They are Cyanobacteria from Australia.
Answer:
Greenhouse effect
Explanation:
Greenhouse effect is the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Tropical climates are characterized by monthly average temperatures of 18 °C (64.4 °F) or higher year-round and feature hot temperatures. Annual precipitation is often abundant in tropical climates, and shows a seasonal rhythm to varying degrees.
Area. Around the equator, from 23.5° further north to 23.5° southern latitude.
Sun path. Sun at the zenith (90°) at least once per year, never lower than 43°
Average temperature. >20 to 30°C.
Minimal temperature. 0°C (no frost)
Maximal temperature. Up to 40°C (seldom more)
All tropical cyclones form over the ocean.
Answer: Option B
<u>Explanation:</u>
The tropical cyclones form above the ocean. To form a cyclone, warm, moist air rises above the ocean and as it rises, it creates an area of lower air pressure and air of high pressure area is also shifted to areas of low pressure area which when rises form clouds. This whole system of cloud and wind spins together fed by ocean's heat and as it spins faster and faster it results in a cyclone forming an eye in the center.
Answer:
Plate tectonics is the name for the process that forms Earth's features. Plates spread apart, bump together, slide under one another, or slide past each other. Forces on the surface also change the land. The movement of wind and water breaks rock down, and erosion wears Earth's surface away.
