Geologic Time - Quaternary Period

Summary

Quaternary period is the youngest period of the Earth. It is 1.8 million years ago to the present. Quaternary period has two epochs, the Pleistocene and the Holocene.

This is when the human race started.

Reflection

1.    What did you enjoy most about this project?

I enjoy finding pictures for this project.

2.    What was most challenging about this project? Why?

The most challenging part is to find the pictures of rocks. Because it took long time to find.

3.    What you change about this project and why?

I don’t want to change anything, because I think it’s perfect.

4.    What are 3 things that you learned from the project?

I learned when the human race started, when the ice age happened, and I learned how to make references.

THE STARS

Star is a giant ball of hot gases. It is made of gases.

Stars have different characteristics; they have different color, temperature, luminosity and size.

There are four types of stars, White Dwarfs, Main Sequence, Giants and Super Giants. 

H-R diagram is a chart that scientists use to classify stars by their types, sizes and temperatures.

Nuclear fusion is two hydrogen molecules become together to a helium molecule, this is how stars make energy. 

Stars are born in stellar nebula, and then become three types of star, sun-like stars, huge stars and giant stars. Sun-like stars go through red giants, planetary nebula, white dwarf, and finally become black dwarf. Huge stars go through red super giants, supernova and become neutron. Giant stars go through red super giant, supernova, and become black hole.

Mars

Mars is the 4th planet from the Sun.

Distance from the Sun is 228 million km.

Mass: 6.4185×1023 kg.

Diameter: 6794 km.

Rotation: 24hr 37min 23sec.

Mars has two moons.

Mars is terrestrial.

Mars is the 4th planet from the sun. Mars has two moons. It takes 24hr 37min 23sec to rotation, and takes 687days to revolution. Mars is made by rock.scientist think mars is the only planet similar with earth, they think human may move to mars.

Facts:
4th planet
time of rotation is smiler with earth

Hurricane Irene

Question

1.       What time of the year do hurricanes occur? Why do they only happen during that time?

Hurricane happens only in the summer, because the water is warm in the ocean in the summer.

2.       How can the timing of the tides (high or low) effect the devastation of a hurricane?

If hurricane happens the time during High tide, high water level would cause the hurricane more powerful. If it happens in the time of low tide, hurricane would be weaker.

3.       If an area is fully saturated, will a hurricane have more or less impact on an area?

A fully saturated area would have more impact from hurricane. Because the ground would be more soft which is can cause more damage.

4.       How does groundwater saturation affect rivers and streams?

Groundwater saturation would cause high water level of river and streams which is can cause flooding.

Reflection

1.       What is something that you liked about this Mini-project?

The most interesting thing for me is research.

2.       What was difficult for you on the project?

The most difficult thing for me is the five paragraphs.

3.       What would you change about your work on this project?

I will not to be absent next time.

4.       How did this project help you learn about Hurricane Irene?

I learned what cause hurricane.
