What Do Rockets Have On The End Of Them To Make Them Get Through The Atmosphere Without Burning Up?
Correct Answer
C. Blunt End
Explanation
Rockets have a blunt end to make them get through the atmosphere without burning up. The blunt end helps to disperse the heat generated during reentry, preventing it from concentrating in one area and causing the rocket to burn up. The blunt shape creates a shock wave in front of the rocket, which helps to slow it down and distribute the heat more evenly. This design is necessary because the intense heat and friction experienced during reentry can easily destroy a rocket if it does not have the proper shape to dissipate the heat.
3.
What Does The Launch Pad Do?
Correct Answer(s)
A. Move The Rockets From Place To Place
C. Use It To Build The Rocket On
Explanation
The launch pad is used to move the rockets from place to place and also to build the rocket on. It serves as a platform for assembling and preparing the rockets before they are launched into space.

What Is One Of The Things You Use To Make Rocket Fuel
Correct Answer(s)
A. Water
C. Nitro Dioxide
Explanation
Water and nitro dioxide are both used to make rocket fuel. Water is used as a propellant in some rocket engines, specifically in steam-powered rockets. Nitro dioxide, also known as dinitrogen tetroxide, is a highly reactive oxidizer commonly used in rocket propellants. When combined with a fuel, such as hydrazine, it forms a powerful and efficient rocket fuel. Therefore, both water and nitro dioxide are essential components in the production of rocket fuel.
5.
What colour does Earth look like from space?
Correct Answer
D. a giant blue ball
Explanation
From space, Earth appears as a giant blue ball. This is due to the fact that Earth's surface is mostly covered by water, which reflects the blue color of the sky. Additionally, the Earth's atmosphere scatters sunlight, making the planet appear blue when viewed from space. This phenomenon is often referred to as the "blue marble" effect.
6.
Which country made the soyuz spacecraft ?
Correct Answer
B. Russia
Explanation
Russia is the correct answer because it is the country that made the Soyuz spacecraft. Soyuz is a series of spacecraft designed for human spaceflight and is used by the Russian space agency, Roscosmos. The Soyuz spacecraft has been in operation since the 1960s and has been a crucial component of the Russian space program, including transporting astronauts to and from the International Space Station.
7.
What was mar's atmosphere made of?
Correct Answer
B. Carbon dioxide
Explanation
The correct answer is carbon dioxide. Mars' atmosphere is primarily composed of carbon dioxide, with traces of other gases such as nitrogen and argon. This composition makes the Martian atmosphere very different from Earth's, as Earth's atmosphere is mostly nitrogen and oxygen. The high levels of carbon dioxide on Mars contribute to its extremely cold temperatures and lack of breathable air.
8.
Why do you think you need a spacesuit in space ?
Correct Answer(s)
A. To breath
D. To survive
Explanation
The correct answer is to breathe and to survive. In space, there is no atmosphere and therefore no oxygen to breathe. A spacesuit provides a controlled environment with oxygen supply, allowing astronauts to breathe. Additionally, a spacesuit protects astronauts from the extreme temperatures, microgravity, and harmful radiation present in space, ensuring their survival.
9.
What is the main part of the space shuttle ?
Correct Answer(s)
A. The engine
C. The astronaut
D. The flames
Explanation
The main part of the space shuttle consists of three components: the engine, the astronaut, and the flames. The engine is essential for propelling the shuttle into space and providing the necessary thrust. The astronaut is crucial as they operate and control the shuttle during the mission. The flames refer to the combustion process that occurs within the engine, which generates the power needed for the shuttle to travel through space. Together, these three elements play a vital role in the functioning and success of a space shuttle mission.
