Answer:
Explanation:
In Winnipeg, summers are long and hot; winters are frigid, snowy and windy and it is partly cloudy throughout the year. During the course of the year, the temperature generally ranges from -19 ° C to 27 ° C and rarely drops below -30 ° C or rises above 31 ° C..
Answer:
windstorm, a wind that is strong enough to cause at least light damage to trees and buildings and may or may not be accompanied by precipitation. Wind speeds during a windstorm typically exceed 55 km (34 miles) per hour.

A,D,B,E,H,C,F, G is the right order
Answer:
Question 8 is true
.
Question 9, the correct answer is c, when basalt lava flows cover very large areas of continental crust.
QUESTION 10, the right option is d high viscosity, high gas content.
Explanation:
The viscosity of magma depends on its temperature, composition and gas content. Thus, magma with high levels of Sio2, silicon dioxide or silica increases the resistance flow as it increases lava viscosity, due to greater degrees of “internal friction”. Whereas basalt magma has a low-silica composition and flow fairly easily.
The Earth’s surface is transformed by high volume eruptions made of basaltic lava. Convection currents in the mantle find their way to the surface in randomly generated hot spots covering vast areas of lands. The geothermal conditions of these provinces affect their geography.
The volcanic explosiveness relies on the amount of gas and the degree of viscosity of magma. That is to say that high levels of gas mixed together with high viscosity rate result in highly explosive bursts. The eruptive force correlates to the internal pressure and the expansion of gas due to the friction caused by the resistance to flow.
