Answer: Crude Birth Rate and Crude Death Rate
Explanation: Both indicate the Natural Increase Rate of a country
Answer:
We would need the whole question or page even to solve this, my best shot would be 24 because 15+9= 24. If this is wrong please forgive me.
The lithosphere, which is the rigid outermost shell of a planet (the crust and upper mantle), is broken up into tectonic plates. The Earth's lithosphere is composed of seven or eight major plates (depending on how they are defined) and many minor plates. Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.[2]
Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Along convergent boundaries, subduction carries plates into the mantle; the material lost is roughly balanced by the formation of new (oceanic) crust along divergent margins by seafloor spreading. In this way, the total surface of the lithosphere remains the same. This prediction of plate tectonics is also referred to as the conveyor belt principle. Earlier theories, since disproven, proposed gradual shrinking (contraction) or gradual expansion of the globe.[3]
Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate movement is thought to be driven by a combination of the motion of the seafloor away from the spreading ridge (due to variations in topography and density of the crust, which result in differences in gravitational forces) and drag, with downward suction, at the subduction zones. Another explanation lies in the different forces generated by tidal forces of the Sun and Moon. The relative importance of each of these factors and their relationship to each other is unclear, and still the subject of much debate.
I’m confused, 3 observations on what?
Answer:
Cold Fronts
Explanation:
Fronts are geograpghical terms that describes various boundaries between air masses of different temperatures.
There are frour different type of fronts, they includes:
1. Cold fronts
2. Warm fronts
3. Stationary fronts
4. Occluded fronts
However, from the question, the answer is Cold Front due to the following characteristics associated with cold front.
Cold front is term that describes the movement of front in which cold air is replacing warm air at the surface.
Some of the characteristics of cold fronts include the following
i. Cold fronts always move faster than all other types of fronts.
ii. Cold fronts is characterized by most violent weather among all types of
fronts.
iii. Cold fronts normally move the farthest while maintaining their intensity, while also associating with thunderstorms.
iv. Cold fronts usually bring cooler weather, clearing skies, and a sharp change in wind direction.
All the above characteristics are presented in the question. Hence, the answer is COLD FRONT.
