To write quantities in ordinary notation, you need to notice the power of the exponent.
If the power is positive, then you move the decimal point to the right by the number the power in exponent tells you.
If the power is negative, then you move the decimal point to the left by the number the power in exponent tells you.
We have:
3 x 10^-4 : the power of exponent is negative, therefore, we will move the decimal point 4 places to the left.
3 x 10^-4 = 0.0003 km
3 x 10^4 : he power of exponent is positive, therefore, we will move the decimal point 4 places to the right.
3 x 10^4 = 30000 km
The correct matches are:
1. Exosphere - Temperatures reach as high as 2000 C yet it feels very cold
This is the top layer of the atmosphere. The atoms are so dispersed that despite it having very high temperature it doesn't feel like it at all.
2. Thermosphere - Particles that have enough energy can escape into space
The thermosphere is the fourth highest layer of the atmosphere. The atoms in this layer are relatively distant from one another, so the particles that have enough energy manage to escape easily into the exosphere and then the space.
3. Mesosphere - It is the coldest region of the atmosphere
The mesosphere is the third highest layer. In this layer the temperatures constantly drop, and they go down to -85 degrees, making it the coldest layer by far.
4. Stratosphere - Ninety percent ozone is in this layer
The startosphere has a separte zone in it which is dominated by only one gas, the ozone. It is called the ozone layer, the one that protects the Earth from too intense UV radiation, and in fact over 90% of this gas is locate here.
5. Troposphere - It is warm due to the heat from Earth's surface
The troposphere is the densest and lowest of the layers. It is the one that also has Greenhouse gases which manage to trap the heat that is radiated from the surface of the Earth, thus keeping this layer relatively warm.
The question is incomplete, the complete question is;
Which of these best describes the relationship between the inner core, outer core, mantle, crust, asthenosphere, and lithosphere?
A: The coolest layers are farthest from the core.
B: The least dense layers are closest to the core.
C: The layers with the highest concentration of metals are closest to the crust.
D: The layers that remain in a molten state are closest to the crust.
Answer:
The coolest layers are farthest from the core.
Explanation:
When we talk about the internal structure of Earth, we mean the subdivisions of the solid Earth, that is, the concentric spherical layers that marks out the structure of the solid Earth.
The inner core is the innermost part of the earth's core and is known to have extremely high temperature. This high temperature steadily decreases as you approach the earth's surface.
Hence, the coolest layers are farthest from the core.
Answer:
The digestive role of the liver is to produce bile and export it to the duodenum. The gallbladder primarily stores, concentrates, and releases bile. The pancreas produces pancreatic juice, which contains digestive enzymes and bicarbonate ions, and delivers it to the duodenum.
Explanation:
The chemical process of digestion begins during chewing as food mixes with ... The esophagus is a tubular organ that connects the mouth to the stomach. ... Acid reflux or “heartburn” occurs when the acidic digestive juices escape into the esophagus. ... The secretions of the liver, pancreas, and gallbladder are regulated by ...
