Answer:
some objects are too far or big to be fully observed from earth so the devices have to be launched, some devices are made to collect samples or bring astronauts into space.
Explanation:
Active sensors, provide their own source of energy to illuminate the objects they observe like ones on earth , An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or backscattered from the target.
Passive sensors, on the other hand, detect natural energy (radiation) that is emitted or reflected by the object or scene being observed. Reflected sunlight is the most common source of radiation measured by passive sensors. therefore some
A convection current is caused by differences in "temperature".
<u>Option: A</u>
<u>Explanation:</u>
The convection current is the outcome of variations in temperature. Like hot substance which is less denser, it rises while cool material which is more denser, it sinks. It is this motion that produces circulating processes in the environment, in water and in the Earth's mantle identified as convection currents. When air heats up it increases in the atmosphere, enabling colder air to circulate in below. This air flow generates waves, together with the Earth spinning. In effect, winds produce surface waves over the ocean.
Answer:
Agree
Explanation:
Because to have a good city you need water to drink and use in your everyday life. Without water, it is harder to live.
Answer:
Tsunami are waves caused by sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean.
