Wind erosion is determined mainly by wind direction, while water erosion is affected by overland flow and raindrop impact
Describe how sediments are transported and deposited to form sedimentary rocks.
If the sediment is buried deeply, it becomes compacted and cemented
Discuss how the distribution and availability of water shapes ecosystems and biodiversity.
Threats to the quantity and quality of water available for humans and ecosystems in North America include increases in drought, aridification

Analyze how the location of magma intrusion (surface vs. subsurface) would impact the type of igneous rock that forms.
Generation of magma takes place at the spreading ridges and at the trenches where plates are subducted, as well as at intraplate melting anomalies.
Analyze how changes in climate could impact the rate of weathering and erosion in a specific region.
High temperatures and greater rainfall increase the rate of chemical weathering
how human activities, such as mining or construction, can disrupt the natural rock cycle.
Human activities influence different factors that affect the rock cycle, for example, soil erosion and weathering.
Evaluate potential strategies for sustainable water resource management, considering the needs of human populations, agriculture, and the environment.
