World Geography Chapter 2 Quiz Review

What is the outermost layer of the Earth called?

• Mantle

• Crust

• Core

• Lithosphere

Answer explanation

The outermost layer of the Earth is called the crust. It is the solid surface layer where we live, while the mantle lies beneath it, and the core is at the center of the Earth.

Which type of plate boundary is characterized by plates moving away from each other?

• Convergent

• Divergent

• Transform

• Subduction

Answer explanation

Divergent boundaries occur where tectonic plates move away from each other, leading to the formation of new crust. This is in contrast to convergent boundaries, where plates collide, and transform boundaries, where plates slide past each other.

What is the primary cause of earthquakes?

• Volcanic eruptions

• Tectonic plate movements

• Weather changes

• Ocean currents

Answer explanation

The primary cause of earthquakes is tectonic plate movements. These plates shift and interact at their boundaries, leading to stress accumulation and eventual release, which we feel as earthquakes.

Which type of volcano is characterized by explosive eruptions and steep slopes?

• Shield volcano

• Cinder cone volcano

• Composite volcano

• Lava dome

Answer explanation

Composite volcanoes are known for their explosive eruptions and steep slopes, formed by alternating layers of lava and ash. This distinguishes them from shield and cinder cone volcanoes, which have different eruption styles and shapes.

What is the process called when rocks are broken down by natural forces such as wind or water?

• Erosion

• Weathering

• Deposition

• Sedimentation

Answer explanation

The process of breaking down rocks by natural forces like wind or water is called weathering. Erosion involves the movement of these particles, while deposition and sedimentation refer to the accumulation of materials.

Which of the following is a major factor in soil formation?

• Temperature

• Parent material

• Ocean currents

• Atmospheric pressure

Answer explanation

Parent material is a major factor in soil formation as it provides the mineral content and texture that influence soil characteristics. Other options like temperature and atmospheric pressure affect soil but are not primary factors.

What is the name of the fault line that runs through California and is known for its earthquake activity?

• San Andreas Fault

• New Madrid Fault

• Hayward Fault

• Cascadia Fault

Answer explanation

The San Andreas Fault is the most famous fault line in California, known for its significant earthquake activity. The other options, like the New Madrid and Cascadia faults, are located in different regions and are not primarily associated with California.

Which landform is created by the deposition of sediment at the mouth of a river?

• Delta

• Canyon

• Plateau

• Valley

Answer explanation

A delta is formed by the deposition of sediment at the mouth of a river, where the river meets a body of water. This process creates a landform characterized by a triangular shape, distinguishing it from canyons, plateaus, and valleys.

What is the term for the movement of sediment from one location to another?

• Erosion

• Weathering

• Deposition

• Transportation

Answer explanation

Erosion is the process that involves the movement of sediment from one location to another, often caused by wind, water, or ice. It differs from weathering, which is the breakdown of rocks, and deposition, which is the settling of sediment.

Which layer of the Earth is composed mostly of liquid iron and nickel?

• Inner core

• Outer core

• Mantle

• Crust

Answer explanation

The outer core is the layer of the Earth that is primarily composed of liquid iron and nickel, distinguishing it from the solid inner core, the mantle, and the crust.
