Answers

Answer 1

Answer and Explanation:

What stratigies can you use to reduce your electricity bill? How much money could you save?If possible, discuss your ideas with you classmates.

Answers

Answer:

A simple thing you can do is use less electricity. For example, people use electricity for light a lot and they can reduce that by just not using it in certain times like in the day time, they can open their windows for sun light and turn the lights on in night time. People also use too much electricity on gadgets and electronics and they can reduce that by just not charging them too often and using them a bit less. By doing these methods you can maybe save around 10$ to 100$ or even more.

Answer:

In geology, the term sial refers to the composition of the upper layer of Earth's crust, namely rocks rich in aluminium silicate minerals. It is sometimes equated with the continental crust because it is absent in the wide oceanic basins, but 'sial' is a geochemical term rather than a plate tectonic term.

What are some differences between Igneous and Metamorphic rocks?

Answers

Answer:

The main difference is that the Crystals in an igneous rock is shaped as it crystallized from a melt. The structure in a Metamorphic are earlier structures (Crystal, sedimentary fragments, etc ) that have been deformed or recrystallized due to heat or pressure or some chemical change.

Answer:

Igneous Rocks:-

1. Igneous rocks are formed when magma (or molten rocks) have cooled down and solidified.

2. Igneous rocks are commonly found inside the Earth’s crust or mantle.

3. The texture of igneous rocks depends on how fast it has cooled down. Textures range from coarse-grained to glassy.

4. They mainly have a crystal-like structure.

5. Igneous rocks are of two types – intrusive (solidified from magma below the earth’s surface) and extrusive (solidified from lava on the surface of the earth).

6. Examples:- Intrusive igneous rocks include – granite, diorite, pegmatite; Extrusive igneous rocks include – basalt, tuff, pumice, scoria, etc.

Metamorphic rocks:-

1. Metamorphic rocks are formed when other pre-existing rocks go through chemical and physical changes and form due to intense heat or pressure.

2. Metamorphic rocks are found on the Earth’s surface.

3. The texture of metamorphic rocks is foliated due to pressure. Some rocks may even appear to be non-foliated and banded.

4. They are very hard and may appear to be banded or layered.

5. Metamorphic rocks can be divided into two basic categories – foliated metamorphic rocks and non-foliated metamorphic rocks.

6. Examples:- Slate, marble, quartzite, phyllite, gneiss, hornfels, etc.

Which of the following volcanoes would you expect to erupt explosively : A volcano located near a subduction zone, or a volcano located on an island over a mantle hotspot? Explain your answer in terms of how the composition of the magma/lava impacts the physical properties (especially viscosity) of the magma, and how that would or would not lead to an explosive eruption. (7 points)

Answers

Answer:

The volcano over a mantle hotspot

Explanation:

I say this because lava comes from the grinding of those mantles, which melt rocks and make lava. If the mantles are super active, the lava will more than likely be explosive. Think of this (heat wise) as tea boiling in a kettle. The stove is the mantle, kettle as volcano and water as lava. When the mantles get hot enough they push that heat and pressure into the water, making it boil and when the steam starts to squeal out of the kettle, the volcano has erupted. Hope this helped!

14. Weathering and erosion occur when which two Earth
system spheres interact?
a. geosphere and biosphere
b. atmosphere and hydrosphere
c. biosphere and atmosphere
d. geosphere and atmosphere

Answers

Answer:

The atmosphere, hydrosphere, and biosphere interact with the geosphere through weathering and erosion. For example, rain and plants can weather rocks into sediments. Wind and flowing water can erode rocks and sediment and deposit them in new places.

Weathering and erosion occur when the geosphere and atmosphere two Earth system spheres interact. The correct option is D.

What happens when the atmosphere interacts with the lithosphere?

Wind erosion, where air currents wear away small pieces of rock over long periods of time, is one example of how the atmosphere affects the lithosphere. This can smooth out large areas of the lithosphere over very long periods of time, resulting in flat plains of soil or worn-down rock faces.

This precipitation connects the hydrosphere to the geosphere by promoting erosion and weathering, surface processes that break down large rocks into smaller ones over time. Erosion and weathering turn large chunks of rock—even mountains—into sediments like sand or mud over time.

When bodies of water or rain cause land formations to erode, the hydrosphere interacts with the geosphere. Rivers and rainstorms break down rocks into small particles while also forming new rock patterns. The hydrosphere generates snow and ice, which harden and cool the geosphere.

Thus, the ideal selection is option D.
