EXPLAIN why most earthquakes occur at the boundaries of different tectonic plates
olga nikolaevna [1]

Answer:

Explained as below

Explanation:

  • The three types of pf plate boundaries are spreading zones, transform faults and subduction zones. Most earthquakes occur along the boundaries of plate tectonics due to the effects of the earth's mantle layer that acts as a recycling agent and recycles 99% of the earth's surface layers from above.
  • Various tectonic forces and process act son these slabs and rocks from above and hence through the activities of erosion and denudation of the rocky masses these plates collide with each other as the earth is it's self not static its dynamic and moves continuously on a regular basis and hence changes take place on the surface of earth.
  • Thus it can be seen that the earthquakes and volcanic events occur at the plate boundaries and hence produce or are responsible for the various activities.

Geostrophic wind A) is slower than surface winds B) depends on friction C) flows from high pressure to low pressure D) flows par
Marina CMI [18]

Answer:

Geostrophic wind D) flows parallel to contour lines of upper-air pressure .

Explanation:

Geostrophic wind -

Air parcel generally moves from higher pressure to lower pressure due to pressure gradient force and left or right deflection due to coriolis force. When this deflection takes place a time comes when pressure gradient force and coriolis force becomes equal and the air parcel moves parallel to isobar then the winds are called geostrophic winds .

Earth’s climate is warming up because of factors like pollution. How much has the Earth’s climate warmed over the last 100 years
zysi [14]
The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.4Most of the warming occurred in the past 35 years, with the five warmest years on record taking place since 2010. Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months. https://climate.nasa.gov/evidence/
