Answer:
This consists of pebbly beds associated with ancient blown sands, sometimes of considerable thickness. Above this series of deposits comes the Head or Rubble Drift, formed during a greater elevation of the land.
Answer:
Option D is correct.
Explanation:
Euphorbia esula is commonly known as leafy spurge, it's a creeping perennial native from central Europe, and most of north Asia.
The leafy spurge has deep roots, that store vital nutrients that allow the plant to recover from most control efforts.
Each plant can produce around 140 seeds per flowering shoot, these seeds are then expelled up to 15 ft. They can subsist up to 8 years in the soil.
This allows the plant to grow exponentially as it infests new regions.
Answer:
1.422
N/m²
Explanation:
pressure (P) = ρ g h
where ρ= density of continental crust
g= acceleration due to gravity
h is the depth given
density of continental crust is equal to 2.9 g/cm³
= 
g=9.81 m/s²
height = 50,000 m
now,
pressure (P) = ρ g h
pressure (P) =
=1.422 N/m²
It is the Line of longitude
