They found rocks from then and those rocks had the earliest fossils or life on earth.
Answer:
Answer:
Explanation:
Usually when the winds are from the south, and you have isotherms (temperature lines) perpendicular to the isobars (pressure lines) you have warm air advection (warm air moving up from the south).
Bolivia, the fourth-largest tin producer, has traditionally been a mining country-the answer is tin
Answer:
answer 15 correct option is b. 73.7°
answer 16 correct option is с. 47°
Explanation:
we know that on 4th july Northen hemisphere have summer and Washington, D.C also in Northen hemisphere
and sun present at 23.5° latitude
so latitude of sun is calculate as given figure below
= 90° - ( 39° - 23.5° )
= 74.5°
so correct option is b.73.7
this difference if because we take latitude 23.5° that is approx on 24 july
but july 4 latitude will be some low
and
we know during summer declination angle is + 23.5 in N.H.
and during winder declination angle is - 23.5 in N.H.
and at spring and autumn sun is at equator
the declination angle change is
declination angle change = 27.5 + 27.5 = 47°
A comet is a lump of rock and ice. Spacecraft have flown by comets. A comet only has a tail when it is near the sun. Most comets come from the Kuiper belt. A comet has actually been witnessed hitting a planet. Most comets have short orbital periods.
A comet is a tiny, frozen entity in the Solar System that heats up and starts to emit gases as it approaches the Sun. This process is known as outgassing. This results in an apparent atmosphere or coma, and occasionally a tail as well. These occurrences are caused by how the solar wind and solar radiation interact with the comet's nucleus.
The size of comet nuclei varies between a few hundred meters and tens of kilometers, and they are made up of loose clumps of ice, dust, and tiny rocky particles. A comet's orbit is typically very eccentric and elliptical, and its orbital period can range from a few years to possibly millions of years.
