i THINK it's false

online it explains "Because extrusive rocks make contact with the atmosphere they cool quickly, so the minerals do not have time to form large crystals. The individual crystals in an aphanitic igneous rock are not distinguishable to the naked eye"

Retrograde motion of a superior planet occurs when the Earth catches up to and passes the superior planet. Suppose a superior pl
joja [24]

Answer: 36 months

Explanation:

The earth complete its orbit in 12 months

While the superior planet complete its orbit in 18 months

Therefore since they are moving in the same direction, both planet will meet at the point where the superior planet and earth completes x and x+1 number of orbits.

Where x is a constant that represents number of orbits.

The period y when they both complete x and x+1 orbit respectively are;

y= 18x and y = 12(x+1)

Equating the two equations, we have,

18x=12(x+1) = 12x + 12

18x-12x= 12

x= 12/6= 2

Since x= 2

y= 18x=18×2= 36months

y= 36 months

Goodluck...

Earth science please help​
adoni [48]

Answer:

Geomorphological processes and resultant topography are related with  glacial, aeolian, fluvial and ground water movement.

  1. Outwash plain: <em>deposited mostly by water from melting glaciers.</em>
  2. Sand dunes: <em>not related to glaciation</em>
  3. Offshore bar: <em>not related to glaciation</em>
  4. Moraine: <em>deposited by glaciers</em>

Explanation:

Each and every geomorphological process has three types work. For e.g. erosional work, transportational work and depositional work.

  • Outwash plain produced by fluvio-glacial depositional work where firstly glaciers melt and then the water flows and deposits sediments in a flat area.
  • Moraine produced by glacial deposition. Glaciers carry sediments (pebbles, cobbles) and when it deposits in the valley floor it results a distinguished landform i.e. moraine.
  • Sand dunes produced by aeolian action (depositional work). When wind receives obstacle in the form of tree or stone in its way it deposits sand in desert area and produce sand dunes.
  • Offshore bar produced by marine processes. when sediments deposited in the coastal area in a huge quantity and friction take place between the wave and sea floor it creates offshore bar.
