تتكون الأرض من أربعة أنظمة رئيسية متفاعلة: الغلاف الجوي (الهواء)، الغلاف المائي (الماء)، الغلاف الصخري (الأرض)، والغلاف الحيوي (الكائنات الحية). يفحص هذا الاختبار مدى فهم الطلاب لهذه الأنظمة، ومكونات كل منها، وكيفية عملها معًا كنظام واحد متكامل. كما يسلط الضوء على دور مهندسي النظم في تحليل هذه التفاعلات وتصميم حلول فعالة للمشكلات البيئية.

Question 1
Points: 1
Which of the following is NOT part of Earth's geosphere?
Rivers are part of the hydrosphere because they consist of liquid water, whereas the geosphere includes the solid rocks, soil, and landforms like mountains and volcanoes.
Question 2
Points: 1
What does the biosphere contain?
Explanation
The biosphere is the earth system that consists of all living organisms, including plants, animals, and microorganisms.
Question 3

The hydrosphere includes all of Earth's water, whether it is found in oceans, lakes, rivers, or as ice in glaciers and ice caps.
Question 4
Points: 1
What is the primary role of a systems engineer?
Explanation
Systems engineers focus on how different components of a system are designed and organized to work together effectively to achieve a specific goal or solve a problem.
Question 5
Points: 1
Which gases make up most of the Earth's atmosphere?
Nitrogen makes up about 78% of Earth's atmosphere, and oxygen makes up about 21%, together accounting for the vast majority of the air.
Question 6
Points: 1
Approximately how much of Earth's surface is covered by the hydrosphere?
Explanation
Scientific measurements show that approximately 71% of Earth's surface is covered by water, primarily by the oceans.
Question 7
Points: 1
If you were observing a mountain, a river, a cloud, and a tree, which one would be classified as part of the hydrosphere?
Explanation
A river is a body of liquid water, which directly classifies it as a component of the hydrosphere.
Question 8
Points: 1
Why do systems engineers work with other types of engineers?
Explanation
Systems engineers coordinate and integrate the work of various specialists to ensure that all parts of a complex system function together to achieve the intended result.
Question 9
Points: 1
Where in the Earth system can you find components of the biosphere?
The biosphere is the layer of Earth where life exists; it spans from the lower atmosphere where birds fly down to the deep ocean floor where marine organisms live.
Question 10
Points: 1
What is a key requirement for a system to be successful?
Explanation
For any system to function correctly and achieve its purpose, every part or component must interact and cooperate as intended.
