What is the best description of the Earth’s rotation over its entire history quizlet?
What is the best description of the Earth’s rotation over its entire history? It has slowed down very gradually at about. 0015 seconds per century.
At what phase would you expect to find extremely high and low tides?
So spring tides bring the most extreme high and low tides every month, and they always happen – every month – around full and new moon. The 1st full moon of 2018 was also 2018’s closest supermoon.
What can we conclude about the structure of Earth’s interior knowing that the average density of Earth is higher than the average density of the rock on the continents and seafloor What can we conclude about the structure of Earth’s interior knowing that the average density of Earth is higher than the average density of the rock?
What can we conclude about the structure of Earth’s interior knowing that the average density of Earth is higher than the average density of the rock on the continents and seafloor? From the centre outwards, the correct order is: solid metallic inner core, molten metal outer core, silicate mantle and crust.
What is the hole in the ozone layer thought to be caused by quizlet?
When CFCs reach the stratosphere, the ultraviolet radiation from the sun causes them to break apart and release chlorine atoms which react with ozone, starting chemical cycles of ozone destruction that deplete the ozone layer.
What is the best description of Earth’s rotation over its entire history?
Test 2 (190-253)
|222. The crust of the Earth is covered by about ________ water in the hydrosphere.||70%|
|223. What is the best description of the Earth’s rotation over its entire history?||It has slowed down very gradually at about.0015 seconds per century.|
What two properties are responsible for the heating of Earth’s interior?
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.
What moon phase produces the highest tides?
The highest tides occur when the Moon is new or full. High tides sometimes occur either before or after the Moon is straight overhead. Sometimes there are really low tides called neap tides. Some places have only one high tide and one low tide in a cycle (24 hours and 50 minutes).
Which moon phases have the strongest and weakest tides?
At both full moon and new moon, tides are at their most drastic. High tides are very high, and low tides are very low. At full moon, the Moon and Sun are in a straight line on opposite sides of the Earth.
What do Moonquakes reveal about the moon?
Further analysis of lunar seismic data revealed that shallow moonquakes were the most high-energy seismic events on the moon. Shallow moonquakes lasted a long time, and compared to deep moonquakes or thermal quakes, they generated much more powerful vibrations.
Which body has the densest atmosphere?
Venus has the densest atmosphere of the terrestrial planets, consisting mostly of carbon dioxide, and the atmospheric pressure at the planet’s surface is 90 times that of the Earth.
What is the use of greenhouse effect?
The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Which earth material has the highest albedo?
The thicker the clouds, the greater their ability to reflect radiation back from Earth. Therefore, of thechoices available, thick clouds have the highest albedo.
What causes the ozone hole?
Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone’s ultraviolet radiation-absorbing capacity.
What are the dangers associated with the hole in the ozone layer?
Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
What is true of the ozone hole quizlet?
Terms in this set (36) What is true of the ozone hole? It is caused by the destructive reaction of chlorofluorocarbons with ozone in the atmosphere.
