Answers
Answer:
1) A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The nearest star to Earth is the Sun.
2)satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth
3)rotation is a transformation that turns a figure about a fixed point called the center of rotation. • An object and its rotation are the same shape and size, but the figures may be turned in different directions. • Rotations may be clockwise or counterclockwise.
4)Earth's Equator, spelled with capital E, is a specific case of planetary equator. It is about 40,075 km long, of which 78.8% lies across water and 21.3% over land. In spatial geometry, as applied in astronomy, the equator of a rotating spheroid is the parallel at which latitude is defined to be 0°.
5)continent is one of several very large landmasses. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents.
6)iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water. Small bits of disintegrating icebergs are called "growlers" or "bergy bits".
7)Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
8)food chain is a linear network of links in a food web starting from producer organisms and ending at apex predator species, detritivores, or decomposer species. A food chain also shows how the organisms are related with each other by the food they eat. Each level of a food chain represents a different trophic level.
