The mesosphere is the outermost layer of Earth.
4.Which of the following layers is defined by its physical properties?
mantle
crust
core
asthenosphere
you "teachers" never help
1. Hardness and carbonate content is a required tool Cleavageand luster is not a required tool
well what is it???
layer 1 crust
layer 2 mantle
layer 3 core
1. To determine whether a property must be observed using a tool or does not require a tool, let's examine each property:
- Cleavage: Cleavage refers to the tendency of a mineral to break along flat surfaces. To observe cleavage, you typically need a tool, such as a knife or a geologist's hammer, to see how the mineral is broken.
- Hardness: Hardness is a measure of a mineral's resistance to scratching. To determine hardness, you can use tools such as a mineral hardness scale (e.g., Mohs hardness scale) or a set of specific minerals of known hardness (e.g., fingernail, penny, glass plate).
- Luster: Luster describes how light is reflected from the surface of a mineral. It can be observed visually without the use of tools. You simply examine the mineral's surface and determine if it appears shiny (metallic luster) or non-shiny (non-metallic luster).
- Carbonate content: Carbonate content refers to the presence or absence of carbonate minerals in a sample. To observe carbonate content, you typically do not require a tool. You can perform a simple acid test by using dilute hydrochloric acid and observing if there is a reaction (bubbling) that indicates the presence of carbonate minerals.
2. The two correct techniques that scientists can use to determine the characteristics of Earth's layers are:
- Study how seismic waves travel through different layers: Seismic waves, such as earthquakes, travel at different speeds and change direction as they pass through different layers of the Earth. By studying the behavior of these waves, scientists can infer the characteristics of Earth's layers.
- Drill deep mines to obtain samples from Earth's mantle and core: The deepest mines on Earth provide access to samples from the Earth's interior layers. By analyzing these samples, scientists can gain insights into the composition and properties of the Earth's mantle and core.
3. The two correct statements describing Earth's interior layers are:
- The mantle is composed of silicate material: The mantle, which is located between the crust and the core, is mainly composed of silicate minerals.
- The asthenosphere is located below the lithosphere: The asthenosphere is a partially molten and plastic region below the rigid lithosphere. It is responsible for the movement of tectonic plates.
4. The layer defined by its physical properties is:
- Crust: The Earth's crust is the outermost layer and is defined by its physical and chemical properties. It is relatively thin compared to the other layers and consists of solid rocks.
