Answer:
it is when air is traped and builds up into high preshure.
Answer:
The Arctic fox (Vulpes lagopus) was thought to have evolved in Europe as the ice sheet expanded when a glacial period swept the Earth about 2.6 million years ago. so that means it evolved from Tibetan ice foxes
Explanation:
In the past century, the world has recorded a rapid increase and decrease in population in different geographical areas. This has been influenced by different factors such as urbanization and family planning.
Urbanization creates better employment opportunities and wages. It also provides better social amenities such as schools and hospitals. These encourage people to move from rural areas to urban areas in search of a better living. The migration results in a decrease of population is the rural areas and a rapid increase in population in the urban cities.
Increased access to contraceptives has enabled women to limit family sizes. Women are able to plan for the number of children they intend to have. This has generally decreased the population growth in developed regions.
The map and the globe both represent the same things, just that the maps come as flat surfaces, while the globes provide representations in spherical manner. They are actually much more similar than different, but there are still some basic differences that are worth mentioning.
The maps are simplified drawings, representations, on flat surface, coming in numerous different types of projections, some of which are more accurate, some less. The globes on the other hand are simplified representations in spherical manner, thus being able to capture the original shape of a space object better.
The maps come in numerous different projections. In general, the maps tend to have distortions, especially as the latitudes become higher, which is why they give us bad representation of the places that are further away from the Equator. The globes use mostly one projection. Because they have roughly the same shape as the object they represent, they do not have the distortions that the maps have, so they are more accurate.
The disc which contains spiral arms of the galaxy part would be used to study the birth starts in a spiral galaxy
Explanation:
- A galaxy has four parts and they are bulge, disc, spiral arms and halo
- Bulge primarily contains old stars, gas and dust.
- The disc contains the spiral arms also, it is the flattened portion of the spiral arms where we could find most of the young stars, gas and dust. Some old stars are also found in this region
- Spiral arms are only found in spiral galaxies. It is the curved extension begins from the bulge. Here, also you could find young stars, dust and gas.
- Halo is the part where we could find clusters or individual old starts and also the dark matter. The dark matter we can't see but can estimate the gravitational force.
