What are two reasons Mercury lost most of its atmosphere? 

Mercury has almost no atmosphere. The planet's small size means that its gravity is too weak to hold down a normal atmosphere and There is a very thin atmosphere around the planet.

Compare how close Mercury & the Earth are to the Sun. 

At an average distance of only 57.9 million km, Mercury orbits closer to the Sun than any other planet. Earth orbits the Sun at an average distance of 149.6 million km. So you can see that Mercury is much closer, taking only 88 days to complete an orbit around the Sun. So, Mercury is the closest planet to the Sun.

Compare how much mass Mercury & the Earth have. 

Mercury and Earth are both inner planets. They both orbit around the sun, however they have different time periods. Mercury and Earth are rocky planets, and consist of land and rock. Earth's orbital period is 365 days, and takes twenty-four hours to turn a complete day and night.

How does not having an atmosphere affect the temperature on Mercury?

Instead of an atmosphere, Mercury possesses a thin exosphere made up of atoms blasted off the surface by the solar wind and striking meteoroids.

Can we afford a pet

Egg drop challenge

Today we have been doing the egg drop challenge, we had to make a safe way to not make the egg not brake, and we were lucky ..... to not brake our egg. The materials that we use, were old news paper, tap, fluff, string, bubble rap and carpet. We only had 30 minutes to make it, we had so much fun!   

I hope you liked it and have a amazing day! bye.

What Rocket did the Perseverance use to get into space?

          It is called Atlas V the V stands for the roman number 5 because it was there 5 attempt 

Describe the two vehicles that are being taken to Mars.

one of the vehicles are called Ingenuity Mars Helicopter it looks like a helicopter with 4 sharp blade to left it up into the air. and the rover looks like Wally-e off the movie Wally-e

Where does the mission plan to land on mars? What are they looking for?

Curiosity landed in Gale Crater, a dried-up ancient lake bed. Perseverance is going to a location called Jezero Crater, which is an ancient river delta. The terrain there is a little more treacherous than Gale, but the rewards may be richer.

How will the vehicle land without being damaged?

After its initial impact, the lander bounces along the martian surface until it rolls to a stop.

The airbags are then deflated and retracted, and the lander petals and rover egress aids are

deployed. Once the petals have opened, the rover deploys its solar arrays, and places the

system in a safe state.

Is gravity the same on all planets? 

Gravity is what holds our world together. However, gravity isn't the same everywhere on Earth. Gravity is slightly stronger over places with more mass underground than over places with less mass. NASA uses two spacecraft to measure these variations in Earth's gravity.

How is gravity related to mass? 

Gravity is the attractive pull between two objects that have mass. The strength of gravity is directly proportional to the amount of mass of each object.

Which planet would you weigh the most on? The least? 

Since Pluto was demoted to a dwarf planet, Mars became the planet where you would weigh the least. Jupiter is the largest planet in our Solar System with the most mass.

How would your life be different if you lived on a planet with higher gravity? With lower gravity?

These faraway planets might remind you of home they're rocky, smaller than gas It's possible that Earth and the other inner planets of our solar system It would take more energy to resist gravitational pull, so the structures we have.

Questions of Parihaka

Questions of Parihaka

What was the impact on Māori when of the New Zealand Company and other representatives of "The Crown" confiscated or purchased land very cheaply from Māori?

The New Zealand Wars were a series of armed conflicts that took place in New Zealand from 1845 to 1872 between the Colonial government and allied Māori on one side and Māori and Māori allied settlers on the other.

What happened to Māori who lost their land?

It has been estimated that by 1909 at least 18 million acres of it was in individual ownership, almost none of it had been settled by Māori. In the 20th Century there was further loss of Māori land to the Crown through private and Government purchases and under the Public Works Act, that sometimes breached the Treaty.

Where and how did they live?

They were taken to jail and they didn't eat, if they didn't eat they will die, so the Europeans had to let them free because if they die they would think they were the killers.

How do you think the New Zealand wars impacted on iwi and groups of people who were no longer able to live on their whenua?

The New Zealand war made everyone hart broken and they made everyone scared of the Europeans.  

What does the word PEACE mean to you?

world peace mean to me not war not fighting non violence

What is "passive resistance?

It is using non-violent opposition to authority, especially a refusal to cooperate with legal requirements.

What does the phrase mean?

phrase is a group of words that work together to make meaning.

What other ways are there to solve major issues between people / countries that do not use violence as a way of controlling others or solving problems?

Another way to become more passive is simply putting others in front of yourself more. That's not to say you should be a pushover and let people insult you, be afraid to speak up for yourself, or avoid conflicts like the plague, but sometimes help others achieve a positive outcome for them.

Who are some of the other world leaders who have used passive resistance? What was their cause and how is/was it peaceful?

The story of the peaceful resistance of the people of Parihaka is a treasure
