Answer:
Climate change threatens coastal areas, which are already stressed by human activity, pollution, invasive species, and storms. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. Warmer and more acidic oceans are likely to disrupt coastal and marine ecosystems.
The correct answer is - 2. Earth's climates have changed and are likely to change in the future.
From what is known for the geologic past of the Earth, our planet's climate has been changing numerous times. The climate on the planet has varied from being predominantly wet tropical climate, to having ice ages, having multiple different climate types at the same time... The reasons for the changes in the Earth's climate are numerous, with the Sun's radiation, tectonic movements and activities, volcanic activity, outside influences like asteroid and meteorite collisions, the vegetation, and all of them have managed to create a very colorful climate history of the planet. This trend of climate change should continue in the future as well, as all of the aforementioned factors are still influencing the climate and on top of that the humans have become a factor in the climate change too.
Explanation:
step 1. let called the acute angles inside the triangle <1 and <2.
step 2. <2 +140 = 180 (supplementary angle)
step 3. <2 = 40°
step 4. <1 + <2 + 90 = 180. (interior angles of a triangle = 180°)
step 5. <1 + 40 = 90
step 6. <1 = 50°
Answer:
The Arctic and Antarctic have the same variations of day and night, but they are in opposite parts of the year.
Explanation:
The Arctic is the region at and around the Northern Pole, while the Antarctic is the continent at and around the Southern Pole. These are the two coldest areas on Earth, and even in what is considered summer the temperatures are very low. They have a lot of similarities but also some differences.
One feature that falls in both categories, similarity, and difference, are the variations of day and night. The similarity is in the fact that both regions experience sunlight constantly for half a year, and then experience night constantly for half a year. The difference though is in the fact that they occur in opposite parts of the year. When the Arctic has half a year of light, the Antarctic has half a year of night and vice versa, and this is due to the tilted axis of Earth.
Answer:
Human population changes due to population dynamics as birth, death and migration.
Explanation:
- The shift in the population of the US occurring during the year 2000 to 2004 as a result of the movement from the northeast, midwestern regions to the north and south west and to the southeast.
- Places like California and NY were losing population due to the high cost of living. States like Michigan had high unemployment rates. Other states gained population due to the lower living costs and availability of jobs.
