Compared to life on Earth's surface, space has a very different atmosphere. Because there is no gravity around you at all times when you are in space, your bones and muscles eventually weaken because they are not being utilized as often.
What is the atmosphere?The term atmosphere is the layers of gases environing a planet or other celestial body. Earth's atmosphere is constituted of about 78% nitrogen, 21% oxygen, and one percent other gases. The atmosphere is a layer of gases that borders Earth. It is held close to the surface of the planet by Earth's gravitational attraction.
For this reason, exercise is crucial for astronauts. However, doing a desk job all day is also not particularly healthy. You also don't perform many

3. Hydrosphere - snow, ice, vapor for example .
4. Biosphere - plants and animals.
Explanation:
The earth is divided into four major subsystems decided according to their 'constituents'. The four such subsystems are the lithosphere- land, hydrosphere-water, biosphere- living things, and the atmosphere- air.
These four subsystems are connected to one another, interacting with each other and maintaining life on earth.
The atmosphere consists of the air that surrounds the earth.
The lithosphere is the solid part of the earth like the mountains, valleys, and canyons, etc.
The hydrosphere is the water bodies such as snow, ice, vapor, etc.
The biosphere constitutes the living things on the earth like plants and animals.

As technology continues to improve and advance in the coming years, how do you anticipate this
will impact space travel and exploration? Consider things like robots, virtual reality, and any other
technological advances and explore how they may impact space travel
I personally dont think it'll impact a lot....I mean,sure, we have automatic cars,Tesla, but space travel...not really. It takes Millions of money just to get to Mars and it took us Decades to do it...it'll probably take 100 years or more to get further down in our solar system. For exploration, I also think it wont affect as much.
As technology improves and advances in the next years, it will have an impact on space travel and exploration, such as telescopes and satellites, which have provided information without the presence of humans in space.
What is space exploration?Space exploration is defined as the exploration of the universe using astronomy and space technologies.
While astronomers use telescopes to explore space, uncrewed robotic space missions and human spaceflight are both used to explore it physically.
Technology, such as telescopes and satellites, which have supplied information without the presence of humans in space, will have an impact on space travel and exploration in the next years as it develops and advances.
Therefore, the improvement in technology will impact the space exploration.

Distances for latitude are in _____ degrees or _____ of the equator.
Answer:
Distances for latitude are North degrees or South of the Equator.
Explanation:
Latitudinal lines are imaginary lines created by humans to serve their needs. These lines run from east to west as closed lines, or rather circles. Their starting point is the Equator which marks the middle part of Earth, and they spread from it in a northern and southern direction until the poles.
The Equator is at 0 degrees of latitude, and as mentioned it is the starting point for measuring all of the other latitudinal lines. There are latitudinal lines that stretch until 90 degrees North and 90 degrees South. The purpose of these lines is to help in orientation and to help with the absolute location of any place on Earth (in combination with the longitudianl lines). Also, they are very good in roughly representing the climate zones on Earth, the amount of sunlight a place gets, and dividing the globe into Northern and Southern Hemispheres.
