Ch 1  Section 2    A View Of The Earth - Quiz

This set of questions is taken from Chapter 1 Section 2.


Questions and Answers
  • 1. 

    What are the three main parts of the geosphere?

    • A.

      Atmosphere, crust, core

    • B.

      Crust, mantle, core

    • C.

      Lithosphere, mantle, core

    • D.

      Asthenosphere, lithosphere, atmosphere

    Correct Answer
    B. Crust, mantle, core
    Explanation
    The geosphere refers to the solid part of the Earth, and it is made up of three main parts: the crust, mantle, and core. The crust is the outermost layer and is divided into continental and oceanic crust. The mantle is the middle layer and is composed of hot, semi-solid rock. The core is the innermost layer and is made up of a solid inner core and a liquid outer core. These three parts work together to form the structure of the Earth.

    What is the driving force for the movement of the lithospheric plates?

    • A.

      Heat from the sun

    • B.

      Unequal distribution of heat within Earth

    • C.

      Heat in the atmosphere

    • D.

      Unequal distribution of heat in the ocean

    Correct Answer
    B. Unequal distribution of heat within Earth
    Explanation
    The driving force for the movement of the lithospheric plates is the unequal distribution of heat within Earth. This is because the heat generated from the Earth's core causes convection currents in the mantle, which in turn drives the movement of the lithospheric plates. The areas with higher heat levels rise, while the areas with lower heat levels sink, creating a continuous cycle of movement. This movement of the plates is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountains.

    The theory of plate tectonics helps scientists explain _________________ .

    • A.

      How ocean currents move over Earth's surface

    • B.

      Why hurricanes occur

    • C.

      How earthquakes and volcanic eruptions occur

    • D.

      Why Earth's core is less dense than the mantle

    Correct Answer
    C. How earthquakes and volcanic eruptions occur
    Explanation
    The theory of plate tectonics helps scientists explain how earthquakes and volcanic eruptions occur. Plate tectonics is the scientific theory that describes the movement and interaction of Earth's lithospheric plates. It explains that the Earth's lithosphere is divided into several large plates that float on the semi-fluid asthenosphere. These plates are constantly moving and interacting with each other at plate boundaries. When two plates collide, separate, or slide past each other, it can cause intense pressure and stress, leading to earthquakes and volcanic eruptions. Therefore, the theory of plate tectonics provides a framework for understanding the occurrence of these geological events.

    Which of Earth's spheres includes the oceans, groundwater, lakes and glaciers?

    • A.

      The atmosphere

    • B.

      The hydrosphere

    • C.

      The biosphere

    • D.

      The geosphere

    Correct Answer
    B. The hydrosphere
    Explanation
    The hydrosphere includes all of Earth's water, including the oceans, groundwater, lakes, and glaciers. It is one of the Earth's spheres that plays a crucial role in supporting life and regulating the planet's climate. The hydrosphere interacts with other spheres, such as the atmosphere and biosphere, through processes like evaporation, precipitation, and water cycle.

    Earth's four major spheres are the ______________________ .

    • A.

      Hydrosphere, atmosphere, geosphere, and biosphere

    • B.

      Hydrosphere, atmosphere, lithosphere, biosphere

    • C.

      Hydrosphere, geosphere, lithosphere, and asthenosphere

    Correct Answer
    A. Hydrosphere, atmosphere, geosphere, and biosphere
    Explanation
    The Earth's four major spheres are the hydrosphere, atmosphere, geosphere, and biosphere. The hydrosphere refers to all the water on Earth, including oceans, lakes, rivers, and groundwater. The atmosphere is the layer of gases surrounding the Earth, which includes oxygen, nitrogen, and other gases. The geosphere includes the solid Earth, such as the rocks, minerals, and landforms. The biosphere is the part of Earth where life exists, including all living organisms and their interactions with the other spheres.

    The theory of ________________ provides a model to explain how volcanoes and earthquakes occur and how continents move.

    Correct Answer
    plate tectonics
    plate-tectonics
    platetectonics
    Explanation
    Plate tectonics is the correct answer. Plate tectonics is a scientific theory that explains the movement of Earth's lithosphere, which is divided into several large and small plates that float on the semi-fluid asthenosphere beneath them. This theory provides a model to explain various geological phenomena, including volcanoes, earthquakes, and the movement of continents. It states that these events occur due to the interaction and movement of these tectonic plates.

    Take a look at the following diagram of the Earth's Crust.   Based upon what you see,  what are the two types of Crust in the geosphere?

    • A.

      Oceanic crust

    • B.

      Atmospheric crust

    • C.

      Continental crust

    • D.

      Seafloor spreading crust

    Correct Answer(s)
    A. Oceanic crust
    C. Continental crust
    Explanation
    The diagram of the Earth's Crust shows two distinct types of crust: oceanic crust and continental crust. Oceanic crust is found beneath the ocean basins and is generally thinner and denser than continental crust. Continental crust, on the other hand, forms the continents and is thicker and less dense than oceanic crust. These two types of crust have different compositions and characteristics, which contribute to the diversity of the Earth's geosphere.

    Based upon what you see in this diagram of the crusts of the geosphere.   Choose the BEST answer that is true.

    • A.

      Oceanic crust is thicker than continental crust

    • B.

      Continental crust is thicker than oceanic crust

    • C.

      Oceanics crust is much dryer that continental crust

    Correct Answer
    B. Continental crust is thicker than oceanic crust
    Explanation
    The correct answer is that continental crust is thicker than oceanic crust. This can be inferred from the diagram of the crusts of the geosphere, which likely shows that the continental crust is thicker compared to the oceanic crust.

    Glaciers would be a part of which of the following spheres?  

    • A.

      Atmosphere

    • B.

      Geosphere

    • C.

      Hydrosphere

    Correct Answer
    C. Hydrosphere
    Explanation
    Glaciers would be a part of the hydrosphere because they are large bodies of ice that form on land and are made up of frozen water. The hydrosphere refers to all the water on Earth, including oceans, lakes, rivers, and ice. Glaciers play a significant role in the water cycle as they store and release water over time, contributing to the overall water supply in the hydrosphere.

    The portion of Earth that supports the existence of living things is called the __________________.

    • A.

      Ecosystem

    • B.

      Habitat

    • C.

      Biosphere

    • D.

      Niche

    Correct Answer
    C. Biosphere
    Explanation
    The biosphere refers to the portion of Earth that supports the existence of living things. It includes all the ecosystems and habitats where organisms can live and thrive. This term encompasses the interactions between living organisms and their physical environment, such as the atmosphere, hydrosphere, and lithosphere. The biosphere is crucial for sustaining life on Earth as it provides the necessary conditions and resources for organisms to survive and reproduce.
