Important proprieties of Minerals



In the mineral properties I learn a lot information about minerals, mineral is a solid non-living thing form under the Earth. the minerals have properties and characteristics to describe them, these are used to help identify them. some minerals have differce between cleavage or fracture and metallic or non-metallic. at some minerals has softest or harder, Each mineral has specific properties of chemical composition. minerals has 2 types of minerals group is silicate minerals and non-silicates minerals, silicate from when molten rock cools, either at or the Earth's surface or deep underground.

Reflection
What did you enjoy most about this project and why?
I most enjoy about a lot minerals, know the minerals softest or harder, color and metallic or non-metallic.

What was most challenging for you during this project and why?
In this project I think some problem I don't understand how to do, I need to learn more about this minerals.

What new skills did you learn from doing this project?
I learn about minerals have properties and characteristics, each mineral has specific properties of chemical composition.

Is there anything that you could have done to improve any of your work?
I think I need to learn more, know more about this minerals topic.

Shaking Our World of Plate Tectonics

Summary of Earthquakes, Volcanoes, Faults, Earth's interior, plate tectonic and Plate Boundaries


Earthquakes is a sudden shaking of the earth's surface that often causes a lot of damage. When earthquakes happen will be caused by many people of the injury. Earthquakes are has fast and slow, has P- waves , S- waves and L- waves. but P- waves is move faster. S- waves is move slowly, also quakes are measured and recorded using a machine call a seismographvolcanoes an opening in the earth that islands erupts gases, ash and lava. it escapes from below the surface. A volcanic eruption occurs, magma that has erupted is called lava. The plates are all moving in different directing and at different speeds. The theory explains why earthquakes and volcanoes are likely to occur in particular locations and how new crust forms along the ocean floor. Faults are surfaces along which rocks have fractured and been displaced, there are there major tectonic plate movement caused by pressure over time, eventually leading to a break in the Earth's crust along the rocks.
The earth is divided into four main layers: the inner core, outer core, mantle, and crust. The core is composed mostly of iron and is so hot that the outer core is molten. Lithosphere is solid part of the earth.
There has different types of plate boundaries, between plates, volcanoes, earthquakes, mountains and trenches are all results of movement along plate boundaries. The Convergent Boundary is two plates that come together, to become oceanic and continental plate to create a mountain. Subduction Zone is when
1 plate goes under author plate, it is happening to volcanoes oceanic. The Divergent Boundary is mantle moves the plates is created by liquid rock pushing up from the mantle. Transform boundary are plates slide past each other and cause friction. Fault Zone is large fractures a break in the earth's crust to effect earthquakes. Earthquake effects damage to towns ad cities, Tsunami caused by an under water earthquake. Hot spot is unusually hot areas of the mantle core boundary effects volcanoes.

Do you agree with the theory of plate tectonics? Why or why not?
yes, I agree because the theory of plate tectonic say that earth's crust is broken up into pieces called plates, also is explain the continental drift theory and explain Earth's lithosphere is put together by the plate. The Earth;s internal structure of the outer most layer is divide into two parts, the outer layer of the lithosphere and the inner asthenoshpere. Therefore, Scientists have found seven major plates put in together.



Reflection
1. What did you enjoy most about this project and why?
I was enjoy about the video because I can put any song I like put in the I make the video.

2. What was most challenging for you during this project and why?
I most challenging about each topic should be take the test, because it is most difficult for me, I need learned more.

3. What new skills did you learn form doing this project?
I learn a lot information about plate this topic

4. Is there anything that you could have done to improve any of your work? Explain.
I think I need to improve the prediction map for the plate boundaries, because there was a lot information and evidence I don't understand need to learn more.

Phases of the moon

Waxing-{上弦月}getting bigger
Waning-{衰退}getting smaller
New Moon-{新月}no moon
Waxing Crescent- {新月形月亮}less than half
First Quarter-{第一季度}the half of the moon
Waxing Gibbous-{盈凸月}more than half
Full Moon-{满月}all light
Waning Gibbous-{亏凸月}more than half moon
Last Quarter-{下弦月}half of moon
Waning Crescent-{残月}less than half of moon

Summary
The phases of the moon are caused by the relative positions of the earth, sun, and moon. The moon goes around the earth in 27.3 days. As the moon makes its way around the Earth, we see the bright parts of the moon's surface at different angles. These are called phases of the moon. It takes one month (27 days) for the moon to go once around the Earth by revolution. The sun always lights up the half of the moon facing the sun. There are 8 moon fazes. When the moon is between the earth and the sun, it appears dark, a new moon. In between, the moon's lights up surface appears to grow waxing to full, then decreases waning to the next new moon.

How is earth affected by movement( revolution)?
The Earth affected by revolution, the Earth move around to the sun, and the seasons are explained by the tilt of the Earth's axis, when it is summer in the northern hemisphere, the north pole is pointed in the direction of the sun. season's are caused by earth's revolution around the sun and the tilt of it's axis (23.5 degrees).

Reflection
1.What did you enjoy most about this project and why?
I most enjoy about this project  of what is phases of the moon, how is moon product new moon,because in this project let me know answer moon process.

2.What was most challenging for you during this project and why?
I think I was most challenging this project about moon, how is moon change looks like.

3.What new skills did you learn from doing this project?
From this project I learn phases of the moon each moon vocabulary.

4. Is there anything that could have done to improve any of your work? Explain.
I think I need improve want to know more about phases of the moon, because some question I don't know.
